Re: Low resource SDR Software

Hi Kevin, I have been playing with SDR radios for over 15 years. I am currently using a RTL SDR that looks like this: http://www.cnx-software.com/wp-content/uploads/2014/08/RTL-SDR_USB.jpg It tunes 100khz - 1.7ghz and runs fine on an old 2.4 ghz p4 machine with 1gb ddr ram and XP. I have tried most ...

Re: Aphex Compellor

Thank you for the comments bill, I want to try it out as a test Setup stereo link isn't all that important because I intend to use one of the 323's on my SW transmitter and the other on my.ham rig. I will use a 320a in stereo mode when I can get one... :)

Re: Aphex Compellor

Any body know of any compellor 320a's sitting around collecting dust? Unfortunately I didn't realize the 323 is a mono unit and I want to run stereo. Another 323 would do just fine and I'm always looking for non working units for spares.

Take a look at these Gates AGC/Limiters on Ebay this guy has been on here selling broadcast processors for a while.

Re: 80's AM loudness War

Although I have never seen a BL-40 in use at a station I have been watching some videos on youtube showing them in operation. I can honestly say from what I have seen and heard these boxes smash the audio! That's the way I like it dense and loud, There are several after market units based on the BL-...

WBMQ 630 AM Savannah GA

Whilst searching Youtube for "Abandoned transmitter sites" I found a video of the former WBMQ 630 transmitter shack complete with transmitters, processing gear, antenna monitor ect. It is sad that all this history has been laying around for over 22 years and it should be preserved in a museum :( You...
