[Elecraft] Dayton - Interesting Stuff - Maybe OT

Here are some things that I saw that were pretty cool.....

The Tokyo High Power 2.5 KW Transistor amp.  Running some 1900 watts output to a dummy load.  Interestingly, the unit does not have a regulated power supply and shows a very large voltage drop....50 to 25 volts on key down.  No fan noise although one was running.  Small too compared to a tube amp.  Price is rather up there, but if you compared it to an Alpha...well...I think it would be even.

SDR Radio.  Wow.  The HPSDR group was there showing their system.  So was a lot of others, Flex, Perseus, and a some others I did not get to look at.  The SDR forum was packed.  Had some good information about SDR.  I am sure these people have been there before, but sure grabbed my attention this time.  Interesting technology.  I think that to get into this type of technology right now you would need to know some programming and electronics.

Emtron Amps.  Now don't get me wrong, but I've been looking at amps for some time now and these look good.  What I have been discovering is that the Russian tubes are getting scarce because of production problems and Eimac tubes are getting up there in price.  I asked the guys where they are sourcing the tubes, and they said the Chinese are producing knock-offs of the Russian tubes which are knock-offs of Eimac tubes.  So, they said they could buy Chinese (aka Russian, aka Eimac) tubes all day long.

Then the high point, was the K3 and the second receiver.  That was cool to see that coming along.
