Roughly how long does the cell last? My K3 is >5 years old! Mel, K6KBE

If you take the top cover off with the front of the radio facing you. It is to the left. I think it is a CR2032 button cell.

Mike….. the Only Button I know about is the Door Bell Button ! 😊 I would replace the 33Pf cap with a 22Pf. I used to use K3EZ software to make adjustment to my K3, But it wont Down load

The Cap is C60, near Xtal Y1 and IC U16. They are on the Back Side of the Front Panel Board. C60 is a 33 Pf Chip Cap. Y1 is a 32 Khz Clock Crystal, silver in color. U16 is a PCF8563T IC, 8

Easy enough to write a script to set the clock via computer. Or use Win4k3Suite or any other software package that does this (HRD maybe?) Now... if you're not bringing a computer out in the field,

Please share with us which cap should be replaced with a variable cap. 73, István HA4ZD -- "az agyat ne terheljük fölöslegesen adatokkal, arra a könyvek valók, az agyat

Ray, Thanks!! I is kinda what I expected; the design guys did not go the extra $20 to install a variable cap. BTW, where is the button cell battery?? Mike W8TRN Sent from Mail for Windows 10

Kelly, forgot to ask: where is the button cell batttery? Mike W8TRN Sent from Mail for Windows 10

Kelly, Thanks for the reply. Yes that is a bunch of time but the K3 has been doing it since day one. And I agree, they cut a corner by not going the extra $20 to sync it to a standard.

That does seem a bit large for a delta over 3 days. But you have to remember that the reason a computer keeps such good time is that it is constantly syncing up with time servers. Your (and my) K3

The Clock runs on its own Crystal Osc. The ‘Time Adj Cap’ installed is a Fixed value and can Not be adjusted is Built. You would have to Remove the Chip Cap and install a Variable Cap to make it

Possible the button cell battery is weak? Otherwise I know the win4ksuite has an option to set the time to the computer time each time it's launched.

I have had a K3 for over a year. The #1 complaint albeit trivial is the clock/time display : if I set it spot on today, within 72 hours it is about 3 minutes slow. I must reset it just about every 3 -

The data did not show as expected in my last post. Try again. K4SV CW s/n 1886K4SV CW s/n 1886K4SV CW s/n 1886Drake model 1551 Dummy Load neasured through the HM-102 power meterBANDHEATH

Still have problem listed above. Following is more data that may provide some clues. I did not adjust the two capacitors as suggested (yet) because the gear belongs to someone else. The data answers

I had a similar problem with AF knob on my K3 and it was a split knob that did not tighten down on shaft, so remove knob and turn shaft if problem is gone possible knob if it persists it may be a bad

Jeff, you can use the dummy load create a mis-match by inserting an air wound induction in series with the DL. Just measure with ant analyzer so you get about 2.5 - 3:1 mismatch at desired freq, now

Jeff……… If you want reliable Date From the Test you do, Then use a Calibrated Load. This is How it is done in the Broadcast World. Wa6vab retired.

I'm not sure what using a dummy load as the load would really prove? We already know that when the SWR is fairly good (i.e below a 2:1 SWR) there aren't any issues and the ATU works just fine. The

I had the same issue... Sent to factory, took three weeks, and works now... I had them replace all 4 while they were in there. 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer
