Good evening all. This is my first post here, but I've been lurking for a little while. Sorry if this has already been discussed, but... I'm currently using Allard's code (ver 1.24) and would like to

Yes. I have ano lm386 module from kits and parts

Hello I have the same kit and have a DDS built already. Is their a list of components that can be left out given I am going to connect the DDS. I dont need the on-board VFO. Thanks Laurence (KB1HKO)

I put mine a 1/8" endmill in my mill so I'd get nice accurate, straight cuts. Then I used a file to square off the rounded corners. Vince. -- Michigan VHF Corp. http://www.nobucks.net/

Whaddya mean tubes are gone?!?! My main low band rig is all tubes (old Collins KWS-1/75A-4) and I just picked up an old CB tube type amplifier that's being put back on 10 meters with an added 40, 20

Or send the headphones signal through another amp to the speaker when the phones aren’t being used. Another LM386, or one of the many inexpensive low power class D amp modules from eBay.

Hello Just joined the group so hello to everyone. I have the the Hendricks Bitx20A kit. I already built a DDS board to replace the on board VFO. I have a simple question. What components are needed to

There is another thread on here showing some examples of various bezels. I always use a nibbler to cut the square holes. -- John - WA2FZW

Like I'm sure many others have done, I salvaged an existing project box for mounting my bitx. Even using my Dremel tool, I always? find cutting rectangles for meters and displays a challenge to get

Allard's scheme works fb when using the headphones. My problem is the low side tone level when using the speaker, probably caused be the speaker impedance being much lower than the headphones. I

You might be better off just modifying the microphone to use an electret mic element. Michael VE3WMB

Martin, the calibration mode is normally only activated when pin A2 is connected to ground. However this pin is normally not used. Double-check your connections. Perhaps you have a short between pin

You might want to reconsider, Francesca - try FETs with Megohm impedances (pseudo-hollow-state?)- and even ordinary transistors go well below 500 ohms in common-base configuration.

I have Farhan's BITX40 V3 kit.? I am wondering if I can use my vintage Geloso dynamic microphone with it.? I know that I would have to use a capacitor to block the DC for electret mics, however the

My first rig was a homebrew 15W CW transmitter that my Elmer helped my build while I waited for my Novice license in 1954. The receiver was a Hallicrafters S40. I graduated to a DX-20 as my lawn
