The booster will allow more run time and better radio efficiency as 13.8 volts plus or minus 15% is the range
Oh Oh my radio just shut off yeah the voltage dropped below 12 volts at 20a draw and the radio shut off. yes that is normal
buy the booster and go make 100 watt QSO for a few hours at the park or emcomm site

I typically use 20w or 50 watts in the field so my Bioenno battery lasts longer or I can choose from my 9a, 12a or 18a version depending on how long I am out there

I had a chance to meet up with Peter VE3VGS for some field ops. I wanted to see his voltage Booster from West Mountain Radio and his battery setup.
I brought my FT-817 go bag and my Icom 705 backpack with a PackTenna mini EFHW cut for 20m
While Peter was setting up his antenna and station wires I threw a water bottle with some para cord in a tree, connected 25 ft of RG174 cable to the FT817 and replied back to KD2JQK Steven in NJ calling CQ on 20m while I set up the 705 on 6m using a base loaded whip
We had a a nice 20 minute QSO chatting about Hockey and he was banging in at 59+20
Peter ran a long wire fed with a home made balloon and when he swapped antennas the PackTenna was several units higher so Peter figures he has a bad balun or the antenna was right for 20m. His antenna as an inverted V fed at the end is more of a NVIS which doesnt do anything on 20m. The radiation angle may have been too high to bounce off towards Belvidre, NJ. Experimentation, Experimentation and location
The park was in a valley so just to show you DX is DX wherever and whenever so just throw a wire up and go QSO
I ran out and bought a West Mountain PwrIso for my Power box and will add the Voltage Booster when they are back in stock to complete my scenario for a HIGH Power set up for my FT-891 and external AGM Battery . QRpers do not have to spend this kind of money these days hihi
So arrive and on air in 10 minutes, 20 min qso and Peter still was not ready to transmit yet!
Rapid deployment Ham Radio rules!
I finally got to work the USS Hornet ARC this weekend after being on board years ago. The station was not in operation as no members were present but the tour of the ship was awesome.
So I am ecstatic to finally work these guys. However, I did it on CW on 20m
No FT8 folks ….sorry
Changes from Version 1.24- When in the Center mode of the Spectrum scope screen, the REF level setting does not reflect the scope waveform during transmission.- This firmware update version 1.26 has been improved, so it will not reset settings and memories.If the firmware is updated from version 1.24 or earlier, the settings and memories are not reset. However, if the firmware is reverted to 1.26 from a later version (after 1.26), the settings and memories may be reset.
You cannot revert to firmware version 1.24 or earlier on the serial numbers listed below, which have firmware version 1.26 or later installed.IC-705 #32: Serial number 32001001 or later
IC-705 #33: Serial number 33001001 or later
IC-705-T #36: Serial number 36001001 or later
IC-705 #37: Serial number 37001001 or later
Please note on the models listed above, if you revert to firmware version 1.24 or earlier, the audio will not be correctly output.
The CS-705 programming software used with this firmware can be downloaded here.
To update the firmware1. Download and unzip the firmware data (for example, 705E126.dat) and copy it into the “IC-705” folder that is on your microSD card.
2. Insert the microSD card with the firmware data into the transceiver.

3-1. Display the SD CARD screen in the Menu.
3-2. Touch “Firmware Update” on the SD CARD screen to open the FIRMWARE UPDATE screen.
3-3. Touch [▼] to scroll to the end of the screen to read all the precautions, after you read and agree with all the precautions, touch [YES].
3-4. The confirmation dialog recommends making a backup of the settings and memories, touch [YES]. We recommend that you make a backup of them in this step, because all the settings and memories may be reset after updating the firmware.
3-5. After the backup file is made, and the firmware selection screen is displayed, touch the firmware update data (for example, 705E126).
3-6. Please carefully read all the precautions, and when you want to execute it, touch [Yes] for 1 second to start the firmware update.
3-7. When the update is completed, “Firmware updating has completed.” is displayed, and the transceiver will automatically restart.If the setting data needs to be converted, it may take some time to restart.

For those working hard on their Basic and Advanced ham exams, please be aware that i doing testing remote via Zoom
No need to wait for in-person testing when we can do it NOW!
Get on the air NOW!
contact me at ve3ips@gmail.com
I have done many for those taking the RAC courses
Thanks to Tom NS6T
Super useful for your 3 element Yagi but also beneficial with a rotatable 40m dipole
