[MRCA] Sunday Night OMRN CW net

[Ray Fantini]

The BC-474/ SCR-288 was never up to US Mill Spec especially when compared to radios like the BC-654/ SCR-284 and  I think the radio was originally designed for a forging government and in the US government bought it being they were buying anything that was available at the time but that’s just speculation by me.  I would assume that it was never intended for use as anything beyond a training set, but that being said don’t get me wrong in that looking at the design have to propose that unlike much of the exceedingly heavy designs that occurred in Mill spec radios of the time the little 474 with its AVR receiver and simple plate modulated transmitter is just about what I would say is a perfect example of what you would get if it were designed by and manufactured by Hams?

Excellent condx tonight on 3570 with Ted W3PWW  NCS. Nice collection of chirps and clicks and some drifting in frequency.   I enjoyed the "shave and a haircut" just prior to the net.  My rig for the evening was a BC-474 (on the bench) powered by  home brew 12 volt switching supply and running 4 watts. Working on details on a web page. Learned something tonight that I had forgotten, when using a older receiver that is not "single signal" when you hear QRM it is possible to tune to the other side of center frequency to reduce the interference.  Everyone should tune in on Sunday night at 21:00 hours local time just to hear the different signals.
