Title: QRP Lab's Kits
Post by: Teotwaki on May 10, 2017, 2007 UTC
Some Inexpensive tech for radio hobbyists. The kits require some good assembly skills and knowledge of RF circuits but the prices are cheap enough.

Whether building a CW beacon or a whisper mode transmitter these offer some good avenues for fun


Some samples of the kits. You have to download and print the documents.


The Ultimate3S QRSS/WSPR Transmitter Kit is the new edition of the third version in the "Ultimate" QRSS/WSPR kit trilogy. It can produce QRSS, Hell, WSPR, Opera and PI4 slow-signal modes anywhere from 2200m to 2m and even 222MHz bands. Plug-in LPF filters are available for all 16 HF/MF/LF/VHF bands from 2200m to 222MHz.



This GPS receiver module kit includes an extremely sensitive patch antenna, with factory pre-soldered Mediatek chipset RF module. It has three onboard LEDs for visual status indication, 3.3V regulator and power supply filtering, and 5V logic level conversion. It's easy to build and directly compatible with all QRP Labs kits.

Hans is quite a nice guy. Always willing to help. There was a yahoo group but he migrated it to
Lots of traffic and help there. I really need to finish the kit I started.
