FM Free Radio / Re: FM Dxing equipment?
« on: October 31, 2022, 2228 UTC »
Aside from SDR and good antennas. It is very important to be able to have fine tuning and narrow filters. I use a YAMAHA T-85 tuner with 4 filter bandwidths.

Nice signals on 4185 and 5185

Nice signal and audio ION.

2030 S9 + Listening in SAM in SDR at 10Kc audio.

At one point a fuse blew lol. I replaced it and the TX worked fine. I turned up the modulation loudness even more.
Thanks for tuning in and your posts, song logs, fine audio comments and emails. I am only running 150 watts of AM carrier.

Nice signal S9+10 on the Drake R8B in SAM with preamp off

Started listening to RMI after Ballsmacker shut down at 0245 UTC
RMI had usual potent signal (S9+20 55545) and 10 kHz of audio, but at 0255 signal made a dramatic fade to near zero. When signal came back it was much weaker than before and at 0321 UTC signal is averaging S5-S6 with a 34433. Either the band went long or a possible flare with a K Index of 6 that was expected, just hit. The upper half of the audio above 5 kHz is getting lost in the noise.

I noticed the band went long as our signal is S7 in parts Europe. I also noticed the fast change in the band which could be the flare also. We will stay on for a while.

Thank you again for tuning into MRI.

Got any Parliament/Funkadelic or Jimmy Castor's classic early 70's stuff?

If I do not have them I will download it. Great stuff. Let me know of any other songs you like also.

I implemented some improvements on the SSB transmitter. From all of your great comments. It went well. Thanks for all of the fantastic reports.

I have used LMR cable in the past. The newer cheaper brand cables are working just as good.

Hello Redhat. I have you at a S9 to +10 in SAM on the R390A. A higher static level tonight.

I listen to XM radio on a very small portable with a built in FM part 15 transmitter to play on the car FM radio. I had it for about 10 years now. It has a lifetime free subscription. The quality of the audio is OK for the car but not as good as a 128K internet radio stream. I listen to comercial free XM music stations. I can’t stand listening to comercial FM radio anymore.
