Ge All 
Tough bands conditions tonight. 
On top of all the QRN the QSB was horrible on 40 and we had another net move in almost on top of me on 80 Meters. 
Well other than all of this it was FUN!

Re: Insulator for Ground Mounted Vertical Antenna

Suggestions appreciated - some of you have heard my 80 or 160m signal on the verticals - the taller one is still QRV.  don't have suitable trees hence these radiators.  these things have elevated loading coils and are top heavy ...

I see I can get about 4 feet of fiberglass rod for $9.30 - enough for several insulators from MGS4U.com  Now I just need to fill my shopping cart to offset the $11.30 shipping - which I think I can do.  I think MFJ charged me a lot more than that when I bought 2 insulators. 

I added on EFHW primarily for 80m SSB - but it wasn't doing 40m so I just shortened it by about 4 feet - so I can be QRV on 40m until the vertical is vertical again --

Check out McMaster-Carr.   They have a very large selection of material and any length you might need.

Ge Guys 
I agree with Dave, 
PVC is very brittle when it's cold out side. 
Also the White PVC will get brittle in the sun. 
The Grey PVS for Electrical work is the best for out doors.

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.

Re: Bayou Jumper Power Supply

Curt
 

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 

Good luck with your build

I found four washers two are 1.25mm thick the other two are 0.75mm thick. All are metal so this will not protect the speaker frame from being connected to the traces in the holes. These holes are grounded.

Questions:

 2. Is the speaker case supposed to be grounded? The instructions say, "...washers between the speaker and the panel to space the speaker from the frame up from the traces that run on the surface..." Metal washers won't stop the speaker from touching the grounded hole traces.

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"
