Thought I would post a quick note showing my new radio for backpacking…the SW-3B
My first impressions are that Rx is much better than the tr(u)sdx, although that’s just a subjective impression, but it is much less fickle when it comes to optimum af gain.
I have been powering via a USB 12V dc dc converter (as in the photo) and have also tried it with a usbc pd to 12v cable ( with a pd chip built into the cable, to negotiate 12V from yhe powerbank)
Both work fine, although the 12V dc dc converter is at the limit of current capability…Of course, you need to select an appropriate powerbank to get 12v with the pd cable.
Output is around 5W using the above (I don’t have a straight key to use for testing the output power, and the radio auto detects I am using paddles)
Have made a few contacts and RBN shows me getting out.
Its a great little setup, especially since I xan use a regular powerbank.
Total cost of the radio came to almost £200 once I had paid VAT on import.
