Yaesu FT-5D vs FT-3D Why Buy?

Thanks Yaesu for another shiny hand held that we can spend our Covid savings on


The FT3D has been discontinued and is no longer available, but what makes the new FT5D different from the FT 3D?

The design has a more colorful impression. The size is almost unchanged. 

The main body has the following two strengthening points.
・ Improved waterproofness FT3D IPX5 equivalent → FT5D IPX7 equivalent
・ Speaker volume improvement. Built-in speaker FT3D 700mW → FT5D 1000mW (1W). External SP terminal FT3D 300mW → FT5D 500mW.

Other newly added functions

[Touch & Go operation] by activity monitor (new function) (convenient for simultaneous monitoring of air band )

◆ PMG (primary memory group activity monitor ) function
Register frequently used frequencies and press the [PMG] key. only registered with the state (signal intensity) of the frequency display (bar graph up to five channels)
moving instantly to that channel by simply touching the bar graph

◆ CAM (CH activity monitor) function 

It is possible to register frequencies (memory channels ) frequently used by friends in the CAM group and operate while monitoring the status (signal strength) of each channel with a bar graph . Instantly move to that channel by simply touching the bar graph

◆ Dual LED indicator FT3D has one indicator
◆ The character color of the band to be operated can be switched between white / blue / red
◆ Full-scale robust and shock-resistant structure equipped with a rubber protector
★ New equipment (included) Quick release holster (SHB-26) standard equipment

How to identify junkbox cores ferrite materials :-) G8JNJ

How to identify junkbox cores ferrite materials 🙂

G8JNJ: Baluns and Tuners:


The easiest way to identify most ferrite materials is to wind about four turns of wire through the core and then measure the lowest frequency at which the value of reactive impedance equal resistive impedance i.e. X=R. There will be some variation between different batches and sizes of materials. But if you can plot the results graphically you can easily identify the  ‘signature’ of each material.

Here are my references for some common ferrite materials

FT240-77   0.74MHz
FT240-31   3.5MHz
FT100-33      7MHz
FT240-43     17MHz
FT240-K      22MHz
FT240-52     31MHz
FT240-61     58MHz

Iron powder has a slightly different ‘signature’ it usually has a very low resistive component, which peaks to a higher value near self resonance. The more lossy the material the broader and lower value of resistive peak is apparent.

T200-52     40MHz   Lime Green (& Blue or Red) colour common in PC switch mode power supplies – moderate loss
T200-26     60MHz   Yellow & White colour common in PC switch mode power supplies – high loss
T200-2       60MHz   Dark Red colour used for HF tuned circuits (& Ruthoff Ununs) – high Q low loss
T200-1       70MHz   Blue colour not common – moderate loss
T200-6     100MHz   Yellow colour used for VHF tuned circuits – high Q low loss

6×6 Field Ops 6m by 6m by 59

I ran the FT817 on 52.525 FM with a park to park operation with Yury VA3GKX and Edwin VE3ZXN at a distance of 17km and 20km

The antenna was a Vince VZB 6m EFHW antenna up about 30 feet. I also had a dipole but the vertical was 3 S units better

Edwin was in a parking lot so thats just like a park

Peter VE3VGS also ran his FT891 at 100 watts using his long wire 9:1 antenna not visible in the picture

57 signals all around with Yury using a Rhombic at 59 plus with higher power and Edwin with a mobile set up with a mag mount antenna

Get out and Simplex on 6m

Kabul Radios

A recent read of the various newspapers are showing

A Datron PRC1077 radio supplied to the Afghan army, and another shows what appears to be a Harris tactical hand-held radio, though the blurred image could also be a cheap push-to-talk radio like a Baofeng.

The U.S has provided nearly 2,667 Harris RF-7850M-HH radios to the Afghan military, according to CDR. Patrick L. Evans, a spokesperson for the Defense Security Cooperation Agency.

The Afghan National Security Forces specifically use the PRC-1077, a tactical radio man pack transceiver designed for short range two-way communication, and the OE-254 antenna. The radio and antenna training provides the ANA with the ability to communicate more proficiently across the battlefield.

OE-254/GRC - RadioNerds
Comics on and about antennas?

Many of these radios have found themselves being used by the Taliban Army

The Taliban has made very good use of tactical radios and cell phones to co-ordinate their missions ending in Kabul on the weekend.

Key U.S.-Funded Communications Equipment for the Afghan National Defense and Security Forces (ANDSF)
According to Department of Defense (DOD) data, the United States funded about 163,000 key
communications equipment items for the ANDSF in fiscal years 2003 through 2016 (see table2).

• The majority of the key communications equipment was tactical radios, which include the high frequency, very high frequency, ultra high frequency, super high frequency, and
multiband radios.
• About 88 percent of all the key communications equipment items were authorized for procurement by DOD in fiscal years 2003 through 2011.
• About 97 percent of the radios included in DOD’s data were manufactured by Harris, Datron, Motorola, or Codan.

Table 2: Quantities and Examples of Key U.S.-Funded Communications Equipment for the Afghan National
Defense and Security Forces, Fiscal Years 2003–2016

Category Quantity Examples

Very high frequency radios 75,256 Datron PRC-1070 handheld, Datron PRC-1077 vehicle-mounted, Datron HH7700 handheld

Nontactical radios 66,439 Motorola GM360, Codan NGT SRx, Universal Radio AR-8200 Mark III

High frequency radios 13,464 Codan 2110 manpack, Datron RT-7000 base station

Multiband radios 5,377 Harris RF-5800M base station, Harris RF-7850M vehicle-mounted

Ultra and super high frequency radios 2,107 Harris RF-7800W vehicle-mounted, EF Johnson APCO-25 handheld

Total 162,643

Source: GAO analysis of Department of Defense (DOD) data. | GAO-17-667R
Notes: The time frame covered by this table refers to the fiscal years in which DOD authorized the equipment for

Included in the table are 497 high frequency radios and 1,528 very high frequency radios that were authorized in
fiscal years 2003 and 2004 using a combination of Foreign Military Financing and international donations, according
to DOD data. Those data did not indicate how many of those radios were funded by international donations. The
remaining equipment in this category and the other categories was reported as being funded using only U.S. funds.
High frequency radios operate in the 3–30 megahertz frequency range, very high frequency radios operate in the 30–
300 megahertz range, ultra high frequency radios operate in the 300–3,000 megahertz range, and super high
frequency radios operate in the 3,000–30,000 megahertz range. Multiband radios can operate across more than one
of these frequency bands. The nontactical radios category includes commercially available handheld radios that are
not designed for use in combat.
According to DOD data, about 94,900 of the U.S.-funded communications equipment items
were for the Afghan National Army (ANA), and the remaining approximately 67,700 items were
for the Afghan National Police (ANP) in fiscal years 2003 through 2016 (see fig. 4).
• DOD data show that the ANA received 96 percent of the tactical radios and that the ANP
received 95 percent of the nontactical radios.
Page 10 GAO-17-667R Afghanistan Security
• According to a DOD communications equipment manual, the primary advantage of using
high frequency radios is their capability to provide long-range, over-the-horizon
communication. However, high frequency radios’ long-range capability makes their
communications susceptible to enemy interception.
• Very high frequency and ultra high frequency radios are normally limited to line-of-sight
communication, so their range is restricted, according to a DOD equipment manual. Very
high frequency radios are generally used in the military by combat and combat support
units while on the move. Ultra high frequency radios are generally used in the military for
ground-to-air communication. Super high frequency radios are used for radar
surveillance and satellite communications.
