Re: [Elecraft] K1
I am worried about the torroids should I be? Yes. As folks have mentioned, winding toroids is not scary. Count carefully and correctly -- the directions are clear -- and you're all set. What I'd worry about is tinning the leads well and sufficiently close to the core so you don't pull enameled wire through the PC board hole when soldering in place. Poorly tinned toroid leads (PTTL) are a common problem. Take care and you'll be fine. Good luck with your K1. It is a great rig.

Re: [Elecraft] FS: KFL1-2
Price reduced. Now $55. Scott For sale: KFL1-2 + K1B30 K1 2-band filter board for 80 and 20 meters, plus 30m parts. K1 #139 started out as a 30/20 transceiver, but became 40/30/20/15 when the KFL1-4 came out. I replaced 30m with 80m on the old board, but lack an 80m antenna so never used it. The filter board and spare parts have been in a drawer for years and I've decided not to store them any longer. Give your K1 2 new bands. Several of these boards are on 160m (see archive). New, unbuilt price from Elecraft = $65 + $7.50 + shipping =~$75 I'll sell postpaid to a US address for $65.

[Elecraft] Comparing SLAs
I used a 5Ah Powersonic PS-1250 gel cell to power my K1 for a few years before it faded. In shopping for a replacement, I find they're about $25, while another battery with the same dimensions and capacity made by Rhino sells for $8. I'm assuming the Powersonic is a better battery, but I don't mind a small reduction in performance if I can get 3 batteries for the price of 1. Is this a smart savings?

Re: [Elecraft] {K1 2277] VFO Alignment--VFO Range selection, 40m, 20m.
Rich, Both 80 and 150 kHz have their adherents. 80 kHz will give you tuning that's less touchy, though I've never had trouble with 150 kHz, even without the felt mod. The wider band will let you hear WWV on 10 MHz and get you into some less crowded frequencies -- especially helpful when there's a big contest on, for example. You can't go wrong either way, I don't think. You might search the archives for K1 tuning range for more opinions. AFAIK, CW is the only digital mode supported by the K1. Good luck.

Re: [Elecraft] [K1-2277} Front Panel construction -- R1
If your VFO tunes in a direction opposite what it should, then you have something reversed with the pot wiring - no other harm will come of it. Also, a certain miswiring of the K1 tuning pot will leave you with virtually *no* tuning range. Yep, I've done it.

Re: [Elecraft] Can't search the email archives successfully, looking for K1 VFO
Mike, RF-C2/C2A is the capacitor choice for selecting K1 VFO range. My K1 manual addresses this on pages 12 and 38. You may need to change a crystal for 30 m, too.

[Elecraft] K1 VFO trouble
My K1 VFO has stopped tuning. The rig was (pretty much) fine till I replaced the tuning pot (plastic for metal), but the problem doesn't seem to be there. I measure approx 0 to 100 k resistance as far as pin 1 of RF-RP2, so the new pot appears to be doing its job. Voltage measured at D3 (5.9V) changes less than 0.1 V thru the entire 100k tuning range, however, which I don't think is right. Other info: RIT works. VFO OSC = 3.086. I can hear WWV at 10 MHz. E42 occurs with pot at 100k. Can anyone tell me if this points to a particular culprit? I'm continuing troubleshooting, but time at the bench is at a premium and I'm hoping to find a shortcut to the solution.

Re: [Elecraft] Adding 80 and 17 Meters KFL1-2 to K1
Greg, Do you have the F-5 errata sheet? Step 4 gives some guidance. http://www.elecraft.com/manual/E740016E_K1_Rev_F-5.pdf Scott N1AIA All going well until on the 80 meter band kit it mentions about adding the 10-uF electrolytic capacitor at C78 on the bottom side of the RF board. I can not located C78 anywhere on the board. In checking the parts list for the RF board I find the capacitor count only goes up the C75. I have the K1 RF Rev. D board.

[Elecraft] K1 VFO reality check
After years of putting up with a touchy K1 tuning pot, I finally put in a metal-shaft replacement. The new one felt great, but was tuning backwards (duh) so I switched the leads, put the cabinet together, and now the VFO doesn't tune at all. The LCD indicates I'm at the bottom end of the band when I turn the pot just above the stop. Right at the stop, I get an E42. (I was getting that E42 at the stop *before* switching the leads, too, which felt wrong, but I was able to change frequency anyway. Looking at my notes later, I realized I had had a tuning range of just 60 khz, even though I've been set up for the greater tuning range (150 khz plus).) I've poked around a bit. Pin 14 on P1 on the RF board measures 0 to 100 k ohms from one end of the pot to the other, so I am assuming the trouble is not on the front panel even though that's the only thing I was tinkering with. This is my reality check: Does that resistance range at the board junction eliminate the front panel as the problem area? OSC shows me in the right range, RIT still works, D3 is at 6V, D4 is at 3V, and I'm looking for hints about what might be going on.

Re: [Elecraft] Wha'ts Wrong With Our Radios
On the rarity of XIT necessity... The need for XIT is much greater in a rig without the split option. On the K1, switching between XIT and RIT helps me track other callers when DX is listening up (even though the range isn't that great). For me, split operation is one of the chief lures of the K2.

[Elecraft] Uses for K1 MCU?
Long ago I upgraded my K1 from firmware version 1.06 to 1.09. I kept the old MCU, a PIC16C77-04/P, but I'm not sure why. If I'm not a programmer, would I have any use for it beyond reverting to 1.06 in an emergency? What have other K1 upgraders do with theirs?

Re: [Elecraft] K1 enthusiast wonders ??
Mike noted (among other things): the K1 Quick Reference Card ... still has several errors that were pointed out more than two years ago. I also ran into a critical area where K1 web info was well behind the times (though the reference was updated when I pointed it out). I took this (correctly or not) as an indication of Elecraft inattention to continued refinement and development of the K1. I'd like to be wrong, but I think the K1 heydey is past. That's understandable, because Elecraft is busy with other interesting and exciting work revolving around the bread-and-butter rig... and maybe busy with some fascinating new projects. The mod world is pretty quiet, too. The K1 zenith appears to have passed. This reflector is just reflecting K1 senescence. (Again, I'd like to be wrong.) Incidentally, I also consider the 4-band board and antenna tuner to be essential K1 accessories. Because I have them, I wrongly assume that everyone has upgraded. At this stage, I would be much less enthusiastic about a 2-band K1 sans tuner. I don't think that such a standard can compete with the KX1.

Re: [Elecraft] K1 enthusiast wonders ??
K1KID wrote It seems the K1 has fallen off the radar screen here My only HF rig is the K1 and it suits my needs well. I'm lucky if I get a half hour a week for hamming and I'd prefer to spend that time on the air, not in the rig. But eventually something will need fixing or adjusting -- the output seems low; the frequency jumps 30 khz when the knob gets bumped; the RIT mod still isn't working right -- and opening the K1 doesn't seem so overwhelming. As much as I would love a K2 and a KX1, their complexity intimidates me. Maybe it's just perception: That's something I won't know till I find more money and time. My K1 cost me half what the K2 would have when built to suit, and the KX1 wasn't available when I bought the rig. If I was shopping today, the K1's price and 7-band capability would steer my decision straight to it. I use a padded lunch bag or an amazingly well suited cardboard shipping box for transport. My 7Ah gel is great for home operation, but I'd rather have something slimmer for the days I'm portable. Sometimes I take a pack of 8 AA alkalines. I'm not sold on the KBT1. I desire solar.
