Never had an issue, but Ham City is poor. See my post above.

Frank, yes, that's the card I have, exactly.
Thanks to everyone for their replies!

Ordered a HY-Gain antenna. After 3 weeks they never shipped. I found out they do not stock and drop ship from MFJ. DX Engineering has the antenna in stock and are closer with less shipping balancing out the slightly higher antenna cost.

I am using a HK oil filled paint can dummy load, I'm at work so I don't have the model.  I don't know the age of the tubes other than the operator went SK at least 10yrs ago.  The tubes are very clear and once I had the right AC voltage in they lid up really nice and bright.  I only tested on 20m this morning.  Now it is possible the HK meter is out of calibration.

 Capturing human anecdotes and impressions regarding what people actually perceived during their radio operating experience might be as valuable as the more readily measurable data.

That approaches a point I was trying to make. Steve in Okinawa also made it--I think in a better way.

When you refer to data as "more readily measurable" I think you are inverting the process. As Steve points out, useful data collection and analysis requires a great deal of observing, trial-and-error and analytical thinking first.

If you are not familiar with accepted experimental design and statistical methods your "measurable data" won't be worth much at all.

Cool, with all that being said, now is it ok to ask hams what their impressions were of solar activity and man made noise in 1958 vs 2016? Smiley

I am getting around 800w out with about 30w in with grid and plate readings well within spec.  At around 85W in the output is a whooping 1500+ out, I dropped it down to below 800w once I saw how fast it climbed. 

Glad to hear it's running, but those output levels are not possible with an SB-200. With fairly new tubes you should see approx. 600 watts on most bands.

 Are you using a dummy load?  What make/model of wattmeter are you using?

Another question on this antenna, has anyone upgraded to the higher power level with the kit from Mosley?

That is logistically impossible as the shack is in the cellar with no entry point (window or otherwise) large enough for the ladder line to come inside....that's why I am using RG8 Mini....




I'm using twinlead to my loop antenna, and where it passes through a small hole in the wall I just
splice in a short length of two parallel pieces of hookup wire.  They can be twisted together or not.
That takes up no more size than RG-58 (depending on the wire size you use) and since it is only
for a short length (less than a foot) it has little effect on the antenna.  Teflon insulation is a good
choice in case there are high voltages at that point.

At another location I ran two separate pieces of high voltage test prod wire in through the mesh
of a vent screen and spliced it to the open wire line on either end.

It may not be ideal, but both cases allow me to bring twinlead to the tuner in the shack.

I have a large collection of Motorola land-mobile VHF/UHF and Micom HF two way radios. Over the course of time these get chipped and scuffed up as they come to me through surplus purchases. I would like to repaint the metal chassis on many of the radios to restore them to "like-new" condition.

They are all black-cased radios with a slightly pebbly satin-like finish. I read where someone had found a company in LA that used to make touch-up paint for Motorola (they saw pallets of paint with the Motorola logo on the cans in a warehouse). Black was not one of the colors they listed.

Does anyone know where or what the paint is? I would like to get a few cans of it. I do not do enough painting (nor do I have an interest in getting) to warrant the use of an air compressor and sprayer.

The nearest I can find would be Plastikote #217, black wrinkle paint for use on cars in under-the-hood areas. That should be durable enough for a radio chassis.

Any suggestions?

Ms. Tisha Hayes, AA4HA
