Hi all, I have received the Bit X 40 for Christmas. What a wonderful TRX. Worked first up with great results. VFO is very unstable so I built another DDS VFO using an AD9850 and Arduino. I have built

I ordered two new BITX40's via PayPal. No confirmation yet. Jack, W8TEE To: BITX20@... Sent: Thursday, December 29, 2016 12:01 AM Subject: RE: [BITX20] Re: Tracking shipment ? I

I ordered mine on 12/23. The money was sent from my Paypal account. But no confirmation yet. The reply I got to my initial inquiry was to sent eh money and it would be shipped in a few days. I only

you can do it on air. with the bitx40 sketch running on the raduino, 1. tune in a station, ask for her exact frequency. 2. move the dial until it reads the correct frequency, by now the signal would

In the Si5351 library, there should be a calibration sketch (look in the examples folder of arduino app) Try this method; http://ak2b.blogspot.com.au/2015/02/stuff-i-learned.html

Ken Just printed it. Will test tomorrow Thanks 73 Art Sent from my iPhone

The PDF should instruct on how to use the sketch. 73 ken BITX20@...> wrote:

Ken Thanks. That's the one I have. Art Sent from my iPhone

BTW, the sketch is for the Adafruit SI5351 and nano. 73 Ken BITX20@...> wrote:

Ken Appreciate the help. I will check it out. The sketch I have is from the etherkit, examples. I think I don't fully what to do after compiling, uploading via ide, open the monitor and at that point

I do have a calibration sketch and instructions. I can upload to the Bitx files section. I haven't used it in a long time. 73 Ken VA3ABN BITX20@...> wrote:

Looking for a way to calibrate the si5361. I don't have a signal generator. Do have a freq counter. Read the discussion for calibrating as well as compiled the calibration sketch for the si5351 but am

Yeah; I forgot about that one. Thanks for reminding us. john AD5YE ---In BITX20@..., <jbammi@...> wrote : Or this more recent interview on QSO today with Eric 4g1UG, link below

Thanks all now ordered looking forward to it will keep you updated. Gary wrote:

Hi, I had ordered my bitx40 b4 the digital vfo. I emailed them, they responded: S Hope this answers your question. TF

No doubt, Jerry, I was just afraid that someone with less knowledge ( like me :) ) might order the 2n4148s without understanding the difference. 73 and thanks for advising. Sent from my iPad

. I found a calibration adjustment for the vfo, Instead of 27 mhz reference frequency, I adjusted it to 27010.050 which seems to put it almost dead on. I haven't really checked the transmit yet, but
