But using a high-pass filter on the audio passband is fairly common with FM transceivers. Most repeaters do not transmit their CTCSS tones. Some do. And in some cases the CTCSS tone transmitted by the repeater is not the one necessary to open the squelch on the repeater's receiver. On some FM receivers a CTCSS tone is obvious, especially the ones higher in frequency. So, yes, Flex could make a tracking audio notch filter but that is quite unusual. In the mean time, have you tried using the 10-band EQ? ;-) -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/

Yes, I know that is a hack but it might make it tolerable. No I have not. It likely would work. However I think a "Flex" could do better then that. It only should filter out the particular PL tone rather then a large frequency range to maintain quality base tone reproduction. Also I don't like to having to use different receive profiles for FM repeaters with and without PL tones. It becomes messy at best. It would also give Flex an edge up in clarity. I don't think it would be hard to implement.

Re: [Flexradio] U/V sub-audible tone problem
Gentlemen, Out of respect for Flex Radio's quality I fasten one of my "retired Hi Fi" systems to the 5000A so I can hear below 40 Hz and any carrier noise is quite apparent (which also makes it easier to compensate for my age-related hearing decline) and noticed this on one of the local repeaters. I made several nasty comments during QSOs with others and, magically, the problem went away. Of course, that is only my solution to one special problem. Is this limited to only one CTCSS tone? More than one repeater? I live where I have to contend with three tones. 73 Lee K9WRU - Original Message - From: "Dave Beumer WØDHB" To: "'John Vandenberg'" ; Sent: Friday, September 21, 2012 10:49 PM Subject: Re: [Flexradio] U/V sub-audible tone problem John I've never noticed the issue here, I do a lot of SAT work with SO-50 which uses 67Hz.
