Re: [Repeater-Builder] DB-4072 duplexers

I tuned one at one time on 447.05/442.05 and it worked well. Don't remember the rejection numbers though. Gary - K7NEY On 2/5/2010 9:52 PM, James Adkins wrote: Wondering if anyone knows if the 6-cavity set of DB-4072's made for 450-470 MHz will go down to 444.425 MHz / 449.425 MHz? I know

[Repeater-Builder] DB-4072 duplexers

Wondering if anyone knows if the 6-cavity set of DB-4072's made for 450-470 MHz will go down to 444.425 MHz / 449.425 MHz? I know the specs say only down to 450, looking for anyone that's tuned these in the real world and how low you've tuned them. Thanks, -- James Adkins, KB0NHX

Anyone on the group here moved a set of DB-4072 cans down to 443 MHz on the low side. What issues if any should I expect? Cables changes or not etc. Thanks Randy
