Dennis If you already have a ubitx, its issues can be addressed. Honestly my K2 has more mods than this ubitx needs. The spurs can be fixed. I would rather see an affordable mod kit to service the

Hi, Did you run in upper sideband and the other in lower sideband? I think that would make a difference. The instructions I have specify doing that calibration with the radio in upper sideband. 73,

Does anyone use the "Rig" Split operation in WSJT-X for FT8?? I have the KD8CEC v1.1 firmware.? When I have rig split control enabled the frequency increases by 1kHz every transmit cycle.? For

I have finally got my "Franken" uBitx to the point where it is receiving signals; at least from my HP 8642A signal generator. But, there is something strange going on, and I am wondering if anyone

Dennis Ashhar is not very forthcoming about plans!? It would be nice to see the v4 boards getting the fixes we know about that work ... like substituting relays to reduce harmonics and a fix for the

I do have a device I can use to probe. But max rf voyage is 3v. I would have to use resistors with a little trick Jeffery here in the group taught me. I suppose I can try that route and see what it

Hi all. I was looking for the specs of the L5 and L7 replacement. I cannot find the exact yellow ones on the internet. The NLT on comkey are not there. They have NLV type. Is this a typo?? Please your

I'd appreciate advise on whether the 5303 should work, or whether it was a typo, since it's what I ordered.? The 5303 has a coil power of 200mw, vs. 400mw for the 5403.? See attached data sheet for

Dammit!? that email is gmail.

Hmm, not sure my email was typed properly. nz0tham@... I would entertain offers. 73, Bill NZ0T

I hope your coming wattmeter will come properly set with reliable readings at least for CW keydown or average SSB power. It seems there are many cases they sell stuff non properly set. When I got the

Is that the uBitx v5? -- 72 and God bless KD4EPG

I think you meant Hz not KHz. That's easy to check. Put the radio into transmit but do not feed it any audio at all. Do you still see the signal? If so that's the carrier. If it only appears with a

Sorry, I should have also included the place where the receive path is tapped on the BITX40. It is on a separate page here ( http://www.nd6t.com/bitx/Another%20RF gain control ).

Yes, it works just as well on the BITX40. Instructions can be found on ND6T.com here ( http://www.nd6t.com/uBITX/AGCkit ).

Paranormal signal is about eyeballing 1400khz (I think??) below. Receiving websdr is miles away.? If I reduce drive the ghost appears proportionally reduced. ? ?I was told by a club member that my

This sounds more like opposite side band is not being suppressed properly, but hard to tell without more information. If it's a filter problem the signal will be inverted.

On 80M the relays make a big difference to spurs. The ghost will be around -35db at the worst.. not stronger than that. Reduce the drive and see what happens. Raj

I was having few NLT25T-R68J-PF made by TDK, as I bought from comkey.com , a Bangaluru based seller of India. as Per spec they are 5% tol. and shielded. wrote:
