Re: [Elecraft] Wire size for the ground on the KX2

Good to know! My K2 no longer has the KPA100, but I still have the BNC Tee on the antenna. K3 does as well. You can calculate the required resistor size [watts] with a little arithmetic. I've used anything from about 56K to 220K, whatever I find in the junkbox. When us "old guys" fried the

Re: [Elecraft] Wire size for the ground on the KX2

Skip, Yes, I believe that later Elecraft products do have a static bleed or other static prevention across the antenna connections. BUT for K2 owners, that is not the case. The original KPA100 design had a 100uH RF Choke across the antenna terminals for just that purpose, but the latest

Re: [Elecraft] Wire size for the ground on the KX2

Fred, I guess that I was making the assumption [not good!] that the input would be protected by a gas-tube discharge device, such as those made by Alpha-Delta --- I try to always use one of these at the input of any radio. Of course, what is still needed is to discharge the excess charge, and

Re: [Elecraft] Wire size for the ground on the KX2

But be wary however. That, in itself, may not and often does not offer any protection at all. Each little charge from rain or snow static may be minuscule, but they charge the input capacitance of the device in the radio and eventually it breaks downbetween the input and the chassis. Just

Re: [Elecraft] Wire size for the ground on the KX2

Jim Brown, Another reason for connecting a ground wire to ‘mother earth’ would be a variation on your reason, and that would be to provide a means to discharge excess charge (‘static electricity’) before it can damage your equipment. This buildup of charge can occur if the antenna is

Re: [Elecraft] Wire size for the ground on the KX2

Wire the same size as your antenna wire is fine. This is carrying RF currents, just like the wire in the air. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 16, 2017, at 4:41 PM, Eric Swartz - WA6HHQ, Elecraft > wrote: > > Its a

Re: [Elecraft] Wire size for the ground on the KX2

Use what fits. RF current will be on the surface which scales as r-squared. Obviously larger diameter make more surface area. If you're in the field, use what fits/what you have. You'll never notice the difference, ANY wire is better than no wire. It's really easy to fall into "Picking fly

The speaker wire I use is the insulated flat stuff ~16 AWG equivalent.  Rolls up into a nice small ball.  I put a alligator clip on one end and a ring terminal for the KX3. Mel, K6KBE From: Michael Walker To: donw...@embarqmail.com Cc: "Elecraft@mailman.qth.net"

Re: [Elecraft] Wire size for the ground on the KX2

If this is for an RF ground, you'll need bigger than 22G for it to be effective. Braid would be preferred. Mike va3mw On Thu, Jun 15, 2017 at 5:25 PM, Don Wilhelm wrote: > Mike, > > I would use #22 teflon insulated wire. Teflon because it is 'slippery' > and that can

Re: [Elecraft] Wire size for the ground on the KX2

Mike, I would use #22 teflon insulated wire. Teflon because it is 'slippery' and that can help with wire tangles. Thinner wire may be lighter weight if you are weighing fractions of ounces, but it is quite durable. Anything thinner becomes more fragile. IMHO that is a reasonable
