Lots of SSTV now on 27700 USB, posting it to the HFU Discord: https://discord.gg/hfunderground
The receiver was the W3HFU KiwiSDR (I also tried the Northwest Ireland KiwiSDR and got the same results), my sound card is the Sound Blaster Audigy Rx, the audio source is set to “what u hear” (the program will hear whatever is playing through the computer),
It's making a barber-pole pattern on the waterfall. Is there something wrong with the modulation, or is it on top of some digital ute? I've seen a pattern like that before.
Also, I have this issue, I have the load all the way down to 0 and anything slightly above that the output drops significantly. I have a 1.1 swr on my vertical antenna. Also, at this low load setting the tubes glow, they glow harder when I set it higher. Do you know how I can get it to where the tubes are not glowing and the power is not lost due to a tuning mismatch? I am operating at 6920 khz and the band setting is set to 40 meters.
How well would a CB type amplifier work on bands such as 15/20 meters? Talking about the standard Texas Star/RM Italy type. I'm wanting to buy a Xiegu G90 and it would be nice to be able to use it mobile here and there.
