So really the point is that I want the load to operate according to specifications:? VSWR 1.1:1 0-1 GHz; 1.25:1 1-2 GHz.? This one can't make spec above 30 MHz. Here is another picture of the

Typ, the local power company will give u a few gallons? of xfmr oil.? ?I used that in the heath dl....and also my HB? 8 gallon DL.? ?But neither are used above 10m. Mineral oil will work too,

First time I ever set foot in an SB-200 and it doesn’t look too complicated. But I want to make sure I have it squared away before returning to its owner. My buddy bought this for $200. It looks

In some counties Baby Oil is a mineral oil and suitable for electrical cooling. It is also possible to drain the oil from a discarded electric radiator which in my experience is similar but less

If all else fails,? you could just feed power into a 435 mhz ant, like a 1/4 GP / dipole / small yagi .....in the garage or basement etc. How much power does the DL have to handle? @ 435 mhz ????

Why focus on the ROS which hides an important parameter which is the reactif. Measure and show us the S11 with a nanaoVNA from 0 to 1 GHz. The variation on the Smith will tell you more than the SWR

I guess I should consider myself fortunate. I got a gallon of silicon oil from work. It is use to keep the HV electrodes cool that make ozone for our DI water system/PW500. I put it in my old Heathkit

I have never seen a price list for the spare load resistors for Bird Loads. I presume that the prices are horrendous. When I inquired about overseas shipping of the Bird Load Silicone oil, it was

Oh Man! I am looking very forward to this! I want one of these! Seems as if I am always either a day late or dollar short. Definately keep up the good work and keep the community posted. Can't wait to

if pushed hard on 80 and 160.. can and do arc over on the band switch and the wire that runs down thru the switch.? I have had to clean mine..

Never heard of a problem with the band switch....there are 9 people, in a group of u, that chat every morning on 75 and they/we all have 82's. This a new 'issue' to me. In any case, never had an issue

Best check the band switch prior to a sale, they are pretty much unobtanium at a realistic price. As far as I know you need to order direct from manufacturer of switch, they have a 5k minimum order

I am located in Reno, Nevada. I say this right off the bat as this amplifier I am offering for sale, is too big for me to ship, so…… I have a 6 year old AL-82 legal limit amplifier to sell. I am

Hmm... I've attached some pix.? The one thing that doesn't fit is that the silver fitting on the wide end/front panel fits that 3/4" copper pipe perfectly; it will not fit any known (to me) dimension
