Re: Re: [Repeater-Builder] midland 13 -509 tx freq stability... cap change?

I bought a used 220 Maggiore Repeater a number of years ago and it had this 
setup for xtal. temp. control on both the TX and RX xtals. Not sure the 
manufacturer of the thermistors, but they look like what Bob is describing.

Re: Re: [Repeater-Builder] repeater location fees

[roger.white]

For many years, we had a $1.00/year roof top site (highest bldg. in the city) 
until years later when the bldg. management of the top floors changed and we 
were asked to vacate. Like a previous poster said, you could be paying next to 
nothing and a next door commercial neighbor is paying big bucks for the same 
location. That is probably why we got the boot. Our space could make many bucks 
a year. It's usually boils down to economics. Also, some hams are paying 
customers on the commercial side and get a "free" ride for their ham 
repeater(s). This is pretty common.

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.

Also, it seems like from reading about the part number decode table, this is a 
“Analog Plus” repeater. What does that mean?

I am anxious to get the manual for this. Is the main Motorola number the best 
place to order the manual?

Re: Re: Re: Re: [Repeater-Builder] MSF5000 C85GFB5203AT, Type GFB

[roger.white]

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!". I know that is a well-worn saying, but so truthful so often.

A few more things: Is the editing of this still DOS based or is it WINDOWS. I 
imagine if it is WINDOWS, it would be nice to use.

Where I bought the repeater, I was told no manuals were available. I hope I can

Re: [Repeater-Builder] Mirage D1010 Amp for ATV repeaters?

[roger.white]

We used one of these amps on our ATV repeater that re-transmitted Weather Radar 
images for many, many years in the Dallas/Ft. Worth area and had no failures 
that I remember. We transmitted into a circulator prior to the antenna, a 5 dB 
omni vertical, which was over 900 feet above the ground. Best I remember, we 
used it near its max. power out limit, backing off a little.

Re: [Repeater-Builder] Antenna on the side of a water tower

[roger.white]

For a water tower, I would imagine the backside null is rather substantial. A 
club I was associated with more than 20 years ago tried the side mounting of an 
2 meter antenna on the railing of a old style water tower (four legs supporting 
the "Ball". It performed as expected with deep, very noticeable (on the air) 
nulls off the back. However, if that is all you can get, then go for it. I have 
seen guys mount a Rohn 25 type tower on the platform where the railing is, 
mount the antenna on top of the tower section(s) and then the top of the 
antenna will see over the top of the water tower. I guess it should work. 
However. I bet there is a mechanical situation that has to be worked out to 
insure mechanical integrity during high winds. If you can bolt the tower top to 
the ball, that would help. I have seen that also.

Re: Re: [Repeater-Builder] 900 MHz MSF5000 up and running with CAT200 controller....

[roger.white]

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 omni which I got 
from TI. Since I do not have a tower at my house, the repeater just looks into 
a dummy load. I will haywire up the omni just to see what it sounds like with 
the two Spectras I have this weekend and then haul it over to the tower next 
weekend.

[Repeater-Builder] Excellant packing job by Repeater Builder member Jerry WB6NYS

[roger.white]

Just wanted to let everyone know I bought a piece of equipment from Jerry, 
WB6NYS, who is on this forum. The stuff arrived in "excellent" condition and 
the packaging was outstanding.

Many thanks again Jerry!

[Repeater-Builder] Best Place to by MRFXXX power devices

[roger.white]

I need to buy a replacement for a MRFXXX device I blew up over the weekend. I 
know RF Parts has these, but have no experience with them. 

Is there any other place you guys have used that you would recommend?

Re: Re: RE: [Repeater-Builder] dB224 220 MHz antenna up on large tower initial results...

[roger.white]

Yes, the antenna is Andrews (old dB Products) dB224JJ, made for 220 MHz. I 
never did find it on their website, but they still make it. I ordered mine thru 
Hutton Electronics here in Dallas.

It looks identical to the familiar 144-148 MHz version except, of course, it is 
shorter

Yes, over off George Bush, just south of the freeway, off Marsh Lane.

It took a little while to receive it, but I had the time to wait, since I 
ordered it in November and did not think we would go up the tower until the 
spring warm weather. This Monday was in the 70's and today, as you know is in 
the 30's! We just made it! Otherwise, it would probably be much later.

I agree. My other hobby is drag racing with my son driving and this statement 
is so true. I have relearned it many times!

The old saying, "Do it right the first time", is so true. The 3 dB antenna I 
bought a few years ago is only $300 less than the dB224JJ up there now.

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 
from the end of our street. Now, all I see are cookie cutter one and two story 
houses in Richardson (where my son's and I use to shoot off model rockets in 
the middle of grain sorghum fields!

Google found this:

The book you are referring to (written by a WA6 I think) is hard to get. Out of 
print for sure, but a very handy book. I used to have one but have misplaced it.

If anyone has a minimal knowledge of how a receiver and transmitter work, finds 
the squelch and the ptt line, audio out, xtal locations, etc.), it truly is an 
easy mod.

Re: [Repeater-Builder] 900mhz MSF-5000 for sale..

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.

I have the high-power (150w) 896 MHz trunking repeater (C85GFB5203AT) and it 
was easy to modify to the 900 MHz ham band. The repeater-builder website 
(www.repeater-builder.com, guides you through the steps to make it into a 900 
MHz ham repeater, with external controller. Bob M. did an outstanding job on 
this write-up and it worked the first time.

Re: [Repeater-Builder] 220 repeater antennas

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.

The antenna is up 300 feet on the side of a tower. Sorry.

Call Hutton Communications (www.huttononline.com/) in Dallas. I ordered a 
dB224JJ (220 MHz 4 pole) from them a few years ago.

[Repeater-Builder] dB224JJ Recent History of Ordering...

[roger.white]

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 have every 
year of putting up/repairing our hardware. 

Early in February 2006, we were notified of the upcoming maintenance date and 
we had to have our antennas ready to go up.

So, in late 2005 is when we ordered the dB224JJ from Hutton and received it 
early in 2006 (6 week delivery time quoted). That's not too long ago, but maybe 
to some it is.
