Dave, you'll have the same trouble using either DeOxit red or Gold on the stainless-steel mini-plug [HOSA]. I tried them all. In order to eliminate the oxidation that occurs over time between the plug and jack you'd be best advised to re-terminate the cables with 3.5mm gold-plated plugs. I have

Is it me or is the input level calibration out by 3 dB in v1.9.0 (795)? Dumping a -70 dBm into the front end of the SDR (HP 8648C derived) equates to -67.0 dBm repeatedly for Pre-amp Gain settings of "low/Med/High". Using a new .mdb for this load and have run the Cal routine after ensuring the r

*Jerry, I would suggest you start at the following values; PowerSDR audio buffers: 512 PowerSDR DSP buffers: 2048 (if your running at 96 khz sampling rate), or 1024 if your sampling at 48 khz. D44 ASIO: 512 buffers or equiv. ( I do not own a Delta-44) You may need to tweak or match the audio buff

Crit, not quite clear as to whether you performed the TX Image Rejection procedure or not. Resetting these values to gain=0 and Phase=0 may not work. First I'd say after making absolutely sure you have a solid connection on your "to line out" cable between the radio and the D44. perform the Tx Im

Chris, see bug# 281 on the tracker. This relates to a similar problem on the COM1 port and using the PTT line on the K1EL keyer. Kirb - VE6IV - Eric, It's a little confusing to me in the schematic. It appears that there is a Dot signal {Tip}, a Dash signal [Ring] and a PTT signal
