Re: receive works great, but no trans power,
#ubitx-help
I certainly wouldn't dump it. Could sell it on the forum here. Could state your location in the forum, see if others live close. Could haul it into a local ham club meeting, see if anybody is?

Re: Ubitx version 4.3
Enormous bandwidth? Are you using this rig mostly for CW? It is primarily designed for SSB use, CW is an afterthought. The crystal filter is around 2khz wide, as required for SSB use. The easiest

Ubitx version 4.3
Hi all. Just received and built the latest ubitx, and have encountered a couple of seeming problems. It is all wired up according to specification. First problem is that there is little or no audio on

Re: receive works great, but no trans power,

Clark & Jerry -- thank you for the guidance!? I think I'm getting in over my head here. I'll try some more basic debugging, but if I can't figure it out, I may have to put it in the dump and call it

Re: Q70 replacement
Used to use a lot of them in repairing audio gear in the 80's and 90's. We got them from MCM Electronics then. Probably discontinued now, so probably have to get them off Amazon or eBay. Google shows

Re: Q70 replacement
I would look at old 10 & 11M equipment. The NTE equivalent is a NTE 85. Good luck, Marco - KG5PRT

Thanks Michel, I don't have my smeter together yet but I think I can fix this problem pretty easy. It should go all the way out to the +20, did you calibrate your s meter using Ian's procedure?? I

Re: Q70 replacement
With RX voltage of 13.6, the Q70 collector voltage is 4.67 on the 2sc945. I should mention that I added a 16K resistor from the base to ground when Q70 was a 2n3904, which was suggested by W3JDR to

Re: receive works great, but no trans power,

Yes, an RF probe is a good idea to have around when debugging a uBitx. That looks like a reasonable circuit, but good luck finding a GEX66. Seems to be a germanium point contact diode from 50 years

Re: Raduino fix leads to no receive uBitx

Hi Gordon, I measured mine without any load and I had way too low output level on CLK2 and CLK1. It was a bit dependent from the frequency I tune in. Then I modified the code in the ubitx_si5351.ino

Re: New file uploaded to [email protected]
Hello Allen. Very good the file for the Nextion 35 B. I noticed a small problem: The S / Meter never exceeds the S9 even on a very QRO signal. It looks like it's stuck at S9. Thank you for the work.

Build yourself an RF Probe such as at: http://www.qsl.net/g3pto/probe.html <http://www.qsl.net/g3pto/probe.html>. You can use it to trace the signal (or lack thereof) through the transmit path. Clark
