I thought I would try VP8SGI this evening on 40M, since I had not tried 40 due to the horrible DQRM almost every night on their TX frequency. They were pretty loud tonight here in NTx (10-15 dB above noise floor). I use a Delta Loop at 50 feet. A DQRM was "almost" zero beat on their frequency and 20 to 30 dB louder than them, making it near impossible to copy them. And to top it off, there were also a few signals very near their Tx frequency also. I cranked the K3 filter down as far as it would go (50Hz) and tuned the VFO A just ever so slightly to maximize the SGI copy and throw a few dB more rejection on the DQRM. After a few seconds, I could copy him clearly to make the contact.
This was the first time I have had to use that much filtering to make a contact! ----- Roger W5RDW -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-in-Very-Heavy-DQRM-on-40M-CW-tp7613568.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
