I have now completed the build of my Miss Mosquita 3 a 40m CW transceiver.
I decided to mount all controls and connectors on the front as I feel this is a better configuration for a portable rig. The antenna connector was swapped to the RCA to save some internal space, and is reasonably common amongst qrp gear, so not too out of place.
The push button ‘f’ is for the freq-mite which announces the operating frequincy in morse code
Upper left is the Freq-Mite pcb, just below it is the Simple Keyer from QRP Kits with its Peizo mounted on the perf-board.
TX power, at 10.0v- 2.4W, 12.0v- 3.4W and 13.8v- 4.4W
Drift is around 180Hz in the first minute and a further 300 Hz by the 5min mark, it then settles down and is not noticable on all but the longer qso’s.
Tuning range, 6997 to 7046 KHz (49KHz) and quite linear over the full range.
