Here are some of the items I picked up at the Vienna (Virginia) Wireless Winterfest this weekend.

The DAs are interesting. Not only to they provide multiple 10MHz outputs but they also provide divided outputs (5 MHz and 1MHz).

I don't know what I'll use the filter for. It's 30MHz wide (full transponder) @ 4.183GHz. It looks cool though 😺

@vk2bea So many treasures, so little time… Curious to see a filter response on the cavity. Had never heard of the Logic Dart before. Looks interesting. (Have some of the simpler HP logic probes, but not the logic pulser.) Did you see the DIY Dart probes post over on eevblog? #HamFestTreasures #TestEquipment

@n8dmt The filter came with a plot...

I have the logic probe, pulser and current probe set. The 'Dart' came out in the 90's as their successors (I think).
This Dart came with all the probes, in good nick, so I don't have to reconstruct them. Handy to know its possible to replace them though.

Sometimes you walk away with nothing and sometimes you find gems. All this lot cost about twice my petrol bill to get there (and I drive a small car)!
