Title: Fall Classic Exchange with my SCR-274N Post by: k3msb on October 09, 2018, 11:35:10 AM Did anyone else play in last month’s Classic Exchange (CX) with their Mil Gear ? AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
I drove my SCR-274N for about 24 CW contacts on 40 and 80. The receivers used an outboard power supply (I have a hum issue that I need to look at when using dynamotors) but the transmitters were powered by the dynamotor on the BC-456. The power source were two tractor batteries in series across the float charge output of a 28V power supply. Power out was just under 20W CW; a bit low but I was only getting about 23.5V key down off the batteries. With only 8W output on AM I didn’t even try..... :-\ |
