Hey, all. I have two 6-pin (RJ14) ports on the front of my portable setup, one for a microphone and one for JS8, etc. It's really simple and requires no extra parts. The data transmit audio (and the r

I'd go to kitsandparts.com and order a T200-2 torroid, then, pass your lead-in coax through it as many times as it will fit (but a minimium of 4, maybe 5, passes). This will serve to clamp down on str

These points have 12V on them when in transmit mode, according to the schematic for a V4 (and should be the same for later designs): R89, side opposite of C86 U2 Pin 3 (near the 3-pin power connector.

Oh, and for a dummy load in a pinch [at these power levels], get an 1157 tail light bulb and solder both filaments (pin) & shell (earth) to a male BNC or whatever you're using. I wouldn't keep it key-

K5FJR de K3RTA, This static of which you speak, is it there mainly when you're transmitting, or at any time? I ask, because it smacks of RF infiltration (or "leakage). Your other rigs may not have thi

Anytime I try to put a condenser element into any other microphone, I'll find some soft foam padding in a sheet or in a block that I can cut into a neat piece to fill the inside the subject microphone

Roger on the flywheel niceness. One might take note that some of the industrial, optical rotational encoders have roller bearings on them; others are brass sleeve but loosen up nicely after being kept

Dave, The P/O probably wired the jack that way rather than as a paddle jack examine the available schematic for working with paddles, and modify the jack accordingly. Have fun, Ted K3RTA

Bob, What is OTG function and how does one hook up pRxTx to the uBitx? Ted K3RTA

Adrian, I came across 3 or 4 optical encoders on my day job that convert nicely to work with a uBitx..... in theory. That is, I've tested one of them but have gone no further as yet. In their original

Hey, Bob, I'll have to double-check on the BFR106 and make sure I put it in the radio i think it went to. Sorry the 2N5109's didn't pan out; I guess that was a deal. Here are some 2N2222's I've used w

.....but if you really want 2N2222's, these seemed OK when I bought some a while back - https://www.ebay.com/itm/401310061467 -ted

Rather than swap the 6 predriver and drivers with them, go for three of these & a spare - https://www.ebay.com/itm/401310061467. Better output, especially upstairs on 20 meters and up. You only need o

Hi, Bob (again). I was at physical therapy while composing the other note and my turn for abuse was coming up.... Continuing on your questions, my guess is that after you tie the tops of those resisto

Rob, I didn't consider simply running the two resistors on the board in parallel, I went and soldered a new one on top of the existing one, etc. But why not do it your way, indeed. Regarding transisto

Different value and I've forgotten where I learned to order 720mh inductors, but, I've got a few extras of these: https://www.ebay.com/itm/JW-MILLER-PM7232S-R72M-Fixed-Inductor-720nH-12-5A-8Mohm-SMD-N

Bonjour, The proper setting of the BFO is very important for output power as well as for receiving, it seems. I would suggest setting this to 11,056400 and see how the output power is on the bands. I

Thomas, et al, "Spectroid" by Carl Reinke, or any audio spectrum display available for a smart-phone or tablet, works. While I applaud HF Signals for making a utility available for the purpose, it's c

Well, there is this........ an end-fed multibrand using a trap. http://www.infotechcomms.net/downloads/Multi_band_EFHW.pdf

Hold the presses!!! It seems I forgot that the CW pull-up and paddle resistors are part of the V6 board, now, so there's no need (and possibly a problem) in adding anything other than a key, to the CW
