LiFePO4, Current Drain and the Icom 705/FT-817

Matt explains this very well

Hello

The LiFePO4 cells have a nominal voltage of 3.3V, fully charged at 3.6V and fully depleted at 2.5V. So, when fully charged a 4S (4 cells in series which is the standard “12V” configuration) LiFePO4 battery when it comes off the charger should read 14.4V, but this will slowly drop down to around 13.3V when taken off the charger.

The LiPo cells are a little higher with a nominal voltage of 3.7V, fully charged at 4.2V and generally accepted as fully depleted at 3.0V – so when fully charged a 4S LiPo will be 16.8V.

With both chemistry types, it is highly recommended not to use more than 80% battery capacity of the battery – with batteries like the bioenno they usually have a built in BMS (Battery Management System) that auto cuts off when the battery voltage gets to around that level. This BMS also allows the use of chargers without a balancing lead – but use the chargers that they recommend. I would suggest fully charged your bienno would be around 13.3V when fully charged (but off the charger).

I use a 3S LiPo for my FT-817 – it is only 2500mAh, but gives me multiple summit activations for SOTA and is incredibly light. I also have a number of 4S LeFePO4 batteries in 4200 and 8400 capacity that I use with 100W radios like the FT857/FT897 – a little heavier, but still gives me quite a bit of operating time although I do generally drop the power output down to 50-60W. These are all RC (Remote Control) aircraft style batteries and none have a BMS so need to be charged with a balanced charger – not overly expensive. When operating on a drive to summit or doing a WWFF activation (similar to your POTA), I also have a 4S 20Ah LiFePO4 that lasts for hours of use at 100W.

I anticipate that the 4S 4200mAh LiFePO4 batteries will be the primary battery used with my IC-705. Whilst convenient, the Icom 3Ah battery is expensive for what it offers and I doubt that I would go down that route – the BP307 is listed at AUD$180 each, whereas I can get 4S 4200mAh batteries at $80 each (usually under AUD$60 on special). So to get approx 12Ah of battery I would need 4 of the Icom packs (AUD$720) versus 3 of the 4S 4200mAh battery packs (at AUD$240 at normal price). To me it is a no brainer – yes the convenience of the Icom system is great, but bang for buck is way better with the RC style batteries.

RAC National HF Emergency Communications Frequencies

National HF Emergency Communications Frequencies

The following frequencies and modes have been pre-determined for suggested use of the Amateur Radio Emergency Service during a declared emergency, or a disaster declared or otherwise, occurring anywhere in Canada. These frequencies have been registered with the International Amateur Radio Union (IARU) for its listings of Canadian national emergency frequencies in IARU Region 2.

These are suggested frequencies and should not be construed as meaning that other HF frequencies may not be considered for Emcomm operations.

No Amateur Radio operator or group has exclusive ownership of any particular frequency on any band and, while common sense and courtesy logically would dictate that other Radio Amateurs should keep clear of frequencies being used for emergency or disaster operations, the affected ARES Net Control Station (NCS) must be prepared to move up or down from the pre-determined frequency, as required, in order to conduct operations. Entering into an on-air argument must be avoided.

SINGLE SIDEBAND CW DIGITAL
BAND FREQUENCY TACTICAL FREQUENCY TACTICAL FREQUENCY TACTICAL
80 M 3.675 MHz LSB Alfa 3.535 MHz Golf 3.596 MHz Mike
40 M 7.135 MHz LSB Bravo 7.035 MHz Hotel 7.096 MHz November
20 M 14.135 MHz USB Charlie 14.035 MHz India 14.096 MHz Oscar
17 M 18.135 MHz USB Delta 18.075 MHz Juliet 18.096 MHz Papa
15 M 21.235 MHz USB Echo 21.035 MHz Kilo 21.096 MHz Quebec
10 M 28.235 MHz USB Foxtrot 28.035 MHz Lima 28.096 MHz Romeo

 

The frequencies may also be used during a local ARES exercise or for RAC/ARRL Simulated Emergency Test (SET) operations held annually each Fall, provided such operations do not interfere with those of higher priority.

Each frequency has been given a tactical designation to facilitate quick change to another pre-determined frequency and/or mode by simply indicating the designation. Use of the tactical designations, while optional, is encouraged.

In all cases, these frequencies must be considered as being “plus or minus” to allow for QRM or other conditions impeding useful communications.

Should two or more ARES units wish to use a frequency at the same time for a simulated emergency exercise, consideration should be given to making the exercise “joint” and to work together.  Failing that, the frequency should go to the ARES group that first began operations there. Of course, if a real emergency should occur during the exercise and the frequency is required, the unit conducting the exercise is expected to cease transmissions immediately, relinquish the frequency and stand by in case assistance is requested.

