Hello I have an LP-100 which I like very much. It's worked perfectly since I first built it and turned it on. I calibrated it, comparing to my Bird 43 and...
Hi Steve. Sounds like a simple problem. Since the rig still operates correctly, I suspect a cold solder joint on the attenuator PCB inside the coupler....

Hi Steve, My LP-100 displayed exactly the same symptoms as you describe after working perfectly for a number of months - right down to showing an SWR of 9.98...
You both probably have the same problem. I suspect in Barry's case the warming of the ferrite cores causes enough expansion inside the coupler to make a...
Some preliminary testing looks like one of the ADCs has gone away. I'll have to take some more time to go over this; sadly, time is the one thing I don't have...
Larry I'm not sure what I fixed, but, it's fixed. I inspected and re-flowed the connections in the coupler. None were visually bad even under illumination...
OK Steve. Also make sure that the mounting post for the voltage xfmr is tight... it acts as the secondary for the xfmr, so it is not just there for mechanical...
The LP-100A started shipping yesterday, and I expect to be caught up on orders in a week. I have posted a new manual for the LP-100A, and new VCP and Plot...
Thanks for doing the daughter board and allowing us to keep up somewhat Larry. Sounds like the A is a race car (2 processors??). I'll be interested in the...
One processor is dedicated to the display, to make it do some of the things it really wasn't designed to do, but that are important to me. The overall...
Sounds good. Let me know when you are ready and I'll send my unit to you if you will do this. I wanted to get a LP calibration as my unit has not been...
I just corrected a few errors on the assembly pages (9-12) of the LP-100A manual. The new version is E3. If you haven't started assembly yet, please download...
Hi Larry, I received my LP-100A #704 kit a couple of days ago and have started assembly. I am having problem with the initial checkout of the microprocessors...
Sorry guys I accidentally sent this message to the group by mistake. Please ignore. Mark ... From: Mark Gang <mark6sf@...> To: LP-100@yahoogroups.com ...
Hi Mark. Make sure you have the latest manual revision (E3). I posted a message to the list Sunday about some late manual changes. These included some changes...
I uploaded a new manual revision this morning (Wednesday, 1-16). There is some question about whether there were two versions of E3 uploaded, and one might not...
I have been working through a problem with the Plot program with Detlef, DL1GJ. The problem had to do with entered frequency limits not being properly...
It's looking like my K3 will ship in the next week or two. Once I have it for a few days to verify operation, I expect I will start taking orders. 73, Larry...
Larry, Don't forget that I am interested! I really like my K3 quite a bit. The LPan will be the crowning touch. Have you arrived at a price yet? 73 Richard...
LP-PAN is a software defined IQ direct conversion receiver which connects to the IF port of the K3 and supplies audio baseband quadrature signals to a computer...
Larry, Is this similar to Tony's, KB9YIG SoftRock IF lits? <http://groups.yahoo.com/group/softrock40/files/SoftRock%20v6.0%20docs/v6%20IF%20applications/> ...
It is similar, but has some important differences... LO frequency of 8215 kHz so the the display is centered on the K3 IF. The SR has an LO at 8192 kHz. The SR...
Larry, Assuming all goes well with the K3 testing, board and case fabrication etc, when would you expect to start offering a kit version. 73 Trevor G0KTN...
Good news! I got an email from Lisa at Elecraft last night (they must be working late) that my K3 should be here within the week. I would expect to start...
