Re: Top band transmitter
Re my comments in post #22, some clarifications. The design I was thinking of appeared in PW in Jan ’67, called the “Ten-Five” transmitter by A.S. Carpenter and used 6BW6’s for both the PA and the single-ended mod. The construction was notable in that it’s base measured only 8 x 4.5 inches.
In Sep ’68, Carpenter published a “QRP Modulator” design using an ELL80. Another option for the modulator would be the Pye Ranger design using a pair of EL90’s and the “bean can” transformer.
Can anyone tell me about AM activity on 160; are there any particular frequencies worth checking or anything like a calling channel?
