Just received this little guy today. Hooked up a simple 20 Meter Vertical with 2 radials. Tuned it to a 1.3 SWR at 14.074 MHz. I plugged in a Type C USB, a 12v battery, and fired up WSJT-x on FT-8 Mode. Inside WSJT-x, I set the Radio type (Kenwood TS-2000) and connected to the PnP Input & Output streams. OMG! The signals started arriving one after another. I started picking CQ stations and replies came in just as quickly. Connected with 8 stations in a matter of minutes. Now, to re-read the manual, check whether CAT will adjust a split frequency, and explore what QRP can do. I am very pleased with this tiny but powerful little radio. In the USA, expect a few weeks delivery and a registered package from the USPS. In my case, Malta PO did not supply tracking so it was blind for most of the delivery time. Patience and you will re rewarded. The device came exactly as advertised. It was set for 20M with a 20M module installed. You have to track down the DOC's via Github but it just takes a short while to gather everything you need. Read the paperwork manual that arrives carefully and remember to check settings BEFORE applying power.
Delivery was really quick - added bonus was that Malta Post communicates with Royal Mail and delivery updates come from Royal Mail.
Love the radio. Great packaging and worked straight out the box. Issues I did have were my problem - used a noisy switched mode power supply initially and interference from a nearby power line adaptor.
I printed the case, but will have to re-print with modifications as the rear panel holes do not line up properly with my revision of PCB. Used the 5cm ‘Visaton’ speakers from CPC.
Would buy from Jason’s Kits again.
