Re: [TenTec] Paragon II Failure to Transmit

[Peter Bertini <radioconnection@gmail.com>]

I may be missing something, but I don't see how the 455kHz mechanical
filters can do much to improve the 2nd mixer in band IMD performance for
the Omni VII. The limiting factor is the 70 MHz 1st IF filter which has a
wide 20 kHz BW. It looks to me the same problem when comparing in close CW
performance between my Omni VI and Paragon II. The Paragon has the same 70
MHz 1st IF problem and lack of early protection for the second mixer.
(Besides the phase noise issues).
