I believe that you are looking for an old-school MARR connector, as opposed to a common MARETTE or WireNut. The MARR uses a brass insert with a set screw, whereas the latter is basically a spring. A

If possible can you screenshot your config window for the radio. I will compare it to mine in the morning. I am using Ubuntu 18.10 with wsjtx 2.0 and it runs just fine for me one I got the setting

I know this is an old thread but I just started playing with WSJT-X 2.0 FT-8 on my uBitX. I'm running it on Ubuntu 18.04.1 LTS. It runs OK, at least in receive mode...I haven't tried transmitting yet,

Dave, About all I can say about your link is the part number looks correct and it is relatively expensive.? Not much supporting info though... I ordered mine directly from MiniCircuits.? The MAR-3+

Bob Please scroll down less than a week ago, someone posted some very nice photos of front and back side. Hint, sort by topic and you should see it. Curt

Can someone post a pic of that type of wire nut with screws.? Thanks Guy WB7SZI

Thanks Woody I'm looking at parts. Is that MAR3 chip?

Thanks Ted.? Interesting didn't think about using a board like that, it is an interesting project to try. For just audio gain I was thinking about one of

Dave, FWIW - My mod of bypassing the audio output section entirely and using a 741 opamp followed by a audio power amp IC gave strong audio...? It was still somewhat RF deaf but the mmic amp /

We've discussed the disadvantages of making all of the files ino files before. The biggest loss is you give up incremental compiles. For me, compiling 210K of program code dozens of times each day,

First, K3 is the main TX/RX relay so it's not trading an entire circuit in or out of the mix; it's just routing one point (antenna) to one place (RX) or 'tother (TX). The quick way to see a difference

Michael makes a good point - that even an inexpensive product needs to meet the minimum regulatory requirements to be considered serious beyond people (like myself, admittedly) who bought it knowing

I wonder if there is a bug in the software to make the transmit signal wrong.? I will debug it when I get a chance.? Either way though I should be able to compensate for transmit frequency being off

I tried to model the agc on multsim but not sure I did it right the signal doesn't appear to come out correctly https://www.multisim.com/content/JhzoMNRpMHvSBitkNMNuZC/agc-ubitx/

I believe that there is uniform agreement that the relay replacements do reduce the harmonics.? That is the issue that is solved by external low pass filters. The spurs issues for 20m and higher

I cannot find out if ubitx.net is part of the designers support but they seem to have up to date mods at this location: ubitx.net/%C2%B5bitx-strengths-and-weaknesses/. The authors claim these mods

Hi Gary... well you hit the nail on the head. I put all the ino's one after the other and it compiled ok. However, the Bitx goes into cw mode and sends code? I dropped each ino in the editor one after

Trying to debug a faulty ubitx v4 with old eyes so an electronic copy of the component placement or board silkscreen would really help. 73 Bob GM4CID

Saved that site. But on that page they only have Push-On Knobs - "D" Shaft which means 1/4-in "bore" or hole and I did not see one for a smaller shaft. May on another page. Thanks for the website. May

When I'm building and need an item that is not handy, the first thing I do is look around to see what I already have to use in the old experimenter's tradition. I thought about the shrink tubing idea
