Forgot to mention, it's serial # 133/5? so they must be in the 5th batch now.? It does have a socketed UTC audio chip. W0EB

The ubitx wants to see a low-impedance drive from the mic, comparable to a 600 ohm impedance or thereabouts. The D-104 crystal element presents a 50K ohm impedance, and the amplified D-104 presents

The Raduino has been spoken for. There may be another one available (same deal) early next week and I'll post that if it happens. Jim - W0EB

I have a never used Raduino from a Micro BITX (not a BITX40) complete with display just as it came in the box from India.? $30 US plus shipping ($8.00 US, $15.00 International). Please "reply to

My ubix is still MIA ordered 26/03 no trace of it been shipped still waiting for it to be sorted out :(

I can do anything with the shear.....still waiting for the dust to settle on this overall design. Just bought a qty of NXP 2N7002P parts. 73 Kees K5BCQ

AGC and Pop fix want to be in different regions of the board, and they are both operating on low level signals. They might agree to be in the the same envelope. Perhaps have the builder nip the PC

Yes indeed. Mine must have been in there right along with yours. It made it to Romulus Michigan this morning and is now out for delivery.

Hi both, 4.7k pullup resistors fitted to Raduino board as instructed. There is now 5 volts at the encoder pins A & B, which varies 0-5-0-5-0 as the tuning knob is turned. This makes no difference,

1K. Change one or the other, not both.

If R63=24ohm what value should R65 be? [email protected]> ha scritto:

Skip: I didn't touch R65. Changing its value changes the DC operating point at the collector of Q6. R63 has almost no effect on that, since the current is set mostly by R64 which is bypassed for

I recently ordered a MAX9814 mic preamp board with AGC. on eBay for $3.32. I will post about how it works after I get it and test it. Howard WB2VXW

Howard did you also change out R65 that was posted here too. By the way the parts showed up here yesterday, thanks a lot. Now to find time to install them. Skip Davis, NC9O

I use the Retevis mic. Under $7 on eBay. I cut off the connector and rewired it to the phono jack. Despite what others have said about the wire colors, I found Red it the mic, Black is ground, green

Yes. Change R63 to 24 ohms. The earlier rev boards had 100 ohms there, and V3 has 47. I put another 47 ohm resistor in parallel with the one on the board. Now I don't need to yell into the
