K3 inside photo
Locked
 
|
Here's a photo I took of the inside of the K3 at Visalia. The tour that follows is from memory, sorry if I misremember. http://twistedoak.typepad.com/stuff/k3inside.jpg The front panel is at the top, and you can see four filters for the main RX behind it. I don't know what the two daughter boards are. Most of the main board components are on the bottom side. To the left where the toroids are, are the main RX bandpass filter for the amateur bands. My understanding is that the sub RX board fits on top of the main RX - but I didn't see that board. Center back is the heat sink for the 100W amp. Left back is the KAT3 tuner. enjoy! - jeff wk6i -- Jeff Stai [hidden email] Twisted Oak Winery http://www.twistedoak.com/ Winery Blog http://www.elbloggotorcido.com/ _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The two short standoffs to the left of the frequency reference are where the subreceiver synthesizer is installed. 73, Lyle KK7P BTW, the bright LED near the crystal filters tells me that either the RF gain was cranked back or there was a really stong signal being received :-) _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Not when you add the subreceiver, which has its own BPFs, I.F., and full set of roofing filters.... 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

K3 RX ant in/out

In reply to this post by wayne burdick
OK, my memory is a bit flaky sometimes.
IIRC, the RX ant in/out connectors can be used for an external front-end filter, or for a separate RX antenna system. What else can they be used for? 73, doug _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I'll bet you can order a full sett of K2 toroids that you can wind in
between assembly of the K3 :-) 73 de Tom LA1PHA ----- Original Message ----- From: "W2AGN" <[hidden email]> To: "Jeff Stai" <[hidden email]> Cc: "Elecraft" <[hidden email]> Sent: Tuesday, May 01, 2007 7:35 PM Subject: Re: [Elecraft] K3 inside photo > Jeff Stai wrote: >> >> Here's a photo I took of the inside of the K3 at Visalia.

OTOH,
It would cost more but for the nostalgic (or otherwise twisted) builders out there Eric and Wayne could offer a version of the K3 kit where you get to wind the toroids yourself...;-) Rob KC6ROC "Tom Arntzen" <[hidden email]> wrote: >I'll bet you can order a full sett of K2 toroids that you can wind in >between assembly of the K3 :-) > >73 de Tom LA1PHA > >----- Original Message ----- >From: "W2AGN" <[hidden email]> >To: "Jeff Stai" <[hidden email]> >Cc: "Elecraft" <[hidden email]> >Sent: Tuesday, May 01, 2007 7:35 PM >Subject: Re: [Elecraft] K3 inside photo > > >> Jeff Stai wrote: >>> >>> Here's a photo I took of the inside of the K3 at Visalia.

I know we are supossed to be sending these to Wayne, but I may need a grass
roots movement on this suggestion. I got back to CW this year, and am pretty rusty. I also started watching Jerico on TV. Every episode starts with a burst of CW - a little message pertinent to that episode. The code is 20 - 25 wpm, about half in the noise and not well sent. But, with my TIVO, I can back up 8 seconds and play it again until I get it. Ya think we could get a TIVO backup in the K3? 72/73, Tom - KJ3D _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

>Ya think we could get a TIVO backup in the K3? It's there... if I recall, I think the K3 offers 30-seconds of RX audio playback... maybe longer. 73, Tom Hammond N0SS _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
