Topband: 8Q7BM on Topband

2014-01-26 Thread Björn SM0MDG
Hi gang, I am currently on a vacation trip in the Maldives and are active in CQ160 with a very simple setup. I am using a 15 meter high top loaded vertical on the beach with only a few 1/8 radials on the ground/in the sand. I am running a TS-590S barefoot and don't have an RX antenna, so please

Topband: Conductivity of stainless steel hardware

I have been building antenna hardware such as transmitting chokes, Beverage transformers, etc. in various plastic boxes. The electrical connections have been to solder lugs fastened inside the boxes to stainless hardware. The actual antenna wires have been connected outside the boxes to the stai

Hi Charlie, This is one area where practice overrules theory. Yes, SS is not the conductor that copper is, but it's not bad, and since you're posting on the lowband forum, I presume you're interested in HF. At HF, and at less than megawatt levels, the environmental virtues of stainless make it per

I've used stainless plenty of times and haven't ever really noticed any problems, but I've never tried to make measurements either. My new vertical matching network I'm building using silicon bronze hardware to bring out the connections but that's mostly just because I can. I don't really expect

Some of the longest most drawn-out debates (and fights) come from dealing with how much is good, how much is OK, or how much is bad. It goes on and on with everything until our heads spin. <<< A very tech savvy friend (microwaves, public safety radio) says this is no good. Due to the poor cond

The primary additive in stainless steel is chromium - not nickel. There are some stainless steels that do not contain nickel at all and there are non-magnetic stainless steels. Another common additive is molybdenum. Charlie, K4OTV -Original Message- From: Topband [mailto:topband-boun...@

I expect that most of the offending nickel at VHF/UHF sites is nickel plating on less expensive connectors where it is used in place of more expensive silver alloys. Ch;arlie, K4OTV -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Charlie Cunningham Se

PZ1AA sent me zone "DX" and was very definitely south of my QTH based on antenna selection. CQ contest FAQ says "log the zone based on their location" if the guy sends wrong or no zone. Tim N3QE - Original Message - From: Don Kirk [mailto:wd8...@gmail.com] Sent: Sunday, January 26, 201
