Mike, On the 220 cavity conversion this would be excellent posting on the board info sheets. Might consider giving it to the board moderators or posting in the FILES section. 73, ron, n9ee/r --- In Repeater-Builder@yahoogroups.com, Mike Mullarkey [EMAIL PROTECTED] wrote: Hi David,

I am fairly good at making documentation, and if this project works, I will create a PDF complete with pictures and dimensions to help others who may want to do this in the future. I have learned: 1) I do not need to cut down the casing. The only reason to do this would be for sizing. 2) The

2) The connectors used on the ResLok duplexers are easily uncrimped and shortened, which means no additional expense for RG-142 cabling. I've had good luck re-using those in-line tee connectors that Sinclair likes to use by slicing the crimp ferrules length-wise using a Dremmmel and then

Hello Dave, The length of the cavity doesn't effect its operation so you won't need to shorten it. Scale the cable harness down to 220MHz. Using a plier, you can work the crimp to be round to loosen it to be reused for soldering. The loops could be made shorter but may not be necessary since
