Hi Jack,
Yes there are/were EEPROM emulation libraries for that SAMD device.? However, they use common program space.? So on reflash of firmware, the values would be erased.
We've had conversations about smartly avoiding misuse of FLASH as EEPROM in the past.

Re: Alternatives to Baofeng mic?
Some mics will have more gain than others. You readjust the gain back from the RV1 in the predriver. Between 8 watta and 10 watts the difference is entirely imperceptible. - f

Hi Ted,
I'm having trouble finding the sketch for the second Nano. Can you point me to the code?

I agree 100% with Evan. If it ain't fun then it's like a job! Can I suggest you get a uBITX with just a 2 line LCD display (not sure what you have now). There are minimal menus to work with and thus less frustration. From what you describe, your project is overwhelming you beyond what you expected. This kit was never intended to be a plug n play radio. Perhaps solicit the help of another Ham and work on it as a team project. We have done that locally with great success here in VE land.
What ever you decide, best of luck and best wishes for 2020 - keep the faith - help is only a few questions away!

Re: [SoftwareControlledHamRadio] radio shack 62/36/2 .022" back in stock online
Thanks, Doug. I just ordered 3 rolls (free shipping!) as this is the best solder I've ever used.

While this is not software related, I seem to remember a discussion about solder with the radio shack 62/36/2 coming up as the favorite of some.? I forgot I had set up a restock notification and just got the email that it is back in stock online.? I do not know if this is actually the same as the old stuff.? For those of us in the US, $7.50 for 1.5oz is not too bad.? Free shipping at $19 otherwise about $3.? This is better than the pocket paks of Kester 83-7145-0415 I've been buying.

Re: S-Meter on Nextion Display
Thank you Ted, this is great info for me, I will research! I have sat
on the sidelines since v1, watching the uBitx develop; I am a big fan
of AFarhan, I think he is a kind of hero...and the v5 with Nextion and
CEC firmware is the way to go for me! HAPPY NEW YEAR -- Rich WB2GXM

The S-meter in the CEC NX_S software will work fine though some have added a
simple audio amp (LM386, etc) between a tap from the yellow (vol pot "high")
wire on the audio header to Pin 7 of the Raduino header in order to get full
range from the meter.? One then uses part of the Memory Manager software (
) to
set the lower and upper range of the meter readings.
If you do take the time to staple in a second Nano processor into your build
and blow additional firmware into this second Nano, then add a few wires, a
small disc capacitor, and a pair of resistors, your S-meter will react a bit
faster AND you will get some extra features that are neat to play with (and
you don't need an additional audio amp to feed it).? Here's how:
This is amazingly easy to do, if you don't mind soldering wires to the Nano
pin positions. It certainly takes no more work or time than it does to wire
in a second audio amp for feeding the meter direct.

Re: Alternatives to Baofeng mic?

Bitx40 ~ New life running FT-8 and WSPR
The uBitx V6 undoubtedly is the radio? du jour and rightly so and .after all it is the bright newest shiny toy. High marks for this latest iteration! But if you have a Bitx40 lurking in the closet, I have three hacks to accomplish the following
- Provide an Alternate Controller for the Raduino
- Modify the Bitx40 so that USB and LSB are achieved using CLK2 on the Si5351. The on board BFO crystal is disabled
- Modifying the Bitx40 so that USB and LSB are achieved by shifting the LO from 5 MHz to 19 MHz with a flick of a switch. The on board BFO crystal is used for both LSB and USB
On the air tests with WSPR and FT-8 have shown both of these approaches as a viable means to get USB with a Bitx40. Future development will look to using a tunable Transverter with the Bitx40 so it can be translated to 6 Meters.? Documentation on what I have done can be found at Happy New Year! 73's Pete N6QW

Re: Alternatives to Baofeng mic?
There is a lot of myth around these mics. I have seen some hams spend a fortune on their microphones. Most of this is quite useless. Let me explain, why. 1. The audio channel of an analog radio is limited to frequencies between 300 hz and 3000 hz. The frequency response of your mic below or above this not of much use. On the other hand a podcast recorded in FLAC format, sampled at 24 bit and 96 khz will sound very different between electret mic of the ubitx and a blue condensor mic. 2. Flatness of the mic's frequency response. This too isn't of much use. The crystal filters variations will dominate any gains you have at flatenning the response. In any case, less than a db of variations are hardly going to register at the other end. 3. Distortion. Most of the times, you want your voice to be compressed and hence distorted. We use ALC to up the gain while talking softly and then push the gain down while yelling. Additionally we use clipping and compression and this leads to distorted audio.? Save yourself the money, buy yourself something nice and better instead.
