Just because a tech says it's a known failure today doesn't mean it's been a known failure throughout its production run.  Component availability and sourcing necessarily change over the years.  A robust component from a former supplier ten years ago may not be as robust from a different

My antenna is a TA-33-M-WARC. It's flat around 14.150, but goes up fast as you head toward .350. I have an FT-950 and FTDX-3000, and both need increased drive to get me to 500 watts. More concerned about the fault at 1.4:1. Although the two could be related. Anyway, the auto tuner handles

[Elecraft] KPA500 Question

I think requiring a different drive level is normal for most amplifiers. The K3S is the only transceiver that I have owned where the output can be set differently for each band, which is wonderful. My KPA-500 is pretty tolerant of SWR 2:1 or less however that may depend on the load type. What is

I occasionally saw this problem in earlier KPA firmware. It seemed intermittant and I was unsure if it was me or the firmware that was causing this - sounds like it was the firmware. I'm currently testing the latest 1.11 and don't see the problem at all. Be patient - I think the latest

Re: [Elecraft] KPA500 Question re the K3s per band power control

Many thanks to Fred, K6DGW, Paul, NF8J, Frank,W6NEK, and Tom, W1TXT, who responded to my post regarding this problem. They have all concurred that the K3 does not retain the dual power settings correctly when KPA500 MENU: BAND CHG is set to STBY. I'm now confident that Elecraft will fix this

What doesn't work is setting the KPA500 MENU: BAND CHG to STBY and expecting that the power out from the K3 will reliably switch to higher

I remember reading a post by someone at Elecraft (can't remember who it was) saying it was a timing problem (well, call it a bug if you like) which would be solved in the next FW release. Someone wrote on this reflector he already had pre-beta release 1.11 and no problem. Let be patient! 73 -

Re: [Elecraft] KPA500 Question re the K3s per band power control

Ken, All good points and must be done to take full advantage of the KPA's capabilities. The V1.11 threw me too. I have been communicating with Elecraft on a separate issue on the K3/PR6/KPA compatibility and they have noted the highest (Non Released) Version is 1.09.  I even checked earlier

I notice the same thing. I would love to have VFO B show the K3 power out when I change bands. Right now KPA500 and OPERATE of STANDBY are spelled out. They could be abbreviated leaving room for the actual power my K3 is going to make the first time I press the key. I'm always wary that

Only my 2nd day using it. Operation manual on page 8, item 4 under transmitting says you can have two power settings per band. One at any power you want one to drive the amp at the proper level. Assuming the radio is a K3. Which it is in my case. OK how is this done? I can't find any

Re: [Elecraft] KPA500 question

Hi r, See the K3 firmware release notes: http://www.elecraft.com/K3/k3_software.htm You need to have version 4.36, the accessory cable in place between the K3 and KPA-500, and CONFIG:PWR SET = PEr bAnd. 73, ~iain / N6ML On Sun, Jun 19, 2011 at 6:57 PM, r miles greenacres...@charter.net

Re: [Elecraft] KPA500 question

This feature is automatic if you have a K3 with firmware 4.35 or later and the KPA500AUX cable connected, or equivalent. The K3 will store its power level with the KPA500 in Operate mode and an independent value when not in Operate mode, i.e., Standby or power off. Ed - W0YK K9IL asked: Only

Re: [Elecraft] KPA500 question

This is done at the K3 so it's described in the K3 instructions. If you haven't already, you need to install Firmware 4.36 in your K3, and you'll find details for the new setting in the release notes with the firmware. Ron AC7AC -Original Message- Only my 2nd day using it. Operation
