Ah, so it might not be my lack of intellect or failure to read something that I should have! I proceed initially on the assumption that any trouble is me! Don't rush because of me! Nothing urgent. I can feed cats, plant flowers and do a multitude of other things. Let me say, though, that this is by far the most "sensitive" 2M radio I have. Absolutely wonderful!
Thanks for the feedback, Graham!

The software guys have the ball to figure out why the 300 Hz high pass is (apparently) not doing it's job. --- Graham == On Wed, May 18, 2011 at 3:41 PM, Lee Mushel <[email protected]> wrote: Ted, Graham, Please hurry and figure this out. That CTCSS tone is driving me nuts..... There must be some filter we have to turn on or adjust..... 73 Lee K9WRU ----- Original Message ----- From: "Graham Haddock" <[email protected]> To: "Ted Leonard" <[email protected]> Cc: <[email protected]> Sent: Wednesday, May 18, 2011 1:22 PM Subject: Re: [FlexEdge] More on 6M hum Ted: There is a 300 Hz High pass filter in the audio path. Tones below 150 Hz should be attenuated by over 40 dB. Where are you getting the audio from? Are you using the audio output jack on the radio? --- Graham == On Wed, May 18, 2011 at 1:32 PM, Ted Leonard <[email protected]> wrote: Hi Graham, Thank you for the speedy reply. My Neighbor and I have tried all sorts of AGC settings to no avail as far as the hum is concerned. If we turn off the tone the hum goes away and audio is fine. My repeater sends out 127.3 at about 350 Hz level for PL most receivers of course strip it off so you don't hear it. If we go to simplex on 6 FM and use the tone the hum is there, turn off the tone and hum is gone. Playing with AGC settings has not even reduced the hum as long as a tone is present. My humble thought is the low end needs to be filtered out then all will be well.
