Re: Looking for a reasonably priced 2m Bandpass Filter

If all you’re looking for is to eliminate harmonics that head up into the 430 MHz band when transmitting on 2 m just put a dieuplexer in line and use the 2 m part of it and don’t hook up anything to the 70 cm side. Most of them do about 60 DB if attenuation outside of band and can handle 50 W. And since you want to cheat, most of them are around $60.

Looking for a reasonably priced 2m Bandpass Filter

Everyone, I am looking for a 2m Bandpass Filter that is reasonably priced that is capable of 50W RF power. I am aware of a company in Europe (antennas-amplifiers.com) that has a unit, but it is currently outside my budget. I am also aware of using two diplexers system from Amsat. Is there any company here in the US that has a BPF that you could recommend please? Thanks Herb N4RG

Estate of Franklin Antonio N6NKF Commits Funds for Ultimate DX Search
by Joseph B. Fitzgerald 14 Nov '23

14 Nov '23

The SETI Institute, a non-profit scientific research organization, recently announced a philanthropic gift of $200m from the estate of Franklin Antonio, N6NKF. The funding will be used to detect signals of life and intelligence in the universe and share that knowledge with the world. AMSAT members probably know N6NKF best as the author of the Instant Track orbital tracking software that AMSAT sold for many years. Phil Karn, KA9Q, says "Franklin's personal involvement in the SETI institute as an engineering consultant took them a long way in the few years he was involved." https://www.seti.org/press-release/200m-gift-propels-scientific-research-se… de KM1P Joe
