manual for Reeds firmware for v6
Hello,
I am about to update my new 6.2 with Reed's firmware and was wondering if there is a guide or manual on the features and how to get into the setup etc.
Thanks,
Gary

Thanks to all that replied. All is good now.

Thanks Gary. It was helpful to have something to follow.? I was changing to Axicom relays and have put the affected section on a daughter board.
Thanks again Stay safe Ken

Re: Revisiting lower power output on 40m, V6

Yes, all of these were done on the common cw/SOTA frequencies.

I did the capacitor substitution also but 40m remains stubbornly low.
Here is my current reading with a .056 capacitor at C81: CW Mode
80m 10.2
40m? 3.2
30m? 6.0
20m? 5.2
17m? 4.0
15m? 6.0
10m? 3.5
This is a general improvement on every band except 40M which got to 4.0W with a .01 cap; other bands were no so great.
I think I'll live with this for now and keep following the thread.
Cheers,

If you're using the stock software, power on the radio, then press and hold the knob button in for a very long time. It takes 10 seconds or so (feels like forever)

Hi all, I'm VE2OL and just got? ubitx V6 and I can't get into the set-up menu to change CW type key, it came with keyer set-up and I want to switch to straight key function.Any tips will be appreciated, thanks and 73, Ray

Exactly what I found on some boards. One had a mixer diode leg open and was partly deaf.

Good effort. Await to see the performance as you assemble, Gerad.
Congrats

Re: Adding a SI5351 on uBITX for 116MHZ
You could always have a second arduino nano or pro mini with the si5351 module for the transverter.

Re: ubitx 6.2 bench calibration frequencies?
Note there is no exact number that applies to all as the crystal filter?
uses real crystals and they vary from lot to lot.
What that mes is for the BFO one guy has it right a 11.05552mhz and
the next one might be more like 11.05529.? Ih this case 100hz is
significant!.

Re: ubitx 6.2 bench calibration frequencies?
the earlier V3 and maybe 4 used 12.000 mhz crystals in the filter for a 11.995ish?
BFO.? The latter version used 11.059mhz so the BFO (clk-0) would be about 3-4khz
lower than that maybe around 11.055ish.?
CLK 1 should be in the range of 11.055mhz + or - 44.985mhz.
I'd go into the cose and insure the starting base frequency before alignment
is close to those.? ITs possible to get that way off if the code is for the older
V3/4 ubitx.

Finally found the culprit, R18 was cooked no doubt due to my frolicking with the pan adaptor, apparently pressing on the board made it work again... sort of... this could be observed with voltmeter, infinite resistence then when pressing on board it went down to about 60 ohms. I tacked on a through hole 10ohm resistor (correct value) and all is working well again. Can't complain this is exactly the sort of shenanigans I bought this thing for!

It is rather easy to damage capacitors by subjecting them to excessive heat when re-soldering them.? I would start by bridging suspect capacitors in the touch-sensitive area with a good unit of similar value.? It may be as simple as an intermittent capacitor. _._
.. so further troubleshooting on my ubitx revealed R16 was actually ok. I seem to have a problem with maybe a bad connection in a trace, when I press down in this specific area the receiver springs back to life, whenever I release the pressure it goes quiet again. The only thing I can think of is a damaged trace but there are no obvious signs of damage.
any advice on how to troubleshoot this before I start running patch wires ?
Thanks!
