Hi Paul, Presume you meant 2450mAhr AA size. 2450Ahr is something quite huge that unless the very latest high capacity (and expensive) block NiMh cells are used, would entail you using a trailer to haul them about. We had 3750Ahr 2V lead acid batteries cells in the workplace com site's solar powered battery plant and they were big! The 2450mAhr AA version is as you say very usable in digital cameras, but you do need to keep them charged up as they seem to gradually go flat if left in the camera for a long period of time. Another downside is the increase in capacity had brought on a very definitely noticeable rise in weight.

At 9.6 volts I am not sure what power output I will have... If it doesn't work out for the K1 I can always use them in my dig. camera! My 2c worth: Modern high capacity NiMH batteries (I have about 30 of them, up to 2500mAh AA size, for camera, CD player, GPS, etc...) seem to have to following characteristics: * Fully charged voltage of about 1.35V * After initial current drain, this drops to about 1.25V and stays there until about 90% drain. * They lose about 10% of their charge per week on the shelf. * They ideally need an intelligent microprocessor controlled charger for best results. * The largest capacity AA ones are quite a tight fit into AA holders. In my experience, rechargeable NiMH AA batteries are better than Alkaline cells despite their lower initial operating voltage. Alkaline cells drop their voltage more rapidly in the second half of their discharge cycle and tend to give lower power overall. I tend to make up a battery with an extra cell to offset the voltage difference. Lithium cells have a higher capacity and hold their voltage well throughout the discharge cycle but are a bit more expensive. Li-Ion/Li-Polymer rechargeable cells are not, as far as I am aware, available in AA size commercially (yet) and also have other problems. They need a special dedicated charger and cell life is limited to 18 months to 2 years regardless of use due to cell degradation.

[Elecraft] KFL1-2 parts question
Since yesterday was a holiday, I was going to take it easy and build my KFL1-2 option for my K1 instead of working hard at being retired but I was missing a part and I have a question about another part. The PIC chip on my KFL1-4 board has a paper tag stuck to it that states KFL1-4 and the version # but the tag on the KFL1-2's PIC chip states K1 I\O which sounds suspiciously like a wrong part. Could any of you take a peek at your KFL1-2 and let me know what its tag says? -- John [K7SVV] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] KFL1-2 parts question
I don't have a KFL1-2 for my K1, but the chip in both is called an I/O Controller on the schematic so my guess is that it is the correct part. There aren't any other K1 I/O chips as there aren't any other K1 I/O options!

Is there a way to mute the speaker output of the K2... perhaps in some of the menus?

I took the side panel off and the speaker ohms out correctly at the connector end. Is there a way to mute it that I might have enabled? John -- No virus found in this outgoing message.

You can become accoustomed to either but I prefer the narrow range. The knob is much more sensitive on the wide range.

RE: [Elecraft] K1-4, Which VFO range selection, 80 kHz or 150 kHz
I tried 150 khz at first. The tuning is WAY too fast and the added frequencies are of no use to QRP for the most part. I changed to 80 khz and the tuning is slower while providing coverage of the most active CW portions of each band. I also built for 10.1 mhz as most of the useful QRP activity seems to be 10.100-10.120.

The tuning is WAY too fast and the added frequencies are of no use to QRP... I've been using K1 #175 in the USA since November 2000, and I find the advantages of the 150 kHz span to be overwhelming, but **only** for use in this ITU region. IMHO, the 150 kHz span (actually it's about 170 kHz) has a very controllable and acceptable tuning rate (after FP-R19 was added to the design in 2001 to linearize the tuning rate at about 17 kHz per turn). I also use a little felt padding placed between the VFO knob and the front panel to give a slight amount of rotational resistance. No matter which span is used, the VFO potentiometer shaft needs this extra resistance, IMHO. and the added frequencies are of no use to QRP... No use??? Certainly there is some use in this ITU region, where 7100 to 7150 kHz is excellent QRP territory and the main justification by far for choosing the wide span. Cross-mode (Morse-LSB) contacts in the phone band from 7150 to 7170 MHz are possible, since the K1 receiver operates in LSB mode (on all bands). When 15m is hot and one or more of the 6,666,666 different contests is wasting good RF energy, 21100 to 21170 kHz provides a haven for Morse QSOs. I also built for 10.1 mhz as most of the useful QRP activity seems to be 10.100-10.120. With the 170 kHz span and the 1 kHz band edge crystal installed, time and propagation info are often available from WWV at 10 MHz in the USA. A useful capbility. HOWEVER, if I lived in another ITU region where Morse operation from 7100 to 7150 kHz was not allowed, and where WWV could not normally be copied, I'd choose with the 80 kHz span. That is probably the best setup for your European K1. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
