I like that one jack I might have to get one.

Can anyone tell me how can I replace the tuning pot for a rotary encoder??? Encoders are more comfortable for me...

It's a great idea... I still waiting for my kit, but I'm looking for a convenient enclosure to work everywhere, at home, on the field, on my truck.... Pelican boxes are a great idea

Has anyone considered building their BitX into a Pelican box like this company has? The one they have isn't a BitX but the idea's there. The 1120 is going for about $30 (w/ free shipping) on ebay if you find the right seller - someone is selling all of the colors for that price.

K5BCQ has a kit called "Damm Reliable Attenuator".?? Get it with the switches with choice of BNC or SMA.

9 Stages.? What a nice kit!? Under $15.? Over 100 db.

Fun to build.? I checked out mine, it is plenty accurate.

Search for it.

Oh, I need the instructions to add a power supply, antenna, etc. to it. The ham that handed it to me had no paper items except for a half page of paper that listed some components.

I don't see a way to edit my previous post or I would have done that instead of making a new one.

Okay, don't worry about it then.

I would like some instructions and schematic. I looked through the files section here, but I'm not sure I got the correct ones.

Thanks,

Jim :?

The Bitx40v3 board came preassembled, likely that cap is the the one intended to go between wiper and ground on the tuning pot.?

See details at :?



Note that this figure depicts a 10 turn pot, but you want same setup from Wiper to ground on a regular linear 10 pot.?

cheers

No need for any of them. The parts are included in the event you want to revert to the analog VFO. The Raduino replaced the need for the additional componets.

Michael,

The IRF510 has a input capacitance of 180PF vs the 520 being about 360PF, so you may have to turn up the drive level a bit more, but the 520's should work fine. I have used them interchangeably and had very similar results with both.

I had asked Allard and group the same question. Very recently I uploaded v1.17.1. I had the anti-gallop switches but removed them when I updated. I set my bitx to tune the entire band (no CW) occasionally I still hit the bottom of the 10 turn pot (yes you'll need one) the radio gallops. My buddy kept his in and his doesn't gallop, but I seem to remember that it doesn't maintain the last freq set before we turn it off. You will need one of the push buttons for a function switch (orange to ground) and a 10k resistor soldered to the main board and in the black position of the Arduino 8 pin plug for PTT sense whick will prevent FMing. I'll send you the wiring photos.

Jim,
