SDR Console transmit audio bandwidth limited to around 5 kHz
The stuff I did in the early 70s was very mild digital redundancy encoding on digital audio with frequency hopping about 7000 times a second. CDMA did not figure into it in those days. We spread the s

Simon's Worldmap - A question on sunset countdown time
If you had taken a deep dive I was wondering if a couple other factors made a significant difference. The part below I had gotten quickly, more or less. (Muslim prayer times is in there somewhere.) Fo

Ah I didn't know if you'd been rabbitholed by this issue before and looked into it far deeper than is reasonable. I'm curious but for the TL:DR level. {^_-} On 20221213 11:53:50, Ken Sejkora wrote:

What is the TX output power on your Hermes board? I thought they were +33 dBm. If that is the case and the loop back path includes no attenuation you may be overdriving the RX. {o.o} On 20221212 06:51

I believe there are two paths that mic/line input can loop back to the output without going through applications. I suspect you have this right, though. {o.o} On 20221212 04:19:18, sm6fhz wrote:

Pluto: Interrupted transmit, usage via network

The switch does not matter. The Pluto is a USB 2 device that falls down to 100 M Ethernet. That means you must use the lower Pluto sample rates. Your tiny images are unreadable so how about trying ful
