Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6
This'll help with the BFO adjustment, JT:
You might have to work back and forth a couple of times between VFO and BFO.
To check your frequency, dial up one of the WWV time signals.? 5000 KHz and down is better at night.? You should be able to get 10 MHz during the day, and maybe even 15 MHz.? There's an audio tone most minutes.? Load up WSJT-X and use the waterfall to read the frequency.? Using the microphone on a laptop will do the job - no need to connect wires from computer to radio.? The all knowing Wiki has the table of audio freq table:
?Enjoy the tuning!

Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6
I guess my 200Khz off frequency may be a bit misleading, Its on receive, and I compared it to my regular HF station on receive listening to a net that runs here every day. I haven't tried TX yet.
This is where I get lost as suggestions for numbers to use etc..., ?I believe refer to a spreadsheet. I had not heard of this till I posted here. Ive looked in the files and think I have found that spreadsheet.?
Thanks Bob and all for the suggestions as every little bit helps.
I warned everyone that these were Ubitx noob questions....lol

Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6
JT, my first question is: What did you use to know you are 200 Hz off frequency? If it's someone's Flex radio, that radio can help you by moving the frequency a slight amount and rechecking and seeing the new number. From this, you can "guestimate" what number to use and recheck until satisfied it's on frequency.

Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6
JT, to use the mike as a CW key, you have to be in CW mode and maybe select straight key from the CW menu (Press and? hold tune knob for about 15 seconds). Watch for others' comments on this.

Hi Tom,
See my message #80495 and link to Github, .
My project is not entirely the same but there is quite some
similitude.? I used the ?BIT-X V5 and didn't change a thing save
for the baud rate of the CAT and the omission of the LCD.?
It works great (at some 30km distance), now for about one halve
year in the "field".

Re: s-meter function on V6 1.2 CEC firmware and Nextion 2.8 display
There are two ways to handle the hardware needs for an S meter function:
1 - Adding an OpAmp, diode, capacitor, and resistors.
2 - Adding a second Nano
Both are covered on the HamsKey.com and Ubitx.net web sites.

The Axicom V23105-A5403-A201 relays MPJA has on sale for 89 cents have 360 Ohm coils.? They suck 33.3 mA @ 12V.
The relays supplied on my original V3 board have 710 Ohm coils.? They suck about half as much current:? 16.9 mA @ 12V.
I replaced my original V3 relays with Axicom V23105-A5003-A201 relays.? They have 960 Ohm coils and suck only 12.5 mA @ 12V. The 5003s cost a little more but if the reduced current consumption is important to you, they can be found on eBay.

If you are still looking for Axicom relays for a v3 board MPJA has them on sale for 89? US each.? Flat rate US shipping is $6.95.? They still have the $9 desoldering iron I wrote up before that makes the relay swap a breeze.

Re: DC40 receiver build, with nano and Si5351
Adam, this is really cool stuff, dc receivers. I built up something similar using, Rick Campbell, KK7B, R 1 receiver. It blows me away with the 'presence' of the sound of a none distorted audio chain. I use my own vfo with a nano and the adafruit si oscillator board. Nothing compares to a gud dc rx.

Hi Jerry,
Thank you very much for your interest and your time.? My intention was to make a board with multiple options so that everyone can install the variants that they like the most. That is why the modules should be pluggable.
Regarding ADC conversion, the sampling rate of the ADS1115 is not critical for measuring S-meter, SWR or current draw values, and yet the readings are of better quality than the analog ports of the ESP32 or the Arduino.
I chose the ESP32 processor because it started from another project in which I was using it and I have taken advantage of a large part of the software, which is already working with another version of the board; it also has WiFi / BT connection (? /g/BITX20/photosearch?q=esp32? ).?Many of the features are already up and running. I am testing the TPA2016D2 amplifier because it can be controlled by I2C and would allow for squelch implementation and effective scan. Again, thank you for your attention, ¸é²¹³¾¨®²Ô

Re: Dummy Load Resistors & Motor Oil
I am not sure what was the question or related interest on this Dummy load and oil topic, but I am using?at home an MFJ-250. It comes with transformer oil, which can also purchased separately.
The resistor inside it, looks like mounted on some kind of socket, and seems to be able to be removed.
I was in the research to do my own dry dummy load too some time ago, and found high power resistors mounted in aluminum?too. The mount has holes for screws to mount on heat sinks.
Those 3W resistors are ideal for a QRP rig like the uBitx, under $0.10 each:
? ? /g/BITX20/message/83338
If I ever needed a really big dummy load for occasional use,
would try the baking soda in water trick:
? ? /g/BITX20/message/83207
No problem at all if that spills on the carpet.
Won't exceed 100C, though the transmitter finals might
after the water boils away.
