John let's not conclude anything yet - but suffice it to say WSPR can be rough on this rig - the original QCX without any heat sinking on the bs170 finals. I can't speak to the qcx+ on WSPR, but the h

Most of the "12V" power supplies sold to hams are really 13.8V supplies out of the box. (Many of them can be adjusted with an internal trimmer.) A lot of ham gear is designed to operate best at that v

Steven because they are not required, just the .hex 73 Alan G4ZFQ

The .eep file is not required. On 3.12a. Once press any key is executed, it sets up the required variables. Your input in the menus then is rewritten over these Initial settings. Hope this helps..
