Re: 49:1 EFHW Antenna Kit
One way to add 80M to a 40M EFHW without changing 40M and up, and without making the antenna twice as long is to add a loading coil and a short length of wire that tunes 80 meters. This coil effectively cuts off the extra section on 40 and up. You can find examples of this in other EFHW product lines like the PAR Endfedz JR models at Vibroplex. The bandwidth on 80 is not as wide, but the antenna is a much more convenient overall length. There are also other techniques?such as stubs to allow tuning individual bands. The limit on frequency range will be the transformer core and winding schedule which may increase losses and lower power capacity. 73 de w6akb

Re: 49:1 EFHW Antenna Kit
Will,
The design allows for using whatever length wire you would like so I would say try it out!?

Re: Build-a-Pi only once?
I wonder if there is value to putting a choice to delete the download/install directories if the install script sees the directory for a future update?
That way if someone has an issue, reinstalling and having the script delete the directories on command from the user will aid the user that does not have experience in the command line interface.
Just thinking out loud :D?

Re: 49:1 EFHW Antenna Kit
I was looking into this kit but would like the option of a longer wire to see if 80m would be feasible.
80M would be possible with a longer wire (~132') but may cause the SWR on some of the other bands to exceed 2:1. --

Re: Problem with PAT and Direwolf
Edit your axports file and remove all but one of the wl2k entries and don't leave any blank lines at the end of the file. In the direwolf.conf file, comment out or remove the line you added. Then uncomment one of the lines #PTT Rig 2 localhost:4532 so it reads PTT Rig 2 localhost:4532 This will send the PTT commands to FLRIG. FLRIG should be open and configured before you attempt a Winlink connection. --

Thanks for the tip Jason.
FLdigi is installed!
I left BAP as it was and just implemented the commands you suggested.
Now I need to rig up my sound card and serial connection to talk to the Pi and see if I can get it all to operate.

Just remember that BAP is always going to show you need an update for FLDIGI. Don't try to update FLDIGI through BAP.
And I used BAP on my Pi-zero, Jason, with no problems, but I only loaded a very few programs with it.
Something things may load and work as expected. Others like FLDIGI may have a suitable workaround. My only point was BAP wasn't designed to be run on the zero. I don't discourage experimenting as each operator's needs are different. --

Hi Vic Very simple: sudo apt install fldigi
It installed and runs. Now I have to figure out how to extend the zero's USB ports so I have at lease 2 to connect my KX3 Sound Card and Serial link. By the way, I've had a go at overclocking the zero -- and it works well and speeds up the operations. Its only a minor overclock and again is easy to do and remove. You need to edit one text file and reboot -- and that's it! I used arm freq of 1100 and gpu freq of 550. I found a small heatsink to fix to the zero. I'm running? 'Conky' and the max temp with FLrig and FLdigi running is 47c -- which is well below the max I would consider operating.
Code:?
sudo nano /boot/config.txt
Then add in the file:
Code:?
arm_freq=1085
#arm_freq=1095 for my other unit with heatsink
gpu_freq=530
#gpu_freq=550 for the unit with a heatsink.
over_voltage=2
core_freq=515
sdram_freq=533
over_voltage_sdram=1

What commands allowed Fldigi to load on the Pi-zero, Bruce? I would be interested in doing that on mine. And I used BAP on my Pi-zero, Jason, with no problems, but I only loaded a very few programs with it.

He apparently downloaded once, but something happened in the install and says he could not download it again.

You only download it once and install what you want. After that, use the Build a Pi update tool to install additional apps. --

Have a ham friend who downloaded Build-a-Pi and was doing it wirelessly, which I have done at three times.
But now he says he cannot download BAP again. Supposedly he could only do it once.
I have never heard of this issue. Am I missing something or has he had some unrecoverable error?

KM4ACK EFHW Antenna....my results
A few early examples...I've just got everything radio/computerwise going.
On SSB, I worked a NH station on 5W.
On FT8: Antofagasta, Chile 4577 mi. Also worked PR and Cuba
Right now it's set up in the back yard with the end up at 41 ft on a jackite fiberglass pole. It runs generally N-S with the pole on the N end. I'm looking forward to some POTA adventures.
Great little antenna, Jason.

Re: I think I have tried everything, but maybe not. Help!
Thanks, everyone for all your help.
My thought is that my 7" Pi screen is what is giving off the RFI that is keeping the dongle from working. I was testing all day yesterday (different HDMI cables; ferrite beads on the HDMI cables and everything; no buck converter=straight AC to Pi PowerSupply). The reason I think it is the screen or it's HDMI outputt is that it knocks out my GPS on my Yaesu FTM300d when it gets too close. I took the pi/screen out of my go box and my 300d GPS came back on; brought the pi/screen towards the 300d and the GPS went away. LOL. If I wasn't bald, I would have pulled all my hair out.
@ Jason. Thanks so much for that resource; I am gonna check it out tonight. I am going to try running without a monitor (is that what some people calle headless) and use VNC.?
@ Marty and Ben. Thanks. I did get an extender, put it on left the thing on all night long six feet away from the Pi; no luck.
@ Curt. Thanks. Those are the dongles I have as well.
@ icrewu60s. Thanks, I didn't even know that was a possibility. I will have to give that a chance before anything else. So many great videos to watch; so little time. LOL!

Pat Winlink Forms - Question, or possibly a eature request
#pat-mail
So I have a very recent, new installation of Build-a-Pi on a Raspberrypi 4.? Everything that I have touched so far has worked VERY well.? Well done KM4ACK!!
I have spent the most time with Pat Menu as my "Linux only" shack has kept me from success with Winlink (used for our local ARES group).?
I noticed that you can schedule a daily update of gateway stations - is it possible to schedule a regular check/update of the latest version of the standard forms? (ICS form tend to get updated on a fairly frequent basis, and using older version of those forms can cause problems for the recipients).
This would be very handy feature for ARES form work.
Thanks again for all of the development so far.
