Elecraft K3 K3S 400 HZ CW Filter: ELECRAFT K3 and K3S 400HZ CW and DATA Filter - KFL3A-400 -
Just removed it from a radio today.
$79.99 delivered - check, Zelle, PP FF ok.
A bit of patina on it,but works like new.
This is the most popular filter that I sell.

If you want to add a CW filter to your K3 or K3S,this could be for you.
Pretty simple to install.
These were $169.99 on the Elecraft site before they discontinued them.
Buy it here for less :)
Please see pictures of everything included.
If you need other K3 radios or options,I probably have what you need.
I can be reached through email if you have questions about this unit.

Ham Radio Control box ? Help ?: Ham Radio mystery box ? Someone knows what this is ?
$99 delivered - check, Zelle, PP FF ok.
This switchbox came with a huge load of Ham Radio gear.
You can see what owner was trying to control by his labels.
Maybe the inside board is a CW keyer ?
Please see Ebay or QRZ for inside pic.
Any help is appreciated,