Comments and suggestions concerning this list may be submitted, or for further information, please contact the Community Services Officer vo1dm@rac.ca .

VE3IPS COMMENT: IT IS STRONGLY RECOMMENDED THAT DIPOLE ANTENNAS BE USED FOR THE 80/40M BANDS. THE HIGHER BANDS CAN USE VERTICAL ANTENNAS. MOST TRAFFIC WILL BE REGIONAL IN NATURE. ARES NCS STATIONS SHOULD CONSIDER SOME FORM OF DIRECTIONAL ANTENNAS TO ACCOMODATE POOR BAND CONDITIONS AND ALSO SUPPORT SIMILAR ANTENNA TYPES.

USE OF END FEDS OR LONGWIRES AT THE PEOC OR EOC SHOULD BE AVOIDED AS THEY HAVE PROVEN MANY TIMES IN THE PAST SET’S TO BE INEFFECTIVE.

IN THE PAST FIVE YEARS I HAVE ONLY BEEN SUCCESSFUL IN CONTACTING THE EOC ONLY ONCE. THIS TELLS ME THE EMERGENCY READINESS OF THE PROVICIAL EOC AND NCS STATION TO BE LACKING. THIS IS PLANNING FOR FAILURE.

LIKE IT OR NOT THE PROVINCE NEEDS TO BE SERIOUS ABOUT ARES PRIOR TO ANY REAL EMERGENCYAS WELL AS THE ARES LEADERSHIP AT RAC.

Icom 705 Portable Radio – Top Ten Review

Here is what I like about the Icom 705 after spending a bit of time with it.

This radio is not for everyone and one may prefer a lower cost FT-817/818 or higher cost KX2/3. What is your use case for it?

It is a perfect shack-in-bag radio

It is not a mobile radio but can be used as one

It is not a handheld radio to wear on your belt

It is not a beach radio as you will find that sand will scratch the display eventually

It is not a Field Day radio unless you are in the QRP battery category

It  is the perfect shelf, bedside or desktop radio in a home office

It has DStar which is the best digital mode going these days and simple to use

First thing is to install and format the SD card (max 32GB)

Then execute the software updates

Then load the memories using the CS-705 software. I did my file in advance so it was easy to get it all set up the same day. I broke out my memories in groups HF, 6m, 2m, 70cm and Dstar

My Icom 705 Use cases:

Owning Icom’s biggest handheld since the Icom 32AT

Portable radio for SOTA and POTA

IF for a SG Labs 1296 and 222 transverter and future 10 GHz radio

Ok Top Ten Likes

  1. Operates just like a 7300 and 9700 so learning curve is simple
  2. Huge Display
  3. The display is readable outdoors in sunlight
  4. TX Delay available for each band so useful with Transverters
  5. Great battery life (expect more with the new high capacity battery)
  6. USB port for rig control (If I choose to but there are smartphone apps to use)
  7. Excellent SW receiver
  8. SD card for voice and cw memory
  9. USB port for battery charging
  10. Excellent audio

OK Dislikes

  1. Huge Display – Its going to get whacked at one point in the field
  2. USB port for battery charging – takes 3 hours
  3. W-LAN is 2.4GHz not 5Ghz
  4. LC-192 is small at 10×14 inches but I haven’t seen one in person yet
  5. Price – yeah its expensive but then this is a very feature rich radio with no others to compare too

Right now until I get to see the backpack I have 3 carrying options:

Topo Design Camera cube

Lowe Pro camera bag

Think Tank Camera Backpack – closest to the LC192 and I can add a side stiffener for the antenna

Pelican Box

The Yaesu FT-817 whip works great with the radio with the simple addition of a elbow BNC connector

 

I will say one thing and hopefully over time I change my point of view but the radio is a box that lies on its back. We have solved the problem with tripods, stands (I think I am going to hack out my Windcamp 817 stand) and using a wooden I used with my KX3. I really really prefer the Icom 703 and FT-817 form factor as it slides easily into my Think Tank Commuter bag. This boxy radio will expose its screen that could get bumped or damaged. We will have to see what happens after people actually take the radio outdoors. We all know the KX3 can get dust and sand inside.

I knicked my 7300 display so I am sure I can do it again on a field radio. That’s why I prefer the 7200 for outdoors. Its rugged and designed for that usage and the top is spill proof where the 7300 has openings for a soda to spill into and fry it up quick.

 

 

 

How the Navy SEALs wound up buying 450 counterfeit radio antennas

How the Navy SEALs wound up buying 450 counterfeit radio antennas

Danger ahead.
By Justin Rohrlich

Geopolitics reporter

Last spring, the Pentagon spent more than $165,000 on a set of sophisticated radio antennas for a contingent of elite Navy SEALs. Unfortunately, they were cheap knockoffs, courtesy of a California vendor apparently looking to secure some extra profit.

search warrant application recently filed by the Defense Department provides a glimpse into how the alleged scam worked.

