[Elecraft] K3/100 low power setting "gap"

Dear all, I have a kind of luxury problem concerning achieving output powers in FSK between 9.5 and 13W. The setup: a relatively new K3/100 with the last firmware a recent TX gain calibration. I'm doing a lot of RTTY, mostly in submode FSK D. Now I hooked up a 1K-FA linear amplifier which has

Paul, Wow! Many thanks, I didn't realise it was simply an oversight, and not some basic limitation in the way the hardware worked. If you would like me to beta test the new version I would be happy to do so, especially as we have good auroral conditions just now and that is where I use RIT a

Re: [Elecraft] Unplugging the radio to protect it

Do I disconnect every cable? No, just Coax at the radio and power strip from the wall (which disconnects all else). The ONLY connection I don't have the ability to easily disconnect (which I'm trying to figure out) is station ground. To date I've never lost a piece of my station gear and we get

[Elecraft] Unplugging the radio to protect it

I had an experience a couple weeks ago where the USB audio chip in my Kenwood stopped working. Kenwood service refused to fix the problem under warranty and blamed me for not unplugging every single cable to the radio when not in use. I had only disconnected the antenna. Not the power, USB, key,

Re: [Elecraft] Unplugging the radio to protect it

Very few hams, if any, disconnect EVERY cable from their rig when it is not in use. Having said that, it's certainly a good idea to have a common grounded entry point with suppression devices for power, antenna, phone, cable, etc. so there won't be potential differences between equipment in

Re: [Elecraft] Unplugging the radio to protect it

I would suggest you read the manual and the warranty statement. I don't think you will find a disclaimer about removing all cables from the radio when not in use. Mel, K6KBE From: Vic Rosenthal 4X6GP/K2VCO To: elecraft@mailman.qth.net Sent: Thursday, October 8,

No, I don't disconnect *every cable, usually just the antenna coax as itenters the shack (which, in NC, is in the basement and a coax feed-throughcomes through a concrete block and brick wall, and the disconnect pointis at the wall, 4-5m from the equipment). All equipment (except handhelds)is

Maybe they're relying on one of the sublaws in "The Contributions of Edsel Murphy to the Understanding of the Behavior of Inanimate Objects": " II. 3. All warranty and guarantee clauses become void upon payment of invoice." That being said, I think one of the factors in Elecraft's success is

Re: [Elecraft] Unplugging the radio to protect it

Peter, When I am away from home, I disconnect all antennas and unplug my power strip. When home I leave everything connected 24/7, except when there is a storm or threat of a storm. Then I disconnect antennas and my mains power strip. If that is Kenwood’s approach to customer service, I am

Re: [Elecraft] Unplugging the radio to protect it

It is not normal to completely disconnect a piece of station equipment like a transceiver when it's not in use. Some disconnect the antenna, but I don't. I've had K3 #24 since 2007, and the only time I worry about disconnecting is if there is convective weather activity like thunder or

I do not unplug anything when not in use. Never had a failure from doing that. I do live in a virtually lightning free environment but static buildup in dry winter winds can happen. This is why having a shorted RFC across antenna lead -in or back/back diodes on RX input are used. System is

Re: [Elecraft] Unplugging the radio to protect it

Having done warranty work for Kenwood, both on commercial and amateur products, they are very "fussy" about warranty policy. From experience, every "I" and every "T" must be dotted and crossed, otherwise they most likely will reject a warranty claim. Now, there are others, such as myself,
