David,

Indeed, the same great working chip MAX9814 (and PCB) like in my previous post #38230.  On Ebay $ 2.27  :) :)
Hard to overload TX, because it's limited. You can select (wired) between 40, 50, 60dB gain.

Re: Almost all of the firmware has been modified to fix known bugs and enhance CAT communications.

 

So, is there a .ino file so we can upgrade from the Arduino IDE?

Downside is it will absolutely pick up background noise if you're keyed and not talking :). For now I have it powered by 3 AAA batteries, the plan is to use a 3.3V regulator off the 12V bitx line to power it. 
The Analog Devices module has a noise gate to help with that.  On the other hand, I spent a small fortune on it!

I'll borrow 5V from the Raduino to power it.

It'll be in the case with the rest of the radio.

Just saw this posted to reddit.com/r/amateurradio http://e.pavlin.si/2017/12/30/tiny-isolated-usb-to-xcvr-interface-ptt-audio-cat/

Looks pretty similar to what's being discussed here?

Jack, I've got that exact one sitting on my desk right now. As stated above, it is rather bulky. For now I just have it sitting unmounted inside my bitx40 case so I can access the port without dismounting my Raduino. I think it could be mounted _inside_ a panel to reduce the amount of exterior space required, but it still adds quite a bit of bulk.

Glad it worked out Kevin. I neglected to mention that I also used pots to get the values for the fixed resistors !  By the way I found your website and noticed what you wrote about regen sets and their strengths. I can vouch for that ...I built a 3 tube regen a while ago using a heterodyne setup and the sensitivity and stability rivals that of a superhet.

We tested both wsjtx on Windows and wsjtx on raspberry pie, and it worked perfectly.
With wsjt-x, we can use the latest FT8 in uBITX.

Please email me if you have a test before the release.

Last full test Movie before release for tester
https://www.youtube.com/watch?v=GKS1p41CP_s&t=531s

To upgrade the firmware, click the link below. 
http://www.hamskey.com/2018/01/how-to-upgrade-ubitx-firmware.html

Since I have registered the original firmware on the link above, you can restore it to the original firmware whenever you do not like my new firmware.
Do not worry.

The firmware was based on Fashar's uBITX 0.2.

Modified or added functionality

1.Most of the bugs I found were fixed.
  - CW Tone code configuration Problem,
  - Frequency Control Problem - Go to 4 Ghz when going below 0,
  - Screen Update Problem,
  - Frequency Display Problem - Problems occur below 1Mhz,
   and more...

 2.Enhanced CAT communication.
  Compatible with FT-817 and FT-857.
  I tested HRD, WSJT-X, JT65-HF ...
  However, You may get an error re-organizing to release the program.

3.CAT communication is not broken in CW or TX mode.
 If communication is interrupted by strong radio waves, it will probably be recovered within 10 seconds.
 include auto recovery - I have been programming with the FT-817 about 15 years ago, but I have experienced some broken protocol on TX occasionally. So I put this feature in.

4.New CAT Protocol Implemention
  - Read Write Frequency
  - switch VFOA / VFOB 
  - Read Write CW Speed
  - Read Write CW Delay Time
  - Read Write CW Pitch (with sidetone)
 
  All of these can be controlled by Hamradio deluxe.

4.Save mode when switching to VFOA / VFOB
5.Ability to change CW Delay
  Since it is fixed at 600ms now, there is a problem when communicating over 15wpm.
  You can change it with the radio dial, or change it via Hamradio deluxe.

6.Added Dial Lock function
  Because the encoder is sensitive, the recognition frequency will change sometime. so Added Dial lock function
  Press the function key for more than 3 seconds to lock or unlock.
 
7.The first time you press the CW key, it reduces the time to TX.
  However, we have added a function that can delay the transmission time of CW when switching to TX by CW key.
  When I tested it with my receiver, there was no big problem in transferring without delay (TX -> CW Interval).  But I implemention a TX->CW interval feature for personal choice.
  This may be useful when using external amp.
 
And more small modifications...

Re: Almost all of the firmware has been modified to fix known bugs and enhance CAT communications.

Ian Lee
 

Maybe this is the answer for you.
Farhan's code include 
default side tone : 800

and 
blow codes
if (isUSB)
si5351bx_setfreq(2, frequency + sideTone);
else
si5351bx_setfreq(2, frequency - sideTone);

but, original source has simple bug, so you can not change to sideTone.

if you use arduino ide with Farhan's original code (https://github.com/afarhan/ubitx), Please see the linkbelow (I posted a bug fix on SidTone on my blog)


2018-01-04 1:38 GMT+09:00 John Seboldt K0JD <k0jd-l@...>:

Does the CW tone function actually change the CW offset as well, so if you tune to the sidetone pitch you're zero beat with the station?

:-) Hi Ian Lee, yes the Raspberry Pi foundation often have a raspberry pie at their gatherings/celebrations ... Read up a bit, the Pi is an (appropriately mathematical) adaptation of "Python", the language originally intended to run on it as a learning environment.
For those not yet clued up on it, it runs Linux, with its vast repository of Ham Radio programs, and with its low power requirements the ideal for 24/7 ops (I run it that way for APRS).

It is made as simple as the picture.

I have put a PTT switch on my photo before I fully implement CAT communication, but I do not use it now.
The connection between the sound card and the transceiver will be easily found on the Internet.

Nice to just plug in the cable without having to open the box.

I'm starting from scratch, not having done any software for 25 years this will be interesting to get started.
I'm hoping the BITX Wiki has some guidance for getting a dev environment setup for a relative software newbie.
I suppose a virtual machine on my Win 10 box to run Linux will be a start?

A mini usb "breakout" would be nice for uploading new Raduino sketches without opening up the box. Could double as a CAT control interface.

I use the RD15HVF1 exclusively so i don't need to worry about multiple parts.  The gain of both parts is very close and they are pin compatible.

I would think they are a reliable source also.  Unfortunately they are no-stock on the RD16HHF1.  RD15HVF1-101 may work.  Anyone care to comment?

My assumption is RFParts is a reliable source.  That's where I've gotten mine.  Given my employment with a semiconductor company that makes (competing) RF parts, I rarely go near ebay.

Yes.  This part is particularly prone to fakes.  It would be helpful if folks could post both reliable and unreliable sources for these.

Careful with those $0.85 RD16HHF-1's
Often some random switcher FET with fresh paint.
Google "fake RD16HHF"

Maybe a shift to Mitsubishi RD16HHF-1 MOSFET is worth a try. ...  They are everywhere from $5 each here in the US to US $0.85 (China) in lots of 10.
