Thanks Chuck. I just don't want any extra loss. I was thinking last night, if I switched to hardline or RG213, I probably would still have the same S Meter readings. 73, Patrick Patrick Martin KAVT Reception Manager ___ IRCA mailing list

Russ, I have always used that method is testing the coax as it is the best way with just an inexpensive ohm meter. I also will test across the conductors to see if there is any breakdown between the two. But I did forget about the ohm meter adding resistance to the circuit and the error amount.

Chuck, Thanks. I did not know the fiqure, but I thought it would be less than 1 DB per 100 feet at 1 MHZ. Less than.5 DB is really a non issue. hi. 73, Patrick Patrick Martin KAVT Reception Manager ___ IRCA mailing list IRCA@hard-core-dx.com

Rick, That is a nice piece of gear, but a bit spendy for me. The A-B test between a new piece of coax and the suspect is a lot less money. hi. Now especially since I went ahead and attached the banana plugs to the RG59. I can easily run the coax out the door to check any issues. 73, Patrick

I have been checking out all of my RG6 this Summer with an ohm meter. I have found with 3 pieces of the coax (SW EWE,WNW EWE, and 1500' beverage) that the coax is a hair leaky. Maybe because of the age. 90% of it runs under the house for the SW EWE and beverage. Using an ohm meter in the RX1 scale

Craig, Thanks. Well, after I posted the message, I put a couple banana plugs on the end of the RG59 and ran it out to each of the three antennas. I did A/B tests on two locals (KSWB-840-Seaside, KAST-1370-Astoria) just before dark. KKEE-1230-Astoria was getting too much jumble in the signal so

My inclination is to leave it be. At MW the losses will be insignifcant in my view. Propagation and noise levels are more likely to be issues. I would look at changing it out in the next season or so. If you were at higher HF or so, it would be a concern. You're logs are a testament to your
