Re: [Elecraft] Velleman AS9 mat for KX3

Aw, gee Alan. 1) Plus or minus 10% of say 10 Megohms simply means between 9 and 11 Meghoms. No negative resistance is implied or needed (but if you find one you'll be rich and famous!) 2) A solidus is commonly used in place of "per" so I read that as the resistance between two electrodes a

Re: [Elecraft] KXPA Power Output

As I said, that’s true if you occasionally drive high SWR loads. There’s no downside in normal operation. And with a supply like the Astron, if you accidentally overload it, all you need do is cycle the power switch. 73 Ron AC7AC From: Walter Underwood [mailto:wun...@wunderwood.org]

Re: [Elecraft] Velleman AS9 mat for KX3

I'm suspicious. Why are some resistances specified "+/-"? I'm pretty sure it doesn't have a negative resistance. And the units of volume resistivity are ohm-cm (or ohm-m), not ohm/cm. The fact that it doesn't specify compliance to any industry standard also is a concern. An anti-static

I see your points. I'm just a little more conservative (paranoid) than others. I like a little headroom. I've got a pair of RS-35M's that are 24 and 20 years old. I can't kill em. On 4/17/2016 6:47 PM, Ron D'Eau Claire wrote: A quality 20A peak supply is fine. For over a decade I've run a K3

Re: [Elecraft] KXPA Power Output

Glad that a 20 A supply works for you, but the specs say: "12-15 Vdc (13.8 V nominal), at least 24 A peak capacity. About 1 mA parasitic drain current whenever dc power is connected.” So for the least problems, make sure that your supply can deliver 24 A peak, not 20 A peak. wunder K6WRU

Re: [Elecraft] KXPA Power Output

A quality 20A peak supply is fine. For over a decade I've run a K3 and then a K3S and, when those aren't on a KX3/KXPA100 off of an Astron 20 without an issue as long as the finals see a decent SWR (current demand skyrockets as the SWR goes up). At low SWR's none of the rigs exceeds 18 to 19

Everybody is making arguments for why it can't be done. I'd like to hear arguments for why it can be done. Clearly someone (Elecraft and perhaps others) knows enough about the K3 and K3S differences and various permutations to do this. Remember when one had to configure xtal filters manually

People want to reduce the amount of button pushing to a minimum. Remember when your rig was new and how long it took to get the settings the way you wanted? Buy a used K3 or a new K3s and it takes some time to set it up like you like it. I absolutely hate swapping CD's and DVD's loading
