pull a set of helicals out of a Micor mobile. a high split will do fine. If you need to locate some contact me off the list.

Even moving the WX receive antenna away from and behind (it's directional) the 2m antenna didn't help. The solution was to connect a small Sinclair preselector in front of the WX receiver. These little gems are about five inches square, and have four helical resonators. I tuned it to the WX frequency, and eliminated the 2m interference. Preselectors are not cheap, but DCI will make you a nifty filter, similar to the ones for 2m, that passes just the NWS frequencies. It'll cost about $100, since it's a custom model. 73, Eric Lemmon WB6FLY Don wrote: > > I have a lot of Non Ham friends who use the Mur Freq 151.820 taking their > HT To Little League Games Camping Etc , And I was going to set up a Legal 2 > Watt Narrow/band FCC type accepted Radio , Whew had to get that out of the > way first. > > Then tie that into My 440 repeater that I rebroadcast the NWS and Amber > Alert Warnings . well the Testing I have done The Two Watts .
