Ge again, Group 
I hope I can hear you guys tonight. 
My Frying Egg QRM has returned with the Cold weather. 
I have a bouncing s5-s7 qrm level. It is the strongest on 40 Meters, not quite as bad on 80m, and almost gone on the higher bands. I am pretty sure it's scamming in on my antenna, but it's too cold to shut the power off to see! 
So if I sound a little deaf tonight, this is why.

Curt-

Max-Gain Systems sells fiberglass tubing in various sizes and lengths.  If you want 'really strong', they carry solid rod as well.   From my experience with PVC, it's somewhat brittle at cold temperatures.  Disclaimer: no commercial interest.

If indeed the power cube is linear, and adequate in voltage and current - it can be tamed with a simple regulator circuit.  check the QST archives to see if you can find cube tamer article - no worries it is just a 12 volt regulator and some capacitors.

There is many different vendors that we get our washers from. There is no constancy in the thickness of the washers. It really does not matter, the only purpose of the washers is to space the speaker off of the board

Hi Jim,

Thanks I figured to match them as pairs on a side or top/bottom, not as you said not to opposite corners. I've done similar for grill cloth, I'll have to see what I have around for that. I have plenty of dark socks just not ready to be cut up ;-)

Hi Phil,

It's OK for the metal speaker frame to touch and make electrical contact with the ground plane that surrounds the plated through mounting holes.
But there are active traces that run underneath the speaker.
Those the frame should not touch. But they are sufficiently far away from the washers.

Given that you have a mismatched pair of washer thicknesses - don't put the like-sized ones diagonally opposite, since that would torque the frame.
Put them on adjacent screws.

I cut up old dark socks (after washing!) to make cheap "grill cloth"

Re: Bayou Jumper Power Supply

Bill,
  I know you reposted, but a general comment. Is that “wall wart” an old-school linear supply with a big transformer? If so, it is not regulated, and the “no load” voltage will be WAY over 12 volts! Check that before connecting it!

My BY jumper will mostly be used in the shack.  I have a 'wall wart" whose output is rated at 12V and 3.5A. Someone said the amperage might not be enough to power the transmitter.  I can't find any information, so I am asking this group.  Can I use it to both receive and transmit?

Re: Bayou Jumper Power Supply

John - KK4ITX
 

That should be quite adequate for power but I would first run it from battery power to compare "noise" from the Wall Wart.  I would use the wall wart to charge a battery and then run from the battery.  A 12v AGM or Gel Cell can be had for under $20 usually, I have 3 and use them for my FT-818...... don't know what I'll do for the BJ yet.
