Engineer's Log of Mark W. Persons
Touring the NAB Convention

Paula and I attended the National Association of Broadcasters' convention in Las Vegas. 
About 98,000 people from all over the world also showed up to see the latest in broadcasting.

(l-r) Tom King MSEE and Bobby Cox PhDEE showed off a phasor system designed and built by KTL (Kintronic Labs). 
It was sold by M. W. Persons to KGFK Radio in Grand Forks North Dakota.
AM phasor designs from KTL are the best in the world. 
Tom is president of KTL and paused just long enough for a photo.

It was a busy convention.

Then we headed to the CPI booth.  You know them as Eimac transmitter tubes and Econco tube rebuilding.
(l-r) Lourdes Ramsey and Debbie Storz of Econco, then us (Paula and Mark Persons). 
One of the displays showed a 4CX5000A tube as it often looks upon arrival at Econco for rebuilding. 
Then some of the components inside and finally a completely rebuilt tube on the right with shiny nickel plating.

Paula discussed the rebuilding process with Debbie.

Gorman-Redlich was represented by Jim Gorman and Don Walker.
Jim built EBS (Emergency Broadcast System) equipment starting in the early 1970s.
He has updated it to include EAS (Emergency Alert System) and CAP (Common Alerting Protocol).

Jim and Don are very knowledgeable on the subject.

Then it was over to the Electronic Research booth to see the latest in FM broadcast antennas and to say hi to Tom Silliman.
What an interesting guy.  Tom is President of ERI and loves to climb towers.
The joke is that if you can't find Tom, then just look up...he is likely on the nearest tower!
You might have seen him on television recently climbing to the top of the Empire State Building.
Paula and I were happy to visit the Orban booth.  Interestingly, we sold four Orban Optimod-5500FM Digital Audio Processors in a two weeks recently.  It made the folks at the factory busy trying to keep up with orders.  We price the gear at 15% off list, which is the Orban minimum allowed resale price.  Customers love the processor for their FM stations and the $3,391.50 price.

CRL (Circuit Research Labs) is now owned by Orban, but is no longer manufactured.  We are very familiar with CRL because we were their first dealer back in 1978.  CRL gear is repaired today at M. W. Persons to keep it running to factory specifications.   

The stories go on and on.  Stop in again sometime.  I'll leave the soldering iron on for you.
