All CAT Support uBITX Firmware CEC Version 1.04 Release, but?There is no major change compared to version 1.03. I released it for people looking for HEX files. *The changes since 1.01 are as

There is no phasing issue with a bridge HAve a look at page 4

B40, nothing. I accidently gave mine 20+ when a regulator shorted in the worst possibly way. No damage done. With that audio chip I'll be using a much better regulator! Although I may replace it

Having the NANO board indicates that your BITX-40 is the later version. Earlier version with analog VFO is identical except for the VFO. _._

Ok.,Philip-my mail is :yu1km1010@... Mni tks....73 de YU1KM/qrp,Miki,Belgrade.

You could just drive both amps in parallel instead of bridge, this would avoid the phasing issue. But connect an amp output to the ring terminal will still burn it out if you plug in a mono plug,

Hello Jerry, My bad, indeed on the probes there is a lttle switch and the one I used yesterday was indeed set to 10x. So the mentioned voltages should indeed be 10 times higher. That would make more

I am playing with different raduino replacements, and some require a different digital wiring harness. As I do not wish to continuously solder / resolder the encoder, I wish to get some replacement

Hello, Sarma. What would blow first if someone plugged a 19V laptop supply into the ?B or B40 power jack intended for 12V?

Walter, A single heatsink is fine, but ensure you are using transistor insulating hardware. Marco - KG5PRT

Is it ok to put one large heat sink in for both IRF 510's or do the heat sink have to be separated from each other? Thanks for your help -- 73, W9KJO Walter

Thanks Arvo. Again I wonder whether our friends who had this failure mode , applied any regulated 12V or using 12V or 12-0-12 secondary trafo , rectify, filter and use ( a peak if almost 18V- 1 or

You can make any pin work with an interrupt using the attachInterrupt() function. The Uno and Nano only have two external interrupt pins (2 and 3), but the rest can also be used for interrupts.

?Although i don't do it often, we have FLDIGI on about 8 raspberry pi's in our local ARES group. Gordon ________________________________ Sent: Monday, March 5, 2018 7:57 AM To:

Hello, Sarma.. There were reports of these WX devices failing spontaneously, without any short circuiting. The simplest explanation is that hfsignals ordered a batch of TDAs that are not capable of

I have a Pi3 that runs Fldigi with no problems.? However RMS Express will not run on a Pi.? So I abandoned the Pi3 for a laptop.? My laptop, running Win 7 will run indefinitely on my solar system

We are genera;;y habituated to listen thro both the ears. Thus the style to listen to mono symultaneously on both ears. Otherwiase one ear remai\ns silent to radio listening. iMHO the whole issue

If you have the 16x2 LCD displaying the freq, etc., then you have the Raduino. The toroid is not required. 73 Ken

That's great.? Thanks! Chuck, N1KGY
