Capabilities of unmodified Maxtracs

Post by MP 6.7 »

Has anyone done any looking into how far out of band a 900MHz Maxtrac will go without hardware modifications? I'm looking to get one to do 932 and just barely north of 941.

That's what I plan on doing. I just need to know how far a 900 Maxtrac will go before the stock VCO becomes unhappy or I run into a filter...before I buy some.
