Mike, I agree with everybody else that your getting RF back down the feed line, it happens bad on my Par EFHW on 20 meters. Thanks for unwittingly giving me a tip on where to buy my case for my uBitx,

I added a file/photo showing the reversed side mounting pins for nano

Forgot one... Painted box, did you clear the pat at the coax connector and use the star washer? Same for the board mounting standoffs, All of them. Allison

Mike KK7ER, What form of end fed 1:9 with random wire very bad without counterpoise. Or resonant half wave (swr under 1.7:1). FYI if not low at the desired frequency read the manual and tune

Add in 6b : modify the raduino vanilla software to use kd8cec memory manager and get the settings -so you can put these settings in your other nano with the kd8cec software neesing very few

You said you are using the coax shield as the counterpoise? RF pickup on all bands or all bands? Try changing the length of the LW + or - and use a 1/4λ counterpoise connected to the case.

Warren, I it was soemthing easy to try but I'd call it the same as you. Lots of harmonics in square waves and little filtering. At frequencies below 20MHz the filters at the amp output are the

The signal at TP1, the output of the first mixer is a pure square wave as it is derived directly from the Si5351 in CW mode. The signal in SSB mode is much closer to a sine wave as it is a mix of the

Hi everyone, can anyone please supply the wiring diagrams or photos of the correct connections for thee small pcbs that came with my kit cant find any wiring details anywhere any help would be most

From what I've been able to find, if it has silkscreened component locations, it's not a PWB, it's a PCB. Most people use PCB nowadays. http://www.circuitnet.com/experts/59367.html

Thank you Warren. Your VNA and 'scope plots illustrate very clearly why in antenna literature, "all band" doesn't mean what most folks would have it mean - it almost always means "lossy". Even

Wow. I missed that completely by using the front panel PCB that came with the enclosure from amateurradiokits.in. Seems like with online resources like that, the schematic and wire-up page could get

I found out that the MH3 mike that came with my KX2 works peachy plugged into the 3.5mm PTT/MIC jack. No wiring, no fuss. The up/down buttons, of course, don't work (they cause PTT), but otherwise,

Thanks, Don! In a surprise move, the problem turned out to be uncarefulness on my part. My confidence was misplaced, since I'd used wrong capacitors in a total of four places: both caps in the circuit

If you can, put in 8.8.8.8 for your first name server and see if that does it. That's google's name server. Vince - K8ZW. -- Michigan VHF Corp. http://www.nobucks.net/ http://www.CDupe.com/

I went a slightly different direction and picked up a cheap temp fan relay from Amazon: https://www.amazon.com/gp/product/B00GWFK7FA I superglued the probe to one of the finals heatsink and then

When the rig is not powered or in the receive mode there should be continuity from the Rx connection point to 12V. through relay K1 contacts 3 and 5. That is normal. The squeal is not! First step in

Hi there.. do step 3 before step 2. Install that resistor first. Then apply power. 4. The software is already 'loaded'. After you install in a case you will have left me behind. I am not interested

Allison I will try lowering the drive to see if it corrects the problem but I am skeptical. I first noted the problem when probing TP1 with the PA unpowered. The discrepancy is already visible at that

I just received my ubitx building this weekend on cardboard to see if works. Questions on steps 1. build on cardboard 2. power 3 place 4.7k in key jack 4 ? do you need to load software? 5. Final
