Hi Larry, I've seen this too. I'd always assumed it was something in my external auto-antenna tuner that was making a poor contact and that, because I was passing current through the connection when I transmitted, that made it became better. It's possible too, though, that it might be something in the SDR radio, such as a relay making a poor contact. (In my case, I don't believe it's a software glitch.)
Next time it happens I'll try to remember to turn on another receiver and check if it's also attenuated through my tuner. If not, then that would point to the SDR (or my antenna switch), rather than the tuner. - Jeff, K6JCA -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Larry Loen Sent: Sunday, March 04, 2007 3:21 AM To: FlexRadio reflector Subject: Re: [Flexradio] Receive Attenuation Glitch With at least the 1.8.0 level, there's a little glitch I've noticed that might also be related to another recent thread. Sometimes, when I've just turned the rig on, I find the receive is attenuated an extra 20 dB or so somehow. It actually looks, visually, like a good deal, because the noise floor is down 20db. To clear it, all I have to do is transmit, however briefly. The noise floor comes right back up to normal after that.
