I had WSPR and FT8 working well from my Windows 10 machine through my 7300 and then did a download and reset my parameters. All still seems to work well, receiving and transmitting messages, but I have no power going out. I have checked my SWR and it is good. I don't know whether my problem is in the computer with WSTJ or in the transceiver. No problem transmitting power in non-data mode. Any help or suggestions would be really appreciated. Thanks.
