2.2mH is a large value. I guess its purpose be protection against statics. 1uH has is a low impedance at MW providing some highpass but maybe not enough in presence of a nearby station. Try it in any case.

Lots of data here already. An AM station antenna is actually the very tall tower itself,  should be easy to see where it is. But you might have other interference sources there. If you can take your ubitx to a park with a battery and many feet of wire, see if it receives better there. Some have to enjoy their ham radio away from home because of interference. Do see if the bad interference at home is on every ham band.

Yes there are somewhat larger common 16x2 displays. I can't speak to 'direct' replacement, (not interested in doing that homework) but these have I2C modules and 6800 parallel library support.

Look at the datasheet and see if the size is what your after.  The rest should be simple software changes, if needed at all.

Hi M. LeBlanc,

I've had good luck shipping to Canada with Arrow Electronics.  They are pretty much an international company so they are used to shipping to/from different countries.

I'm in Ottawa if you need assistance with your bitx.

73,


Mark.

It seems the problem is mainly about soldering technique or general electrical repair.

One tip I have is to plug the female connector on to the male connector. Use quality solder and additional flux. along with a clean tip. 

Solder a pin near each end then move around so you don't heat them in kind. A bit like tightening lug nuts on a wheel.

Squeel and intermittent loss of audio v5

Maurice Bersan
 

Just a heads up if you have a v5 board and are using the universal case with the extra accessory board. The one with Ptt audio and CW jack's mounted on the front panel. I noticed with mine that occasionally when I plugged the mike in I would loose audio and had a loud squeel when I turned the volume down. Problem went away when I removed the mike.. after about an hour of head scratching I found the underside of the accessory board would come in contact with the threaded riser beneath it....the one on the volume pot side of the lower case, which is used to secure the front case stand. Just a minute amount of flexing of the front panel would set it off. I ended up grinding off about 1/32 off the riser for clearance.
Cheers

Re: Using Vacuum Tube heathkit as Linear Amplifier for QRP

vu2pep, how did you do this? How did you connect the bitx20 to the
DX-60? I want to try the exact same thing with my uBitx and DX-60B.
Did you plug the output of the Bitx into the crystal socket or VFO
input? This is a new adventure... -- 73, Rich WB2GXM

Is it that hard to solder in the pins?  Those gold plated ones take solder
very well and its not hard.
