The idea is to have connectors at certain places where you can experiment with a wide variety of agc and other circuits . It would be fun to try different circuits and combinations and see what works

I thought I posted this yesterday, but don't see it.? Apologies if this is a duplicate. It appears (to me) that the way K3 is drawn in the schematic is misleading.? Shouldn't M2 and M3 be connected

Hello Bernd, I took the uBitx V6 schematics and crossed out all parts, that are not required for a receiver, to give you an idea on the complexity reduction. -- 73, Joerg - DB2OO

1602 displays are much cheaper although you do not have refinements such as downfall for band activity display as on the Nextion etc Consider having the display switching off after a predetermined

Have you considered such things as an RF amplifier, rf derived AGC etc Regards [email protected]> wrote:

Thanks Jim . I appreciate your support . The pcb is about ready but some final add ons are to be added to finish the pcb. Best regards Sunil vu3sua

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...
