Dennis Karksi estate (W9CWI)

At this Fest on Sunday, the friends and family of Dennis Karksi (W9CWI) will have a table at Sunday’s HamFest 2022 to try to find new homes for the gear that Dennis owned when he passed. The family has been struggling with Dennis’ large quantity of stuff for many months, so we’re passing this list on in the hopes that you might need some of this equipment.

Here’s the information that they’ve asked us to pass along:

There are many items on this list that can be had reasonably, especially if you can pick them up near Milwaukee, WI.  Quality discounts are available but will be proportional to quantity on many items (especially if you want all of the 440 receiver stuff, the telephone intercept equipment, or the pre-detection/recording playback equipment ). 

Some select items from this list will be for sale at the Dayton Hamvention, May 20-22 in Dayton, OH, mostly the items like the WJ-8999 & WJ-8969 receivers and the WJ-1204 and WJ-1250 frequency synthesizers. Shipping is available for some items but the prices will not be as low as for pickup in Milwaukee.  Some pictures of just front panels are available.  There’s too much in this estate to take time for more pictures or any additional testing.  All units are as-is unless noted.  No guarantees or returns.
