[Elecraft] Y adapter for FT-817 / T1

Does anyone make and sell a Y adapter for the FT-817 that allows a CAT cable and the T1 adapter to be used together? I probably have the bits to make one, if I had a diagram for it, but as my eyesight is no longer up to doing construction I'd rather buy one ready made if possible. 73 de

Hi Dave, I noted your 10 Nov. discussion as to filter widths. Are you nstill in possesion of my old K2 S/N 02763 ? Is this the one you have modified with the 2.6 Kc. width ? Just curious. 73, Bob VE3XM K2/100 S/N 04031 K2 S/N 04575 ___ Elecraft

[Elecraft] KPA100 rev D

Hi Wayne, There a reason for concern for eliminating the choke in the antenna circuit. I noticed that there is no DC path to ground to eliminate the chance of static potenital build up on an antenna from discharging a high voltage into the rig. This may be the reason why some builders have

Don, Just to clarify - does this include the mod to L1 on the KIO2 AUXBUS board as explained on the KK7P web site? I found a contradiction to this mod on KI6WX site. (Was or is there a possible current draw problem through L1)? Thanks in advance, Dave, W8FGU -Original Message- From:

RE: [Elecraft] kpa100 with kat100-2

Hey Lyle, I didn't think it would hurt to replace L1 - just thought maybe the problem went away with my version (rev C) of the KPA100. BTW - very nice explanation of separating the K2/KPA100 - I ordered the parts yesterday to split mine. Thanks for the nicely detailed process. Dave, W8FGU

Dave, There isn't a contradiction between what Lyle and John describe. Lyle was taking a conservative approach to the issue. Nothing wrong with that. John did some extensive tests and found it wasn't necessary. Both approaches are equally correct. Being lazy, and after reading John's test

RE: [Elecraft] kpa100 with kat100-2

Joe, I guess contradiction was a little strong ;-) I just wasn't sure if the later revs of the KPA100 eliminated the issue entirely. I'm somewhat lazy as well and adhere to the KISS principal (most days) so I was leaning with not replacing it. But then again, I'm pretty conservative with regard

[Elecraft] Free: K2 QRP top cover sheet metal

I was going through some stuff and ran across a brand new K2 QRP top cover. I built my second K2 with the KPA100 immediately, so I never built up the QRP top. This is the sheet metal only, no parts attached. If anyone could use this, send me your address and I'll send it to you. Ken K6MR

[Elecraft] CW station calling an RTTY station: use mark or space frequency?

Hi all, Suppose you were an RTTY station (FSK, narrow shift, in the HF bands), and you were called by a CW station. Assuming that this didn't annoy you too much, would you rather the CW station be on your mark or space frequency? I've made one cross-mode QSO this way, so far, and I want to

Re: [Elecraft] CW station calling an RTTY station: use mark or space frequency?

I'm going from memory dating back many years, but I think RTTY stations normally ID in cw by sending cw with the key down on the space frequency, and key up on mark. Sticking with that convention might make it a little easier to copy for them due to familiarity of the tones. I'm not sure too

RE: [Elecraft] CW station calling an RTTY station: use mark or spacefrequency?

And I thought I was the only one crazy enough to use my KX-1 to listen to RTTY and PSK-31 ... I never thought of calling them on cw..but I don't have enough RTTY experience to know which tone is better. Ken K6MR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL

I hardly dare to confess and I die of shame ( sorry Frank ). The 20 dB difference I noticed in ( audio ) S/N figure does ( of course :-) not really exist. Guess what ? I forgot to switch off the .nt in de ssb mode. I stand corrected ! Lesson learnt. The SSB ( w.o. DSP ) mode has ( in the same

[Elecraft] K2 and RX Beverage antenna

Gary, I have the RX antenna on both of my K2s. I actually share the beverage antenna between the 2 rigs. If I have both RX antennas turned on, I lose about 3db on each, but that is no big deal since the signal is way down anyway and you are simply looking for better signal to noise ration with

Re: [Elecraft] K2 and RX Beverage antenna

A word of caution ... I severely damaged the RX antenna RF stage of my FT-1000D due to RF coupling from the TX antenna (1KW, 160M) into the RX antenna. I later measured the induced RF voltage with a 'scope ... it was many volts. Some commercial (marine) receivers have lamps in series with the

Re: [Elecraft] CW station calling an RTTY station: use mark or space frequency?

Wayne, MultiPSK is testing a Reed-Solomon based mode identifier using a key-codeword and parallel decoding. When the program is in auto mode, it will detect and automatically switch modes.Then you would just have to send a special CW character sequence and the receiving program would switch
