K2 Digital Signals Mod
Locked
 
|
Greetings All,
I'm about to install my KSB2 and was looking at the modification listed on the website that brings out the microphone jumpers and signals necessary for digital modes via a ribbon cable and small PC board. I've monitored this list for a while and have not seen much posted regarding the mod. Have many done this? Is the PCB available somewhere? (I was considering "deadbug style" construction) Thanks & 73 de Mike, N0SO K2 #4757 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

It would be nice to have it all in one box, but this way I can switch rigs very quickly. I also use an external speaker so I can monitor the received signals easily with the laptop soundcard connected.

Hi Pete,
I too am using my K2 and a RigBlaster for psk31. I am only running between and 5 and 10 watts, or so out on 20 meters and haven't been having much luck making contacts. Previously I had used a Yaesu rig putting about 40 eatts into the same antenna and had no trouble at all making contacts. I have almost completed a 35 watt amplifier (HFPacker amp, I think its called) so I can get a bit more ooomph. I was wondering if you or anyone else is using the K2 barefoot and if so how you were doing with psk31?

For a while I was using my K2 barefoot with a Rigblaster to run PSK31 on 10m for the PropNet PSK project. It was last summer when I was doing so and I noted several openings. I made a couple of local and a few other PSK31 QSOs with it on other bands prior to getting it hooked up for PropNetPSK.
I hated to use the K2 for a dedicated project so I've since taken it offline and have been using it otherwise on lots of bands, mostly CW, but some SSB, all QRP and quite effectively. I tried using an HTX10 for a dedicated PropNetPSK rig, but the frequency stability and sensitivity leave a lot to be desired compared to the K2!

Hi I have a bare foot K2 that I only use for digi modes (Normally PSK)
I run about 10 Watts Max on peaks. I don’t seem to have many problems getting qso's at this power level, I just a have a 1/2 size windom up at about 25ft here . Never really needed more power than that, make sue your signal is not over driven and nice and clean to make sure its readable at the other end.

Mike,
Pauli unfortunately is a silent key, but you want to consider an alternative, take a look at my webpage (http://w3fpr.qrpradio.com article on A Fixed Audio Output for the K2. If you take the audio out to a spare pin on the mic connector (pin 5 for the Elecraft configuration - remove the mic header jumper for the pin used), then all signals needed for an external digital modes box are present at the mic jack - audio out, mic AF in, and PTT. I might add that Pauli himself surprised me by ordering one of these boards claiming that it was an easier and more simple solution than his interface implementation. I recently mounted one of the Fixed Audio boards in a K2/100 - I laid the capacitors and the resistor down flat on the board and attached the wires to the board with no connectors, and the audio out plugs onto the mic configuration header. It fits nicely in the space between the control board and the front panel - and there is even a hole in the control board near the left mounting screw that can be used to attach the board. I will eventually update my webpage with this additional info, but I'm too busy right at the moment. I do have boards available at $3 per board plus $0.50 for 1st class mailing US domestically - $2 air mailed internationally), but no more kits - if you are interested in a board and documentation, email me direct (without '[Elecraft]' in the subject line), and I will supply my address (or look on QRZ.com). 73, Don W3FPR > -----Original Message----- > > I'm about to install my KSB2 and was looking at the modification > listed on the website that brings out the microphone jumpers and > signals necessary for digital modes via a ribbon cable and small > PC board.

Thanks to all who responded to this. I've decided not to do the mod right
now and connect via the existing mic and headphone or speaker jacks. 73 de Mike, N0SO K2 #4757 -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Mike Heitmann Sent: Friday, February 03, 2006 8:12 AM To: elecraft: mailman.qth.net Subject: [Elecraft] K2 Digital Signals Mod Greetings All, I'm about to install my KSB2 and was looking at the modification listed on the website that brings out the microphone jumpers and signals necessary for digital modes via a ribbon cable and small PC board.... _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Well, I run my K2 at 5 watts on PSK31, and make a contact or two everytime
I get on. Its not as easy as it use to be and I end up calling CQ alot. Only a few times have I not made contacts. The bands are not as good as they were, and all contacts I have to work at. My problem is once I make contact is keeping it. Usually can make it thru 1 or 2 rounds then loose it. I've got a HF Packer amp about 3/4 built, but honestly have not seen the need for it. Someday when the bands get really bad I'll get off my tail and finish it. The antennas are nothing fancy a 22ft vertical with 14 radials, and a G5RV up 18 ft. Now this is a little off subject I run 5 watts mobile cw 2-3 times a week and always make a contact. Don't know what else to say, just stick with it.
