Here's the emitter, collector, and base readings.? There was a question elsewhere about my meter, so I thought I'd document the process for those concerned. :o ? ?? Mike keyed w/ no audio. Extra

I added an external DSP noise filter to my bitx40... it has awesome AGC built-in, and can really cut back on noise without garbling voice (as long as I don't turn it up too far).? The audio out is

Bruce Thank you for asking questions I did not explain. Version 1.12 is just a conversion of Version 1.11 to uBITX V5. It supports both V3 and V4. Because it is the same source. As you can see from

I have looked at a lot images for many creative ways people have made a case for their bitx-40s, very cool! My radio kit will arrive tomorrow, and I am starting to think about a nice case - I probably

Ian, you may have already answered this and I missed so please excuse this query. I notice that this release is 1.12 and I assume (bad thing to do) that it is targeted only for V5.? V1.11 appears to

The circuit I tried is the simplest possible. A voltage divider 1.5K/220R followed by a 1N5711 and decoupled by 0.001u, (almost) identical as on the K2 (see schematic, p. 146

The AGC issue is part apples and part oranges. Some AGC circuits work off the volume control while others work off the IF chain. If you're using the IF chain, chances are there's going to be some

I mean what I said. ??/g/BITX20/message/26492 A search in the group webpage at? ?/g/BITX20/messages will find plenty of hits for both Q13 and R141. Jerry

I too was hoping to find answers to this same question. ?I have looked through Sunil's documents and I think the question above needs clarification. ?We are interested in how/where to connect the

Excellent! Thank you so much, Dr. Ian. Would you be OK with me submitting a file to the repository here for others, compiled for the 7" Enhanced?

Quote "Limit the power supply to 12 volts, anything more than 12v and Q13 and R141 will run too hot and can burn out." unquote. looking at the schematic, it looks like you may mean Q14 and not

He could directly measure across base and emitter and tell the reading ?

3.8V Base should have 3.2 on Emitter or something is wrong if there is 1Vbe.

Yes, I have a "junkbox". Some would say it's that 2 X 3 X 3 metre radio room I use for expressing cuss words from the blemish above my shoulders. Anyway - After working on this again today, I

Bill The stock firmware behaves relative to how fast you turn the knob. Try tuning very slow to see how it behaves. As I tuned I would get a bit excited and speed up to tune in a signal, no this does

Hi, Dr Lee. My V5 should arrive any day now, and I'll be happy to fiddle around with the basic program. I may not do much in modifications of the hardware at first but it'll get a workout at

If the system is same, I fear, it may not accept when sent by others either.

Ted The firmware for V5 is almost done. I am going to experiment and release some more. If you have V5, you can download the beta
