[Elecraft] Interfacing K2 to KPA1500?

The KPA1500 Manual mentions using a K2 with serial interface for band data, but does not show how to wire it (that I can find).  I can't find it in the nabble archive either.  Does anyone know how to do this? Thanks and 73, Eric WD6DBM

Eric, The KPA100 RS-232 data appears on pins 2 and 3 of the AUX IO connector with pin 5 being RS-232 Signal Ground. Chassis ground is on pin 1. See the KPA100 manual. DO NOT connect to any other pins of the AUX IO connector, those are internal K2 signals to be used by external devices such

Use the Kenwood diagram in the KPA manual. Use the pinout in the K2 manual for the serial port and wire accordingly. 3 wires (TXD, RXD, GND) is all you need from the K2. Then select SERIAL as the radio type in the KPA. You may also need RADIO POLL to be turned on. Ken K6MR From: eric

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

A random-length wire is usually chosen to avoid a half-wavelength on the frequencies you’ll be using. A more accurate term is non-resonant end-fed antenna. Avoiding half-wavelengths means the impedance will not be 5000 Ω or greater, but it will be pretty high. Or low. The SWR on the feed line

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Mr. Mike, Be sure you have the KAT3 internal ATU "enabled" and not bypassed, be sure the proper antenna is selected (ANT 1 or ANT 2) for your random wire, and press (momentary) the ATU TUNE button. The relays will clatter a bit, and you'll see the displayed SWR ratcheting down, maybe up for

A matched conditon does NOT prevent the components of the tuner from seeing high voltages and/or high currents.  Check out TLW ... the transmission line application that comes free with the ARRL Antenna Book.  Pick a load that gives a high SWR and then click on the "Tuner" button for the

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Hi Mike, Its not wise to use the K3 antenna tuner to tune a random wire. A truly random wire can easily produce VSWR greater than 10:1 which is likely to damage the K3 tuner when running at full K3 output power. Its much wiser to use an external tuner with a random wire 73 Frank

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Very occasionally the K3 ATU will not find a good match and you may be able to do better by setting the tuning elements yourself. That is the case for my 70' endfed wire on 160m. The ATU will match it on all other bands though. To tune the elements manually select "LC Set" in the Config:KAT3

Re: [Elecraft] No longer shows SWR/RF, Keyer/Mic does not help

Actually you can be in "Data A" or "AFSK" but not in the internally generated data modes. Data A is basically USB with no audio processing and AFSK is the same but LSB. So check your data mode if you are in data. ALC is not needed for the other 2 settings because they are generated internally to

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Tuning happens at low power, so transients are small. After it is matched, why would the K3 ATU not be rated for full power over the full SWR range? Other components might fail, of course. Amphenol UHF connectors are only rated for 500 V. wunder K6WRU Walter Underwood CM87wj

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Hi Mike, You do have an alternative: Rather than using a random wire length, chose a wire length that produces well under 10:1 VSWR on the frequencies you intend to use. For end fed random wires, avoiding wire lengths close to multiples of 1/2 wavelength should be safe with the K3

The comments are good . But considering all the pluses and minuses, wouldn’t it make more sense to use a OCFD and not worry about ground rods, counterpoise needs, high SWR, high voltage and currents in the tuner? A well designed OCFD with correct Balun plus a common mode choke at the feed

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

Seriously??  Why do you think that Elecraft's tuners (like just about every other one) have max power ratings that differ depending upon the SWR?  For example, for the KAT500 has a max power rating of 1000 watts into a 3:1 SWR but only a 600 watt rating into a 10:1 SWR???  It can match both