In April 2019, the Naval Special Warfare Command solicited bids to buy 450 VHF/UHF antennas for use by members of the Navy SEALs. The request required the body-worn antennas come from New York-based manufacturer Mastodon Design, and that the supplier qualify as a small business.

The government used to purchase the antennas directly from Mastodon. However, it no longer could because after Mastodon’s sale to a large multinational defense contractor, the once-boutique company no longer qualified as a small business. This meant the Navy would have to buy Mastodon’s antennas through an authorized small distributor or reseller.

On May 1, the sales team at Mastodon got an email from the procurement department of a California company called Vizocom. It said the company was bidding on a Navy contract and wanted to know how much 450 Mastodon antennas would cost. Mastodon quoted a price: $165,109.50.

Vizocom then submitted its bid to the Navy for the exact same amount. A source with direct knowledge of the situation told Quartz it was highly unusual that Vizocom wouldn’t want to make any money on the deal. At this price, the Navy awarded Vizocom the contract.

The company, however, would never actually place the order with Mastodon. Instead, it would import low-cost antennas from China and pass them off as from Mastodon using fake serial numbers and spec sheets, according to the search warrant application and sources with knowledge of the deal.

The Navy realized something was amiss when it distributed the antennas to the SEALs who would be using them in the field. Vizocom’s antennas “differed physically” from the Mastodon antennas they had used before and “were of poorer quality,” says the search warrant application.

Investigators eventually discovered a purchase order issued to Alpha Antenna by Vizocom that requested testing, packaging, and shipping to the Navy 450 antennas for just $12,208.50. Alpha seemed to be an unwitting participant in the alleged Vizocom scam, according to a source close to the case.

“The use of these so-called middlemen who don’t manufacture anything, they just order it from someone else that does manufacture it, can be a problem,” Neil Gordon, an attorney who oversees the contractor misconduct database at the Project on Government Oversight, a nonprofit government watchdog, told Quartz. “The longer the supply chain, the more difficult it is to keep watch over it.”

Despite these kinds of problems plaguing the US armed forces, under US president Donald Trump, the Justice Department has prosecuted fewer of these types of cases, Gordon said. Cutting down on procurement fraud prosecutions against businesses became a DOJ policy goal in early 2018 in an attempt to, among other things, “preserve limited resources.” The department has managed to dismiss 34 of 36 such cases since then. (US attorney general William Barr, the nation’s top cop, has called the False Claims Act an “abomination.”)

The Justice Department still managed to claw back more than $3 billion in settlements and judgments involving fraud and false claims by federal contractors during the government’s 2019 fiscal year, which ended Oct. 1, 2018. And just this week, US Technologies, a New Jersey electronics supplier, agreed to pay $525,000 to settle allegations that it sold the military dozens of faulty circuit card assemblies—some of which were counterfeit—destined for a US Air Force weapons system.

As for Vizocom, it has earned more than $30 million from US government sales since 2016, per an official government spending database. The Navy has accounted for about 15% of its business, with the Army, Air Force, Coast Guard, and Department of State making up the balance.

“Vizocom’s vision is to succeed in its goal to bring about a better world, thru making technological advancement to give all people access to a better life,” its website says. “We believe we can only make this happen by upholding genuine universal values we all cherish on a daily basis and in all stages of like [sic]…We work as a team and deal with others with integrity, we deliver service excellence, and we seek success by working hard hand in hand in an open collaborative professional environment with our staff, our customers, as well as our vendors and suppliers. We build capacity by seeing the goodness in people. We build trust by trusting first.”

If the company’s mission, misspellings and all, didn’t raise eyebrows among investigators, its headquarters sure did. The company says it is located on the third floor of a 20-story skyscraper in downtown San Diego. In reality, its physical footprint is little more than a mailbox in a shared virtual office space. Vizocom is actually located at the El Cajon, California address the company had on file with the federal government. When investigators paid it a visit, they found a small single-family home occupied by Vizocom’s owner.

Authorities searched the house just before Christmas, seizing 49 antennas and assorted electronics, expecting to find evidence of wire fraud, among other federal crimes, as well as communications between Vizocom and its own suppliers that may yet help to untangle the rest of the case.

“What a brazen criminal act that could have potentially contributed to the loss of life of some of our SEALs who are placing themselves in extremely risky situations,” former FBI agent Dennis Franks told Quartz. “It is horrendous that greed on the part of a few individuals could create a situation in which the ability to communicate with other team members or command centers could be hampered and thereby prevent critical information from being sent or received.”

Mastodon filed a civil lawsuit against Vizocom. And after Vizocom agreed to abide by a judge’s injunction, the two companies settled their case at the end of November. The investigation into Vizocom is ongoing, and no official charges have been filed as of yet. Neither representatives from the Defense Department nor Vizocom responded to requests for comment.

