[Elecraft] K3 and IC- 2KL; negative voltage modification

Guys, Does anybody here use the K3 with the IC-2kl amp? Is the negative ALC modifcation really necessary? 73, Chris-OE5CSP -- View this message in context: http://n2.nabble.com/K3-and-IC--2KL--negative-voltage-modification-tp1617415p1617415.html Sent from the Elecraft mailing list archive at

[K3] RE: [Elecraft] K3 power tripping out

Adam, I don't have the KDVR3 fitted. I suspect it's because I'm running too much output power causing the K3 current sensors to trip. I'm going to try reducing my output power a little and see if that cures it. 73 de Paul G4AFU Original Message From: [EMAIL PROTECTED] Date:

I use the K3 with a 2KL. I have the parts for auto band switching (decade band info convertor) but have yet to build it. The max power setting I use is 25 watts for 500 watts out but have to watch the K3 power closely. The 2KL trips out easily when over driven and depending on band, mode and

RE: [Elecraft] K3 Band Data

The BCD encoding is the same as the FT-1000D/FT-2000. Interfacing to a microHAM or TopTen Band Decoder requires no internal modification (both products include pull-up resistors on their BCD inputs). The Elecraft KRC-2 and W9XT Band Decoders do not have pull-up resistors and will require

RE: [Elecraft] K3 Band Data

The Elecraft KRC-2 and W9XT Band Decoders do not have pull-up resistors and will require the addition of 2.2 - 10K resistors Not true of the KRC2 IF you are using the AuxBus line. I have the K3 ACCY AuxBus connected to the KRC2 and it works great. No changes needed.

RE: [Elecraft] K3 Band Data

Not true of the KRC2 IF you are using the AuxBus line. The question was specifically with respect to BCD output - not Aux Bus. Neither the microHAM Band Decoder not Station Master require any modification (or care about the BCD coding) if the serial (CAT) data is used for band decoding

If you intend to run FSK you need to make an interface (see the AA5AU website) to connect a com port to pins 1 and 5 on the K3 ACCY connector. If you are going to run AFSK you can use the K3's serial RS232 port and set either the RTS or DTR lines for PTT and connect the K3 Line in/out to

Re: [Elecraft] Scan Rate Adjustment

Heh, that's funny, I just requested the same thing... However, you can get several scan rates by using FINE, COARSE or RATE. These give you aprox 150 Hz/sec, 1.5 KHz/sec and several kHz/sec, if I recall. I wouldn't mind having an intermediate rate between the two slowest ones. One seems too

Re: [Elecraft] NG0R - K2 Build/Alignment Issue

John, It is difficult to say because the 2 transistors are tightly coupled. One thing I can say is that the emitter voltage is suspect. Both emitters are tied to the ground plane and should be at the same RF potential. OTOH, the difference between 24mv and 0.4mv could be expained away
