This is the antenna up there for both digi and 440. It's either a 5.5 db or 5.0 db version. Pointed East. There is an unused antenna up there but does not tune well in ham band 2 meter

Tony WD0HXV and I N0QBH were out to the HHS tower site again today and this time we did a little more sleuthing regarding the feedline to the tower top 400' up. Much to our delight, we discovered the

There are radios with built in soundcards like the Yaesu FT-991A, Icom IC-7100 and Icom IC-9700 that do not require the use of an external soundcard. These radios are good examples of do-it-all radios

Belay my last. Looking at the photo tells me that would only work on the lower antenna. The upper is a 450 MHz (listen only).

This time it was off for 3 weeks or so. Thanks for the detailed info on the repeater itself. Believe me, that was hard to come by in the past. Since an earlier discussion was on cavity duplexers, one

How far back ar you remembering it being offline Mike? A couple summers ago it was off due to the Air conditioning not working and the repeater locked up. I happened to be in Willmar and checked on it
