We can use Ian Lee's firmware for 1602 Display or Nextion Display . There are other firmwares but I have not tried any of them as yet . Regards Sunil vu3sua

I came across two units where the 45m15. Has deteriorated.agter changing them rig was restored. This could be of some help. Sarma vu3zmv

Very good! I hope you take a crack at the user interface as well [email protected]> wrote:

The fact that the SIDETONE is loud -- is a clue. Look and see where it gets injected into the system. Since everything after that is working, the problem is BEFORE where the sidetone gets

Have you tried replaceing the volume pot.... sure seems like its something close in there where you are poking it around, and a major symptom seen to be an inntermitant thing like a loose connection

Hi Richard, If the dial frequency is off, then do the full calibration steps in the video https://www.youtube.com/watch?v=t6LGXhS4_O8 This will also help with receiver sensitivity. 73 Evan AC9TU

Thank you guys, a brief update, and I'll summarize later into one message. But for now based on new suggestions: Probing, flexing the board, touching diodes, other components, BNC connector, etc.,

I shielded the 100 MHz oscillator and this reduced all noise issues. ?The oscillator is as spraying into the power lines.

Hi Sunil, I will be a customer for the RX kit.? When that is available I will place an order for at least two. I think it will be a great product. Thank You and Good DX ! Jim WB4ILP

Hello The version whether 3.0 or 6.0 would be the same to me. The frequency of the 2nd IF was changed once and the AF part. I would definitely try this as a double super with two conversions to 45Mhz

That's a good point version 5 or version 6. Well we made the version 5 diy kit which is working well. The receiver part of version 5 and 6 are same I presume . If I am wrong please correct me . But

Hi Richard, Have you checked your antenna cables?? ?It could be you have an intermittent connection on the BNC cable.? Try wiggling the BNC connection. 73 Evan AC9TU

These BNC antenna connectors are sometimes bad quality...

Ok. I missed some previous messages. Is it not continued, same topic? Anyway, Do You have the same level of noise/hum while touching core of antenna connector and pin2 of P2 (or, TP1, TP2)? Is Your

Hello Richard, 1) Without the scope You can easy check if last audio components are OK. (LM386 audio amplifier and Q70 preamp). If You touch 3rd pin of LM386 or base of Q70 with small screw driver

Are you planning on the V4 or V6? Do you plan for a waterfall display? As it is uBITX, I presume that it will not be an upconverting superhet like sBITX? Jon, VU2JO [email protected]> wrote:

We are in process of bringing out a receiver kit with ubitx design . It will have AM included . It will be a good standalone receiver. Any suggestions welcome. Best regards Sunil

Richard, D3 & D4 are together and D5 is a bachelor elsewhere! In another board there was a broken 10 ohm resistor on the BiDi Rx amp stage. Good luck. rak

Bernd, I have always been thinking of this option for a separate RX. Many times, one friend messages me that he is hearing a particular DX on one frequency on his uBITX loud and clear. But when I
