Si5351 calibration
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

Re: Damage to SMT version bitx40 from nearby transmitter
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

Re: A more stable Bitx40 (fun with ceramic resonators)
The 4.92 MHz resonator with C94 & C95 not removed gives about 4.8 MHz. The problem is that there's little variation since the varactor's capacitance swing is masked by the 100pF. I give some ideas

Re: Tracking shipment
Yes I did, but I initiated the transaction and so it may have confused the situation. I'm still curious if anyone has gotten shipping confirmation after ordering the new model. It simply may be that

Hi Roy, did you send them the extra 14 dollars necessary for the new model as this may be what they are waiting for (original Bitx 45 dollars, upgraded version 59 dollars) ? 73 Ian DJ0HF/G3ULO Am
