I have no clue why that didn't work as expected.? Are you sure those are real BFR106s? uBitx V3: Q10,11,12 are RX.? Q20,21,22 are TX.? In V3 schematic uBitx I cannot find a Q23? Since your part

I just changed Q11,Q12,Q13 and Q21,Q22 and Q23 to BFR106s and I've got the feeling the reception got worse. Before I start putting in the 3904s again - did I just forget something? Should I also

Jon KZ1G With careful choice of resistors in a resistor network keypad encoding scheme we get 1023 / 16 = 75.18 steps between each key value. Then by using if-statements to convert the key values into

This is what I see:

That's strange, I have the pictures on the one I received. It is also in the thread on the website.

Thanks for all the testing Rowland. It sounds like just attaching the AGC board to the coax coming from the volume control is enough to bring in the RF. Even de-powered. What are you using to connect

That would probably work, but I don't really need anything that elaborate. I think a fan with some ferrite beads on it will do. Jack, W8TEE

I scavenged a heat pipe system from a laptop.? It has a pad that was in contact with the CPU, and a set of fins that were ducted to the fan. Is that what you mean?

Hi Don -- here are the results of my test: 1)? Unplugged AGC board from main PCB.? Jumpered the header on the main PCB.? Left all wires connected to the AGC board that was now "hanging in space"

I did not know what it was called. Still, at $472 (smallest quantity I found), I'll probably stick to a small fan! Jack, W8TEE

From Howard's post I only see two do not enter signs. I see everyone else's photos but not Howards?

3M used to allow anyone who wanted to do so, to experiment in their labs. One guy invented a liquid that had unique properties, including letting animals "breathe" in it completely submerged. Also, it

Texas Instruments also has a programmable I2C I/O expander that lets you configure eight pins individually as inputs or outputs.? See TI part no. TCA9534A.? You already have an I2C port, so the

Hmmm...maybe power the RF PA section through the Peltier device with a heat sink on the outside of the case and another one with small fan on the inside of the case to stir the cool air. 8-) Arv

We grappled with the same tuning issue, especially since we were using an encoder push to change the tuning increment. Our experience is that once the rig is "set up", the most common actions are

Probably a higher power draw than I want. Jack, W8TEE

Hi Bill, I finally connected my computer sound card and started Spectran to serve as my CW filter. I works great. But! I had forgotten about the processing lag. When I tapped the key the dit didn't

How about the Peltier Cooling Device for an idea. Exhaust the hot air through a check flap/valve idea 73 Larry WA9DOH jjpurdum@...> wrote:
