Not important...you still have the QSK cult chant: "QSK...dead relay...QSK...dead relay...QSK...dead relay." If there were only a few more of you folks we could all buy stock in relay companies and

Do we have any idea how good the Inrad 762 might be at very close spacings? Let's take another look at the Inrad plot below. I've marked points below which show a total bandwidth of about 1300 Hz at

W5IZ: Well it was my home brew 352 that Sherwood tested...so that's one better than a 762. ;-) Yes, I meant the 762. 73, Bill W4ZV _______________________________________________ TenTec mailing list

Hi John, Inrad's upcoming mod for the VI+ should make it a stellar performer, especially with the 400 Hz roofing filter. I don't know enough about the Omni's to know if this will work for the Omni V.
Do any of you collectors have any idea what a Ten-Tec PM-1 is worth. A friend is selling equipment for a 90 year old blind ham and asked me what it might be worth. Please reply off list. 73, Bill W4Z
TT 1.8KHz filter, but the TT 1.8 should have far lower loss than the INRAD. ??? Something got lost in the translation here. When you said "performs", surely you didn't mean your 1.8 kHz filter has th
