PNP CW QRP Rig now on 40M

 





The home-grown rig has been moved to 40M on 7013 kHz and gets 12 Volts PTP out of the W3NQN LPF. That is 360 milliwatts. At 7 AM my signal was heard in the 600-to-800-mile range. 


I have ordered "rocks" for 7030 and 7055 kHz. (The original MC1496 DCR was built for 40M.) The additional power output can be traced to the crystal itself and that the circuit components in the driver stage favor 40M versus 20M. The emitter bypass cap in the driver plays a big part in the frequency spread.


Them that know, survive. Of note do you believe only a couple of more weeks in the Iran war. Reminds me of when I went to Vietnam... like 10 years. Survival depends on trusting your gut and the actions you personally take.
