2114? 1K * 4 bits?

I still have an unused 2.1 KHz Collins 455 KHz mechanical filter I bought at the Dayton hamfest years ago. Its a little narrow for voice, but it would be good for CW.

I still like Collins equipment, just not their poorly designed CATV equipment. I wish I could afford a R-390 and felt well enough to do a complete restoration. :(

Not really. Analog's bits are just smaller. ;-)

We've been getting half the way there every two years or so. ;-)

Nah - 2102 1k * 1.

Had 8 of 'em in in my homebuilt Nascom 1 computer which with a

2708 UVEPROM for the 'monitor' was all the RAM for system and user code and video store! Nevertheless, it was sufficient for a machine code program to run 'Lunar Lander', hee hee.

Collins filters were regarded as the bees knees in UK ham circles but I never could afford one!

Hello Tim,

Still, the digital guys kept telling us "Some day we'll get there and then you are going to be extinct". I am not worried at all...

The price was right, that day at the Dayton hamfest. ;-)
