Micro Build Report: QRPMe Sudden Storm

Sometime in 2023 I’ve purchased a couple of ham radio related building kits (Tuna Tunah, Two Tinned Tunas, Tuna Helper, Tuna Topper) from QRPme, a ham radio kit web shop run by OM Rex Harper, W1REX. One of those building kits is called Sudden Storm. The Sudden Storm kit is a rock-bound CW receiver for the 40 m band. Rock-bound means that there is no VFO (variable frequency oscillator), so you are stuck with the frequency of the crystal that’s mounted into the receiver circuit. The kit comes with two crystals: 7,030 MHz and 7,122 MHz. However, with a suitable upgrade kit you can also operate on 80 m, 30 m and 20 m. It’s a well made little kit that can be easily assembled although – in difference to other kits made by OM Rex – one does have to consult the detailed assembly instruction manual. Below you can find a couple of images from the build process:
