The Heathkit Lunchbox on 75m AM

K6KWQ has just built a Small Wonders Lab "Retro-75" QRP AM transceiver kit into an old Heathkit HW30 (Lunchbox) case. The Retro-75 puts out 2.5W AM on 80/75m and is a nice way of getting back on AM on the band. AM is quite popular in the UK with stations active around 3615kHz.  Dick has made a very neat job of re-labelling the old Heathkit box so it looks like a genuine Heathkit rig, but for 75m AM.

20m AM

IK6BGJ was a good signal this afternoon on 20m AM on 14.251MHz. Although he called CQ AM many times he did not work anyone and was unable to hear my QRP reply when running 4W AM. Pity - it is a very long time since I've worked anyone on AM on 20m. 1967 to be precise!
