I was always curios about WARC bands and in particular the 30m band my trusty Kenwood TS-520 lacks. I have it thanks to my FT-817ND but still, in part due to my love of experimentation with radio kits, last spring I ordered a Rockmite 30m kit from Rex W1REX (qrpme.com) and one more 40m version of it. This used to be a very inexpensive kit costing $27 only. These days it’s $45 and comes with a spare pair of crystals. Any mods (AF gain, TX efficiency, etc) are extra. The kit has successfully arrived to Toronto after 5 weeks. During BoM inspection of the 30m kit, I noticed one band capacitor supplied was wrong value and that I got two SA612 mixers and no amplifier IC. Luckily I had enough capacitors of various values ordered from eBay before so finding a replacement was not a problem. The amplifier chip I borrowed from the 40m kit and immediately ordered a pack of 20 on eBay from China for a mere $4 in case I ever need a spare handy… Rex W1REX (from QRPME.com) admitted the kit sorting and handling issues he endured while training a new helper and shortly sent me missing audio amp chip at no charge along with my next order. After finishing sorting components according to the BoM I started building the kit.
