Valve Transmitter by Colin Chidgey G3YHV
I enjoy collecting and restoring vintage communication receivers and have the following in working order. RCA AR88D and AR88LF, National HRO, Marconi B28, Murphy B40 etc etc. Many of these receivers have an historic past, having been used by Bletchley Park during WW2 or on Navy ships. Finding the transmitters used with these sets is difficult, so I set about making something using mainly vintage parts. The Transmitter must be suitable to use on todays busy amateur bands.
- Output power is 25 watts.
- The VFO covers 7.0 to 7.05 MHz.
- It has a green "magic eye" to assist tuning.
- It has an excellent keying waveform, better than some modern radios.
