There have been  a few cw output frequency counters over the years,
the neatest was from 'Jackson Harbor Press" in kit form. It fit in the
famous "altoids" can and worked to 180MHZ  I used it when Bill Gerrey and I
did the adapted MFJ 209 analyzer. The 209 has an R.F. output which drove the
counter fine.

Unfortunately later and fancier analyzers don't have this handy R.F. output
thus don't lend themselves to accessible external counters.

Ciircuits for VCO type meter readers and like can be found in Bill Gerrey
WA6NPC's 
Smith-Kettlewell Technical file. Published from 1980 to 1998, this now
on-line journal contains many still valid ideas for accessible simple test
gear along with an outstanding 
"soldering Series" detailing techniques for blind technicians to handle many
soldering jobs.
http://legacy.ski.org/Rehab/sktf/index.html

the problem we have with keeping accessible gear on the market relates to
the way modern capitalism works.  You build a certain quantity of product,
sell it as fast as you can, and unless demand is overwhelming, go on to the
next big deal.

That's how it works and that's how the entire economy is setup.  Until
somebody finds a different business model for small demand items, it ain't
gonna change.

Maybe the "DIY" folks, with 3D printing etc. will help towards a solution to
this problem, but it ain't there yet.

I have hope that Ron Milliman and his company will figure it out.
