[Elecraft] K2 L25 and L26
Hello. I am building K2 SN3278 and am about to install L25 and L26 (40m low pass filter). I have pre-wound toroids BUT the pre-wound toroids both have 16 turns. The manual says L25 should be 14 turns and L26 should be 12 turns. I assume that the manual is correct but wanted to double check.

On 9-Aug-04, at 4:17 PM, Tom Whiteside wrote: their may be filter considerations to achieve PACTOR III speeds. Hi Tom I have successfully used my SCS PTC IIex modem with my K2 for Winlink remote email application. I interface it to the rig through the mic jack with the mod to bring receive audio to the mic jack through an unused pin. I am thinking of adding a din receptacle to the back of the rig to make the connection direct and leave the mic jack free. I run Pactor III with no trouble whatsoever and achieve great data throughput. The K2 (QRP) with the SCS modem is a dynamite combination for keeping in touch via Winlink while traveling by boat, rv or even at the picnic table up at the cottage. I can make connection with the host stations on 40 and 20 with a 22 foot wire thrown into a tree and a counterpoise. 73 Rick, ve3mm K2/100 #1591 KX1 #188 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Elecraft parts
Folks, I too agree - Ordering parts from Elecraft is not only easy, but you do receive personalized service too - Scott and Richard do a fantastic job, part numbers help a lot to avoid ambiguities, but they are available and receptive with information about a particular part should the part number not be readily available, one will not find that level of service at Mouser. Now, I do order often from Mouser (and Digi-Key too) and they also are really fine folks to deal with. If I am ordering in quantity for my parts stock or for a non-Elecraft project, they will be my primary choices, but if I need a particular part for a K1, K2 or KX1 (or any of the options), I pick up the phone and talk to the fine folks at Elecraft - it arrives in the mail within a week (OK, this is location sensitive, and parts from Mouser or DigiKey arrive in 3 business days for me, but the shipping cost is more than from Elecraft). 73, Don W3FPR - Original Message - I cannot fault your logic ONE BIT!

Just a thought... My only(!) problem with Mouser is that they now ship EVERYTHING in a box which costs no less than $6.50 to ship (UPS). They used to ship small parts on padded envelopes for a couple bucks, but now nothing goes out unless it's boxed. I do, however, like the fact that no matter how small your order, there's never a handling fee and only ACTUAL shipping is charged. There IS a $1 'handling' charge if you ask them to ship via USPS because someone must hand-carry the box (again) to the P.O.

[Elecraft] directional diodes 1N5711
First, thank you to those who responded and taught me the difference between these several types of diodes. Now, to share an experience, actually, several. three times in five years have had my radio go awry on transmit, and all three times the cause was the same; directional diodes in the SWR bridge. Specifics of the symptom vary because, for example, this time in the K2, the FWD diode fried infinitely open in both directions, while the REF diode fried shorted. In the KPA both diodes fried leaving 1.5K in both directions. Specific details of radio behavior were quite different, but general behavior, loss of the power control on the K2, HI CURR report from the radio trying to run all out (since the bridge is reporting inaccurately what power is going by it), unable to use the auto-tuner, inaccurate SWR and power out reporting. KAT-2 ... not a recommendation, just a comment. I mount the diodes on the underside of the circuit board. This puts them on the outside of the KAT-2 module which makes it possible to replace them without any disassembly. KPA ... I haven't yet thought of anything clever for making these diodes more accessible, would be nice. Kirby, who really does know, suggests putting a 1 uh choke at the input of the directional coupler to protect these diodes. Once that is done, however, one will no longer be able to check the viability of the diodes while in the circuit since this will look like a short to ground to a DVM. I am sure this problem occurs more or less frequently depending upon where one is located, and what kind of antenna. For example, I have never lost these diodes when using my forty meter full wave loop which puts the antenna at ground potential. Lost them now after putting up a G5RV flat top which seems to have no trouble gathering static even in a clear sky. The KPA has a 100 uh choke across the antenna jack. That did not protect the diodes in the KPA, dunno why. I am sure it protects the finals. P.S. Had a friend lose K2 finals to ESD. Is there any reason why one couldn't put that 100 uh choke across the antenna jack on the K2 f???

