Hi all, I have done some experimenting with RFSIM, modelling the existing BPF, and analysing it. I have come up with an easy way to have some filtering, without just shorting out the BPF. If you put a

Hi all, Extreme newbie here. I recently received a BITX40 and installed the pavelmc sketch from?https://github.com/pavelmc/bitx40 ( https://github.com/pavelmc/bitx40 )?.? I added a function button

I know it sounds simple, bit like me, but can someone detail a diagram for me. As I have fitted a socket for programming the Raduino, without removing any connectors and dont fancy frying anything,

Joe, ?? I have taken mine to a few places had a great time with it cw/ssb/digi. I did put mine in a metal case and use a pelican for travel it fits pretty tight and has some added weight but works

Mike, K8MGB and myself, KO8S, both in Warren, MI, were on 7.277 just before 7:00p local time for about 1 hour and heard no one.? de Karl, KO8S

Raj > is correct. One or 2 ma on the newer LEDs is usually bright enough. I go I buy all my resistors by the hundreds. At Tayda they're only a penny or less each. Doesn't cost much to have a good

Also, the voltage drop across led changes depending on current. we cant take 3.3V as only white led has that voltage. As I did not read earlier posts, i really don't kmnow whether the om wants to use

The Nano board has a diode that prevents your PC from getting fried. After a raduino fry up! there was a short that smoked that diode in the nano and I pulled the plug in time and that got me thinking

I buy 1K and 10K by the hundreds.? So that's what it gets.? Buy the way, Raj is correct.? One or 2 ma on the newer LEDs is usually bright enough.? I go 1K on 5V and 10K on 12V for some reason.

I have that diode on all my RaduinoX boards.? The other thing, I have left the 12V on my test fixture on many times while programming with the USB (by Mistake).? I have been Lucky.?? I? know the

My rule, for 12v I will use a 12K resistor for LEDs. Considering todays LEDs brightness I must increase that value.

I did that on an old (1.09) Allard Version.? I made a tuning function with the same name as he has. I can switch back and forth with the conditional assembly. It works but I don't get any of the

Allard :? The only way I could see that you could cram in support for an encoder for tuning would be via conditional compilation.? i.e. something like :? #if defined (ENCODER_TUNING) ? ?// code

I posted this question to another forum and didn't get much support for the idea, so I figure I'll ask here: "I'd like to get involved with some of the OTA groups -- Michigan's three year Parks On the

Folks, This morning I was working on a bitx with raduino. While connected to the PC for uploading a sketch I noticed the board was still receiving a station albeit at a lower volume. Then it occurred

2K2 for Red LED

Hi, I discovered a bug that the carrier burst is still not properly suppressed in CW-SPLIT mode. Normal (non-SPLIT) mode works OK. I'll correct that soon. 73 Allard PE1NWL

Yes it would. One of?my most important design criteria for the Raduino code is that it shall always work, even on a standard unmodified BitX40 (which uses?Ashhar Farhan's?tuning concept based on a

Hi, I think, You need to solder and test pcb's for transceivers, before publish them. 73!LZ1DPN
