[CQ-Contest] ICE vs. Dunestar, Bandpass Filters

Several major contest stations are now using transceiver bandpass filters
(good for 200 watts) designed and built by Ed, W3NQN. About 3 years ago I
went to Ed after having problems with ICE filters and he came up with a very
solid design.
He does not make a switchable filter set, all of his units are single band.
So there are 6 small boxes for 160 thru 10.
The performance specifications are superior to either Dunestar or ICE.

WX0B is now making a multiband switched filter set based on the W3NQN

W3NQN does not have an email address. If you are interested, please send me
an email and I'll pass it to Ed.

I will be bringing a few sets of transceiver bandpass filters, Ed's new
powerline filter (7 amp) that KR6X suggested as a good isolation solution
and a few of Ed's new high power (1500 watts) band specific low pass filters
to Dayton. Please let me know if you are interested

I am not a reseller for Ed, I am just trying to help Ed sell a few filters
in appreciation for all of his hard work designing filters that most major
multi multi stations now use.

I hope that helps.
