If you actually duplicate the AGC circuitry in the K2 for the S-meter would probably be a simple move. S-meter readings are okay but I don't trust reports from others because very few people have calibrated S-meters and even if they are they become dependant on RF Gain Settings, Preamps and attenuators. They are what they are a Relative Indicator and nothing more when it comes to most Amateur Radio operation. I usually leave the RF gain at full unless I'm on the TopBand and just use Xtal filters and the DSP module to give me a clean received signal.
Anyhow on most Contests and other things you always get a 599 as everyone is too intent on making contacts to actually give you a real report. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darrell Bellerive Sent: Sunday, March 11, 2007 12:23 PM To: elecraft@mailman.qth.net Subject: [Elecraft] AGC Independent S-Meter? As I typically leave the AF gain at maximum and use the RF gain control to set the listening level (Better signal to noise ratio.) the S-meter is not too useful. Also with the AGC turned off the S-meter is not operational. Anyone have any ideas for an AGC independent S-meter? I was thinking perhaps use some sort of high impedance RF voltage detector between D34 and T7 on the RF board. Then amplify the voltage to the level and range required at the S-meter voltage connection (pin RA1 of the MCU), so the existing meter could still be used. Of course the connection from the MCU to the AGC line would have to be disconnected. -- Darrell Bellerive Amateur Radio Stations VA7TO and VE7CLA Grand Forks, British Columbia, Canada _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
