Hi Bret,
When using the DXplorer.net simultaneous receive measurement system, its best if you have the capability to start your testing by simultaneously transmitting through a Magic-T combiner into a single antenna. In less than 30 minutes you'll have enough data from DXplorer.net to calibrate out any power output difference between the two transmitters. After you've completed the calibration you're ready to connect each WSPR transmitter to the antennas under test. 73 Frank W3LPL ----- Original Message ----- From: "MaverickNH" <[email protected]> To: [email protected] Sent: Tuesday, May 16, 2017 6:37:31 PM Subject: [Elecraft] [K3S] mW TX for WSPR I'm trying to fiddle the TX power on my K3S using WSJT-X WSPR 1.7 on a 43ft Vertical to match the 200 mW output of a WSPRlite over a random wire dipole antenna, using the DXplorer.net simultaneous RX measurement system https://tinyurl.com/mthms72 . Is TX wattage continuous with rotation of the PWR knob? It has 0.1W decrements and I seem to find equal performance between 0.6 and 0.7W on the K3S and was curious if halfway between 0.6 and 0.7W as I rotate the knob is 0.65W? I can imagine precision of TX power isn't accurate to more than +/1 0.1W but thought I'd inquire.
