Hello Ken, I too am a little confused with the difference between Rx mode and the use of Park Mode set to 4x Rx freq. For a few months I have been running a U3S on 30m with a QRPlabs

Hans Can you answer this please, I’ve not had any takers from the forum:- I am trying to build a 7MHz transceiver using the U3S Tx as the LO. What is the difference between using the ‘RX’ mode

Pat, I have a number of different cells here, the normal 18650 and the 'pouch' style. for preference I have used the pouch style as it is very high energy density per volume, but more prone to

Mike, would you mind posting more about your results with the XL6009, and maybe a wiring diagram? It sounds like a great way to vary the voltage in to get the RF output right - if it's not too noisy.

Running a 3S LiPo/LiIo in a pack you need a BMS to balance and protect the cells from over/undervoltage. These are widely available on ebay, search for "18650 3s bms" or similar. For charging you need

That's a good idea. I have a power pack of three 18650s that I built into an Altoids tin to power my HB-1A, but I have to remove the cells and put them in a separate charger to charge them up. I'd

Hans, When you get back from your break (please - not before!), would it be possible to clarify the kit serial number from which the new firmware version is used? You have done a fantastic job! Thank

Mine would have been first if I had remembered to send it from the account that I'm subscribed from ! D'OH I only used the ztx550 because I have some "in stock". There may be better

Hi Peter, all Doesn't mind at all ;-) Though I got my answer in ahead of yours despite being on holiday HI HI. I did not have any trouble myself, through all my development and testing. And I have

Hello Patrick. I've been running my third experimental U3S off one of those USB charger units used for charging a phone. It can run for several days depending on ma capacity. I acquired several

All, I have 20m and 40m versions coming - Order #184 (yes I set my alarm early). I'm planning on building them into a case with an integrated LiPo battery. I've never designed a solution like this,

Hi- I finally got around to put together my ProgRock (with the intent of creating a GPS disciplined source for my HackRF). Rather than the 4 flashes suggested in the plans, mine flashes 6 at turn

I hope Hans doesn't mind but I'll answer this since he is on holiday :-) I have observed similar things on my 17m QCX, but only when running from a PSU. On a 12V SLA the output is 2.5W, but when I

Hi Maik Thanks for the feedback. Do you have an AVR programmer? Or an Arduino which can do the trick of behaving like an AVR programmer? I can send you a new firmware version which fixes all the minor

Hi, last week I received my kit #156 that I pre-ordered at Hamradio fair in June. Band = 20 m. Assembly was very easy with the detailed instruction manual by Hans. My compliments ! The Radio initially

The ProgRock output can be keyed on one of the "bank select" pins if you set the frequency you want in one of the banks and nothing in another (0 Hz causes no output, key up). 73 Hans G0UPL
