Re: Grounding rods
You don't need to inspect "wire to rod." They are either welded or high compression crimped.

Concrete that yields to strikes has other issues. Consider that in nearly every case, a tower has a pin or other structural components that conduct embedded power. Matt AL0R -----Original Message-----

Re: Accessory connector on back of TK8302
Yeah, you're correct, the link will be on for two. Now, I just need to keep the three radios straight so I don't use the incorrect one that's not program lol. I'll UHF all the same model.

Re: Accessory connector on back of TK8302
And since it is a link radio, he probably meant "Port 2".

Re: Accessory connector on back of TK8302
开云体育No, didn't touch the board. We got it working tonight, we programmed the pins and found out that the Kenwood mobile radio does not have enough drive going into the controller so I had to disable the LED panel on the front of theArcom.

Re: Isolated Tee
Use a little baking soda and water. Make a paste. Use a toothbrush (maybe your wife's) and use that paste to clean the tarnish. It works well.

Re: Isolated Tee
Iso-tees can be made easily. QUALITY brand like amphenol or something purchased from Tessco. They are also on ebay used. Look for ones that are cleaned, that'll save time from cleaning tarnished ones, unless you have a couple hours or an ultrasonic cleaner. I used a low speed dremel/rotary tool and ball end carving bit. The key is slow (5k RPM) and low pressure until enough has been milled away. A dremel drill press and mounted vise make the job a pleasure.? -> 2mm gap between the center pins is plenty. -> DO NOT USE COMPRESSED AIR. Wash out with electronic parts cleaner. Measure insertion loss with VNA or spectrum analyzer with tracking generator for each band and document. Tip - do not buy connectors or coax from TEMU, Amazon, alibaba, whatever. Too much counterfiet junk. Cheap connectors cost more than you know. Just do the job right the first time. It's less expensive that way.

Re: Accessory connector on back of TK8302
