[ICOM] anyone have preselector experience?

[Adam Farson]

Hi Steve,

Yes, I am sure it will. That tuner probably has a pretty high Q.

A typical application for a tight preselector is in a shipboard HF
installation or a Field Day site, where multiple transmitters are operating
in fairly close proximity. You will not see much benefit unless you are
located close to another HF station operating on the same band as yourself.
The insertion loss of the preselector will not hurt too badly on 160, 80 or
40m where the band noise is usually 10 to 12 dB above the receiver noise
floor.

Roofing filters...that's a topic for another evening.

Cheers for now, 73,
Adam VA7OJ/AB4OJ

Hi Adam,

I hadn't thought of the tuner but it makes sense. I use a homebrew double L
balanced tuner. It might add some preselection as well ?

Thanks for the info about the loss. With all the talk about roofing filters,
I thought a tight preselector might be of some benefit. It would at the
least be something else to play with :-)
