[Elecraft] K3 question re dual receive

I'm confused. I've assumed that the K3 sub-receiver must be connected to a second antenna - a luxury many don't have. However, as I read more I'm starting to wonder if the sub-receiver can be used for dual receive even though you are using one antenna? Is that the case or have I just exposed

[Elecraft] Why buy a K3

I've been off the reflector for months, and off the air for months, and about to get back on. Now am seeing the K3 seeming to take the world by a storm. In a nutshell, other than perhaps a second receiver - what benefits does the K3 really have over a K2 - (in layman's non-engineer language

[Elecraft] update on any changes to late serial #'s re. rx audio?

I have been away from K2's for perhaps a year and am considering building again. The only (and I mean only) frustration I've ever had with K2's is the lackluster audio (a subjective observation) which has been a subject on this reflector. My way around it in the past, to a point, was judicious

[Elecraft] K2's and switching power supplies

Hi folks - I would like to know what experiences anyone has had using switching power supplies within close proximity of a K2 or K2-100. I'm considering building a fifth K2 (keep selling the dang things to people that don't build) and am toying with the idea of making up a portable module

[Elecraft] K2 has one freq with low swr - all others fine - what to check

Hi all - I have a K2 connected to a separate KPA/100 - KAT/100 box. Any frequency on my rig will tune with an SWR of 1.5 or less EXCEPT in the 7.200 MHz area where it only hits about 3.7 - 1.0. It seems odd to me that only such an isolated freq range would do thisso it makes me wonder if

EXcellent thought! Steven Pituch wrote: Hi all, I was looking at my KPA100 while waiting for some parts and am wondering. Since the KPA100 is in the EC2 case, I'm guessing there is no reason to put the speaker in the EC2 by screwing it to the heatsink of the KPA100. What if I found a

[Elecraft] KPA100 - left, right, counter clockwise?

Hi folks - I wonder if somebody can confirm part of the instructions on page 47 of the KPA100 manual. I have the KPA100 connected to my K2. The KPA100 is lying with the heat sink down and the fan to the rear next to my K2. In this position all component labels are upside down. The errata

[Elecraft] Why is K2 so easy to send cw with?

Hello fellow Elecraft addicts - I've been using my Icom 706 a lot lately while I build the amp for my K2. As an 18- 20wpm cw novice I seem to have FAR more difficulty SENDING cw on the 706 then I do on the K2. I could swear it's not my imagination. After 30min on the 706 - a switch over to

[Elecraft] KPA100 in EC2 question - any reverse steps?

Hi folks - I am at page 21 of the KPA100 manual. I will be placing the am in my EC2 with the KAT100. My K2 is number 4667. On page 21 it begins to discuss the internal ribbon cable connections. My question is this. If I follow the KAP100 manual will I have to reverse any of the steps from

[Elecraft] power to remote KPA100/KAT100 question

[Elecraft] K60XV alignment question

Don Lerche was right and I thank him so much! Although I could not SEE the short I disconnected the T4 windings one by one until the Q7 base resistance shot up to 2.6k. Then I resoldered one by one - measuring Q7 after each new solder joint. Finally I redid all of the page 71 measurements and

Hi folks - Could some one bring up to date on what to expect for drift if I build a new K2/100 vs a K2 with the 100w amp separated? My understanding is that initially it was a better idea to keep the amp separate - that combining it in the box with the K2 increased drift - a bit frustrating