The military renaissance in high frequency communications

The military renaissance in high frequency communications

LONDON — Special operations commands across Europe are ramping up their capabilities with high-frequency communications to ensure connectivity on the battlefield. Leaders there are turning to high frequency communications as a way to optimize properties that provide a low probability of interception and detection.

Special forces in France, Germany, Poland and Ukraine continue to receive high-frequency, or HF, systems as a way to diversify communications plans, industry sources confirmed to C4ISRNET.

Some special operations organizations have selected L3Harris’ AN/PRC-160(V), industry sources said.

Enhancements in HF come at a time when NATO members and partner forces are suffering from a disruption of satellite communications, particularly along the alliance’s eastern flank where Russian armed forces continue to conduct electronic warfare.

In an online presentation to the Association of Old Crows on Aug. 6, Paul Denisowski, product management engineer at Rohde and Schwarz North America, described how communications satellites are vulnerable to antisatellite systems as well as ground-, air- and space-based “kill vehicles.”

“China, Russia and the U.S. have all carried out ASAT tests and many other countries are developing ASAT capabilities,” Denisowski said, using an acronym for anti-satellite. To boost resilience, some commands are turning to high-frequency communications.

During the presentations “Lost Art of HF” and the “Rebirth of Shortwave in a Digital World,” Denisowski explained that HF is making a comeback in local and global communications. This renaissance comes as the result of improvements in a range of fields, including antenna design, digital modulation schemes and improved understanding of propagation.

The market is also helped by reductions in size, weight and power requirements as well as the introduction of wideband data, enhanced encryption algorithms and interoperability with legacy HF sets, he said.

“This means end users are now benefiting from easier-to-use and cheaper solutions featuring improved data performance, audio quality, availability and operation. And because of a lack of infrastructure, HF is less expensive and relatively robust, although solar events may temporarily disrupt HF communications,” he said. Specific upgrades include “Adaptive HF,” which comprises automatic selection of frequency and the establishment of communication through automatic link establishment, or ALE, technology.

The latest technology of its type — 4G ALE — is capable of supporting wideband HF communications, or WBHF for short, providing end users with the ability to “negotiate bandwidth, modulation type, error correction and the number of sub-carriers,” Denisowski explained.

“ALE selects frequencies using link quality analysis, which allows it to listen and determine if a channel is in use and adapt if conditions change,” he said.

He added that HF can now support data rates up to 240 kilobytes per second on a 48-kilohertz channel, particularly useful for more robust communications in hostile environments.

“WBHF has already [been] used in military trials. It’s a technology which is most definitely here and now,” Denisowski said.

Similar sentiments from Europe were expressed to C4ISRNET, where armed forces continue to integrate HF technologies into existing and future communications plans. Examples include Germany’s Ministry of Defence, which is deciding whether to include an HF requirement as part of its wider Digital Land Based Operations communications program.

According to a report by JK Defence and Security, a partner of L3Harris Technologies in Germany, HF communications comprise a viable alternative to satellite communications tech available to European NATO partners.

The report explained how the U.S. Army and European NATO partners explored such scenarios during a series of joint exercises in 2019 and 2020. “A new need arrives for alternative communication skills, justified through the increasing vulnerability from SATCOM jamming as well as the potential failure of SATCOM as a result of attacks on spacecraft or through the use of anti-satellite surface-to-air missiles,” the report’s author, Jan Pätzold, told C4ISRNET. “The development of alternative skills is important to reduce dependence on SATCOM.”

According to Pätzold, so-called Skywave HF, which bounces signals off the ionosphere, enables beyond line-of-sight communications across “thousands of kilometers” without requirements. HF communications is also ideally suited to supporting local network coverage. “This offers advantages over SATCOM in urban areas, but also in mountainous areas or far north latitudes where no line of sight to existing satellites is possible,” Pätzold said

Trying the new ISS FM repeater. It is QRV!

I couldn’t wait to try the new ISS FM repeater myself.

ISS FM repeater information

Downlink: 437.800 +/- doppler

Uplink: 145.990 (67hz PL Tone)

Download ISS Tracker to know when the ISS is overhead   At night you can see it with binoculars move across the sky
Put the uplink in a memory channel and then add more memories to cover the downlink with plus or minus for doppler
I would make it every 2.5 or 5khz       so start at 437.750 to 473.800
Use split mode on the VFOs or memory channels so you always transmit on input and then receive on the output
As the satellite passes over , the frequency will shift and you just follow the shift by cycling through memory channels.
Most often a Arrow Satellite Yagi will be needed and one hand is needed to arc the antenna cross the satellite passes. Keep contacts really short and allow others to use it as well.
