A friend of mine, Ted G4NUA, is busy building one of the Walford kits called the Fivehead. He is doing the 20m SSB version which puts out around 1.5W pep when completed. So far he has got the RX part working (see picture of the build so far), which shares a lot of the IF with the TX part. The PCB is not silk screened making construction a bit more tricky than for an Elecraft kit. This is presumably to reduce the kit cost. When finished it should make a credible QRP rig for 20m, although 1.5W on SSB is a bit lower than I'd like. There is an option for a 10W PA add-on if Ted struggles to get contacts.

Walford Kits "Fivehead" SSB transceiver
A friend of mine is building a Walford Kit "Fivehead" SSB transceiver. He has got the kit, but was surprised to find the parts placement was not silk screened on the PCB; I guess this is a cost saving measure.
Although there is a not-to-scale layout, a clear colour photo from above of the assembled board from the component side would help him a lot. He's asking Tim if he has one he could email, but does anyone already have one they could email me please?
