Has anyone tried the short version yet? I prefer to have power source outside the transceiver box. If not, I will be attempting the short version when my printer arrives. Probably a Christmas break

Yes, Jan ... it was the same tracking VK3YT Picospace balloons across the Pacific over the last 2-3 years. Several stations receiving out to 2000km, then a few to 3000km, then just me for

HI Barry, That is very low indeed. Please double check the solder joins in the LPF, especially on the toroids, make sure the enamel coating is removed. Also check for continuity between the PA mosfet

Bob I note that you are the only one receiving BB01. I know that you have extremly sensitive ears. But is this what you would expect ? 72 Jan

Nice Job

Hi, This is a tight fit but it does go in. Martin G0PJO

Hi Ken. Ok thanks, understood. Now to go and get the receiver board etc...If shipping times have improved, that might be my Xmas project 73 Roger --- ** Roger Hill **

Hi Wes, I used 0.14mm2 which is roughly equal to AWG26. For the supply you might want to use slightly thicker wire, AWG24 will do as it is rated to 2.1 A @ 75degC (typical current draw is 500-600mA

Sorry, did not answer your specific questions... ''Now comes the bit I am unsure of, and that is the Park setting. The receiver notes say use park mode 4 - but that is only one frequency. But the U3S

Hi Roger, Yes , I could see that working. A bit of extra loss in Rx mode though. 73 Ken G4APB

Thanks Ken. Since the 'LPF always in series' is the highest frequency, I figured it would not matter if I had it in series with the BPF's..they would all be for bands lower than or equal to the

Hi Roger, It certainly is addictive, especially if you try to build ‘outside the box’ ideas. I have built a multi band hopping rx and a multi band tx/single band rx transceiver, but your ideas

What gauge wire should I use for off-board mounting all the controls? I’d like to buy three conductor, braided wire? thanks in advance.? -- 72/73 Wes WM7WM

After winding T1 for my 40M QCX, I decided to have a little fun before mounting it, and perhaps get it right before mouinting it. I installed some header pins at unused location C8 (in the 40 meter

Hi all: WSPR is addictive! This is my first post to this group, so please be gentle. I have a U3S, running on 3 bands at present, 20, 30, and 40. I am using the relay board to hold two of the

Steve, the transistor arrived last week, and I had some other things that sucked away my time. I just did replace the transistor a few minutes ago and It's now a solid 3 watts to an antenna. Of course

30 Metre QCX on a 12V battery.? Firmware 1.00d Looks like I'm only getting .21 watts out.? WSPR works well at that power but no CW contacts yet.? I'll have to do some more research to try to

To followup, I found the issue with the progrock blinking three times rather than four: a sagging 9V battery I was using for testing. I plugged it into 13.5V from my Astron and it operates as it

Hi Bob, For my qcx20meter I measure with a precision lcr meter every toroids. The L4 for 20 meters on red amidon 10 turn is over the 0.40microH. I found 9 turns is pefect. After initial calibration I

Wow. ?Many thanks. ?I actually have one of QRP Labs dummy loads with that convenient test point for RF. Thanks Nick. I’ll have a look when I’m in the shack. -26c in Sudbury ON this am. brr
