This is a puzzle.You say the Amp sees infinite SWR ? Do you have a dummy load? With the Amp fed directly to a dummy load with a known good coax, it should switch to "operate" and feed power to the dummy at an SWR of 1.0:1 If this is true, seems to me you have a problem "downstream" of the

Re: [Elecraft] KAT500 Auto or Manual

Kev, Put the KAT500 in AUTO mode and then let it autotune with a constant CW signal (the ATU TUNE will produce the right signal) every 50 kHz across each band of use and for each antenna. Then switch it to MAN mode. The "problem" is mostly in SSB mode, but can also occur in CW mode. The

[Elecraft] KAT500 Auto or Manual

Hi: I'm the one that recently reported problems with the KPA500. I've replaced all RF cables including the one out to the BALUN and the BALUN itself. I know which bands are less than 10:1 in bypass and locked out bands that exceed that SWR. Something in the amp just refuses to switch from

Re: [Elecraft] KAT500 actual radiated power during tuning

Another thing to consider when trying not to QRM others while the ATU is tuning:  The signal can be pretty broad when the relays are switching. 73, Scott K9MA -- Scott K9MA k...@sdellington.us __ Elecraft mailing list Home:

Re: [Elecraft] KAT500 actual radiated power during tuning

Erik, I think your question has been answered, several times ... as I said once, and will tell you once more, my KAT put 25 W into the antenna connector when it had finished tuning.  While it was tuning, the power varied.  Note:  25 W in with it tuned yielded 25 W out [less losses my power

Re: [Elecraft] KAT500 actual radiated power during tuning

A technique that works well using a dummy load to adjust a tuner is to set up a bridge configuration where the dummy load absorbs the power and the tuner is used to balance the bridge.  Once done the dummy load is switched out and rig drives the tuner.  Electric Radio use to sell a bridge like

Re: [Elecraft] KAT500 actual radiated power during tuning

My KAT500 [when I still had it] put out variable power levels while it was tuning.  When it was tuned, it put out the TUNE power [25 W] into the antenna.  More than once, someone called QRZ? after tuning in a clear spot.  They probably saw my little signal on a fairly dead band on a

Re: [Elecraft] KAT500 actual radiated power during tuning

Erik, I don't know the workings of the Icom tuner, but the KAT500 needs 20 watts input to tune. All of that goes to the antenna. If part of that signal would be shunted to a dummy load, I don't think it would be tuned to the correct antenna impedance. I would have to know more about the

Re: [Elecraft] KAT500 actual radiated power during tuning

I understand the requirements, and the ICOM IC-7300 puts out 12.5W by default (can be adjusted via service menus). I'm looking for a definitive answer as to the actual radiated power. Like I said, the ICOM AH-4 tuner specifies its actual radiated antenna power but the KAT500 does not so

Re: [Elecraft] KAT500 actual radiated power during tuning

Erik, The KAT500 relies on the transceiver power being reduced when tuning. I am not certain how (or if) that happens with an Icom transceiver, but the KAT500 needs about 20 watts for reliable tuning. That can happen automatically with the K3/K3S/KPA500 combination, but I don't know what the

[Elecraft] KAT500 actual radiated power during tuning

When tuning using a KAT500 from an ICOM via an AH-4 interface what is the actual radiated power out the antenna? I was reading that ICOM's AH-4 tuner itself takes the input power and splits it into an internal dummy load and only radiates something like 300mW out the antenna, is the KAT500
