[Elecraft] A question about low sensitivity

Hi guys, Been a while since I last kept up with the list. You were a great source of help back when I built K2 #1133. Now I have #5226 and have completed the second section of construction. The receiver works, I can hear stations on 40. Yesterday I listed to Mid-Cars, Southcars, and

RE: [Elecraft] A question about low sensitivity

It is difficult to suggest just where the problem may be. It could simply be a matter of filter alignment, or it could be something not right in the receiver path. Since the receive path is now complete (although the front end is now built only for 40 meters). so you can either debug it now or

Re: [Elecraft] A question about low sensitivity

Joe: I suggest that you check the installation of C6 the 4.7 pf disc located on the very back of the board between L1 and L2. This capacitor shouold be installed so that there is an empty hole between the two leads. You actually install it in a spot for a jack that is installed if you

Re: [Elecraft] A question about low sensitivity

Hi Double check T7. Make sure the green winding is in 1 and 2 and the red winding is in 3 and 4 closest to the IC U12. If it is backwards the sensitivity will be low, the audio will be low and the AGC will not work properly although everything else will appear OK. Don Brown KD5NDB -

[Elecraft] Lead Free SMD Components?

I was shopping Mouser for components for a project. I noticed the SMD devices I need are Lead Free. Will I have any trouble soldering these components with Tin/Lead solder? Mark Saunders, KJ7BS Glendale, AZ ___ Elecraft mailing list Post to:

Does anyone have a link to a photo of a K1 with the KBT-1 internal battery installed with the K1's cover in place? I cannot find any photo's of what the two knobs look like to access the battery compartment. Thanks! Tom K2TA ___ Elecraft mailing

Re: [Elecraft] K1 with internal battery

Thanks Mike and Paul! I was looking at the photo on the Elecraft website and saw there where still provision for four 3D screws to hold the cover on and imagined a smaller cover directly over the batteries that had two knurled screws holding it in place. The verbal description of the two knobs

Re: [Elecraft] A question about low sensitivity

Hi Don, You nailed it I put T-7 in backwards. Duh!. As soon as I put it in correctly, well it sounds like a K-2 ought to. The K-2 was a Christmas gift from my XYL and I am enjoying the build. With this problem solved Phase II of construction is complete. I must call the House of

[Elecraft] TL05 vs LM385

I need to replace U6 in my KPA-100 and have a TL05 from Radio Shack. It's a dual op-amp with the same pinouts as the LM385 but not sure if they are interchangable. Any thoughts? Tom K2TA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net

Re: [Elecraft] K1 with internal battery

The KBT1 should have been made easily removable so that the compromises associated with having it installed need only be suffered when absolutely needed. The KBT1 *should* attach via a cable with a polarized two-pin female connector to a male connector *anchored* on the RF board. This

Re: [Elecraft] K1 with internal battery

WOW! Great job Steph! I happen to have a 3-pin socket handy here. I think add the diode to the RF board and follow your example on the stock K2 cover too. Plus the 9-volt snap connector is fast. Also allows 1 or 2 quick contacts with a 9 volt transistor radio battery in a real emergency.

Re: [Elecraft] K1 with internal battery

I originally ordered my K1 with the internal battery accessory. Didn't like the little speaker at all compared to the larger one. Also the cells were a pain in the butt to install and remove for charging. I never thought about leakage, but that makes a lot of sense! I use a 10 cell holder with

[Elecraft] KIO2 Questions

I have recently finished the KIO2 accessory for my K2. Everything appears to checkout as it should but I have a strange behavior using the KIO2 and Ham Radio Deluxe. My control board is Rev. B and as I understand from the manual there should be no modifications required of the board itself?

RE: [Elecraft] KIO2 Questions

Ed, While I may be wrong, I would think there is no problem with either the KIO2 or the K2. If you look at the KIO2 Programmers Reference, you will find that the K2/KIO2 report (or get) the frequency in 11 digits - the high order and the low order digits are ignored when sending a frequency to
