[TenTec] Omni VI version 3 - which Inrad filters to buy for CW use?

[Chris Wagner]

Hello

I'm Chris, presently HS0ZFE and in Nonthaburi, Thailand. Yesterday, I bought
an Omni VI on eBay.
It will be my first TenTec transceiver. Although I admire the company for
its continued support of amateur radio.

Without the manual, I was unable to use a modern handheld Kenwood radio,
unable to go to a simplex frequency.
Anyhow, my expectations are high. and the seller knocked off $ 300 for the
filters.

Q1: the seller says, the Omni VI needs *2* 250 Hz filters, not one. why?

Q2: should I choose the 400 Hz filter instead, as a beginner?

I would be happy to call, if someone prefers talking to typing. Here is my
