[TenTec] 216 Filter FS/FT (was Mystery Filter)

[n1eu@yahoo.com (N1EU)]

Thanks very much Mike - that's fast detective work!

If anyone is interested in buying the 216 filter or
trading a 218, 219 or 221 filter (1.8khz or 250hz
9Mhz)for it, please drop me an email.

I also have an Inrad 755 filter available (2.8Khz,
6.3Mhz if) if anyone is interested.


Thanks & 73,
Barry N1EU
