I asked our club trustee when we ordered the dB224JJ from Hutton. It was in
November 2005 and we received it in the Jan. 2006 timeframe. The reason we
remember that date was that was the date we had our yearly maintenance on our
tower we have our club antennas on and that is the only chance we h
Call Hutton Communications (www.huttononline.com/) in Dallas. I ordered a
dB224JJ (220 MHz 4 pole) from them a few years ago.

Hutton Communications made the old dB Products dB224JJ 3-4 years ago for me.
It was not advertised at the time, but I talked to them directly and they made
it for me. Maybe call and ask.

You may want to give out the p/n of the units, so that one can tell if they are
the analog (CLB) or digital (CXB) programmable units.

Well almost up! It is at my house in Murphy and will be over at the tower in a
few weeks. I am going to run it across the IFR we have at the repeater building
first before I hook it up to the antennas at the tower. I will play with it a
few days at my house, but have no antenna other than a 3 dB

That is exactly what I hoped I was to do, but because of my total ignorance of
this facet of repeaters, I was not sure which way to go. You have pretty much
told me exactly what I want I need to do.
The outlay of a few $100 is minimal if you get what you need to "Do it right
the first time!".
Many, many thanks, Bob! Some GREAT info all in one message. I really appreciate
it. This gives me some great confidence building info. I am from the old school
of just ordering some xtals from IC and tweaking it in! Guess those days are in
the past!

OK, thanks Mike and Bob. I have been subscribed a little while to the groups
you are talking about. I thought I would get some good info from you guys that
have a ton of experience on this type of equipment. I just did not want to get
spun off in the wrong direction on this venture.

I bought a used 220 Maggiore Repeater a number of years ago and it had this

Oh, sorry. I live in Murphy (basically on the east side of the Richardson/Plano
city limits).
The good ole days of a pleasant commute are gone. When I moved to Murphy in the
mid 80's from the Garland ghetto, I could see the skyline of downtown Dallas

I agree. My other hobby is drag racing with my son driving and this statement

The old saying, "Do it right the first time", is so true. The 3 dB antenna I
