Andy, LF, I have had no problems with the serial port PTT control of WSPR. With a normal 9-pin RS232 port, on the motherboard of the PC, I use the RTS line for PTT switching, via a simple transistor
I've just re-started the WSPR monitoring, at 12:00z Will keep an eye on the display over the afternoon, when in/around the shack, and upload all spots to WSPRnet Cheers, John
Hi LF, My thanks to all who uploaded reports of my WSPR transmission to the Spots Page. I was testing a new mixer for my linear transverter project. Probably try some more demanding mode soon. Also n
Hello Jim, LF Group as i have mentioned on the chat/sked wsprnet page i left my rx setup running overnight this is a list of your wspr beacon decoding 2226 -20 0.6 0.503504 0 M0BMU IO91 30 2232 -17 0
I have (sort-of) sorted out the transmitter control problem. While both WSPR.EXE and WSJT6 both refuse to properly control the PC-installed COM1 port, they do both behave properly with an FTDI type U
Not at this turn but soon I'll have a dedicated 500KHz air core loop + tube pre-amp + Kachina 505DSP with 200Hz brickwall filter + WSPR enabled PC (GPS time locked). I will left this instalation runn
Dear Mark, LF Group, Thanks for the reports - Interestingly sometimes I am seeing an extra faint trace from Jim, almost exactly 100Hz up and it even decoded on one over. It is much weaker (at least 1