[Elecraft] K2 Firmware change request
I used my pair of K2/100's in last weekend's NAQP CW. Band conditions were pretty good for August, and I ended up with 789 qso's. I use the pair SO2R, meaning I am listening on one band while transmitting simultaneously on another band. In the NAQP mults count on every band (including 160), and you change bands a lot. I was reminded again of a K2 firmware bug that has been very annoying to me: after changing bands, the K2 transmit power is reset to zero. I takes several dits for the power to come up to 100%. That means if I change bands, the first station I call gets something like AOGW instead of N4OGW! If I forgot to hit the tune button or send a string of random dits, the station I was calling frequently came back with ? I'd rather not have to QRM other stations tuning up every time I change bands. Is it possible to make the K2 start out at 100% TX power? Is this supposed to protect the finals? In the NA Sprint contest (coming up in September!) this is a really big deal. There, you must QSY after calling CQ, and if the station I am calling misses my call, I may never hear him again!

[Elecraft] carrying cases and ESD
My ESD problem with the K2 and KPA followed a severe shaking over washboard roads on a voyage to remote Chaco Canyon. The K2 was riding in a Lowes foam surround carrying case. I can not prove, but I do not think the ESD that zapped the directional couplers came from an antenna. It happened immediately upon reconnecting the K2 to the KPA (which had been left entirely disconnected and which worked perfectly before the trip). for me, at least, the moral of the story, I now have static free wrapping for the K2 when it rides in the foam fitting case. Maybe I am wrong, but can't hurt. Maybe this report will also protect others from the frustration. 73, Fred KT5X ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 Firmware change request
Might do. And then when you hit the key with the wrong antenna (or no antenna) attached, you may need to take a break and replace the finals. The K2 and K2/100 are very robust systems, but repeated abuse is sure to have its consequences. Even with manually-tuned vacuum tube gear, smart ops drastically reduced the power when retuning, especially on a new band. Circumventing this simple check in pursuit of an extra few seconds in a contest reminds me of the race driver who constantly winds the RPM up above the red line on the tach. He might get in the lead. He might even win a race or two, but he'll pay for it eventually. Maybe someone will find a clever fix to allow instant band changes without the added second to allow the K2 to check the output SWR and reset the power level. If so, more power to them, but I sure don't want to pay for it in the basic cost of my rig. Ron AC7AC -Original Message- Saving the setting band-to-band might work.

Problem solved. Thanks to Bob, Vic, Don and specially to Mychael for his perfectly wounds toroids. 40m Menu setting rAnt was ON. I changed it to OFF and 40m came to life again.

Re: [Elecraft] carrying cases and ESD
Hi, Indeed, vibration in mobile transport creates triboelectricity, a charge build up by friction of wires insulations against conductors. It could be not the foam of the box, (which usually is grey or black indicating carbon content) but the wiring inside the radio. It is always good practice to short a cable before connecting it to other electronics to remove any residual charge. 73, Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] SCS modems with a K2
Tom, The local SCS modem expert is Lewis Thompson, W5IFQ here at ARL. email him at the adr I will send, for info on the interfacing of the SCS. He has successfully interfaced them to the little 5 watt Yaesu radio, I know. I think it is pretty straightforward to interface the SCS to anything. The manuals are readable and VERY complete, as I studied one when he and I hooked the SCS to an Icom 756 Pro II. 73, Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] SCS modems with a K2
Appreciate it, Stuart - would still appreciate any feedback from a K2 owner who has tried this - the actual rig interface looks simple but they talk about supported rigs and transmit receive times and their may be filter considerations to achieve PACTOR III speeds.I did send Lewis a note on your suggestion - thanks!

[Elecraft] FS: K1 with lots of stuff
Hi, I am selling an Elecraft K1, s/n 918. It is in great condx, and it has the KNB1, KAT1, 4 band filter board (40,30,20,15 meters). Also included is the KTS1 tilt stand, KBT1 internal battery option (built but not installed). This radio has performed beautifully and has all the current ECOs in it. It also comes with a Pelican 1400 hard case (yellow), and is notched for the K1, dissaembled tilt stand storage, gell cell battery storage and accessories. This radio has just been sitting around and not being used, so I am sure there is a good QRP'r out there that wants to give it a good home. I will take $550 plus shipping (lower 48 states only) for all of the above. Please feel free to email me at: [EMAIL PROTECTED](replying on this email addy will get you there, anyway).

Re: [Elecraft] SCS modems with a K2
We used a PTCPro with a K2 on the T33C trip, and the radio and modem worked just fine for log uploads. I've also used my PTC-IIe with my K2/100 with the EA3BLQ mod to make a 6pin digital mode mini-Din attachment point. I wired it such that it matches the equivalent mini-DIN on the FT-817 and IC706MKIIG, so I can use the same cable for any of them. 73, doug ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
