I’m pondering options and I’ll follow your progress with interest. I’ve used WSPR and WSJT modes for vhf dx in the past. Generally I used a signalink between a radio and a PC or laptop. The radios used have been FT817 and IC703.
If your radio has an inbuilt “sound card” the computer can connect direct to that and use that as the interface to the radio.
Andrew, I have the exact same RPi setup as you. I had hoped to use it last week on my 1st SOTA activation but I totally forgot to change my Pi case to one where I could route my jumper cables to power the Pi off of my battery. Didn’t have a good screwdriver to take apart the case, so no joy! I know the setup works as I have made 1 FT8 contact at home using this setup with my 891, so there is no reason to think it won’t work in the field. Go for it! PS. check out OH8STN for his web page and YouTube channel, as well as KM4ACK. They’ve got tons of stuff and OH8STN’s battery packs are what I have made.
Hi, all. Sorry it’s been a while but I’ve been trying to resolve a lot of issues but finally have what I believe to be a working setup as you can see below from when I was testing it out for Parks on the Air (POTA).
Raspberry Pi 4
Sunfounder 13.3 in HDMI Monitor
Roccat Juke Sound Card
GPS Dongle VK172
Chameleon MPAS 2 Vertical or Emcomm 3 Portable
Power: Between 37 and 61 Watts
I am working on setting up the Xiegu X5105 in place of the FT-891 for the longer hikes when I’m doing digital on an Activation. I definitely want to add an FT8 as a mode. Hopefully operating from a summit may allow me to get contacts quicker than FT8 and POTA.
Looking forward to any additional tips you guys have. Looking at W1/HA-001 on 9/5/2020 for my next Activation. Planning on taking the Auto Road since I’m too out of shape after Monadnock.
