Great, how much do we need to raise?

Please email the list of equipment, including tower information.
I may have some stuff available.

Will there be an option to subscribe? I am assuming there will be ongoing operating expenses. Or will there eventually be a DI amatuer radio club to support it?

Great question. The ongoing expenses would be things like repairs and upgrades. AC power is currently going to be covered by Pat Kelly, if it gets out of hand it may need to be switched to solar but I don't think it would come to that. It would be really nice to see a DI A R Club, we will see what happens, maybe this will inspire more locals to get involved and get licensed!

If everything was purchased new probably $5k, we should do much better than that assuming we can find some used equipment, primarily the antenna array and duplexer.

What is the current state of the project and funding?

I'll see if I can round up any items and bring along to DOA.

I can offer a partial update - we went through the PayPal account a couple of weeks ago to determine what donations had been made through the GLFWDA PayPal account (linked from a "Donate" button on MSG website) and so far the donations are large enough to cover the cost of the electrical tape and wire nuts to complete the project....maybe not the wire nuts, just the tape. So if you are inclined to make a donation to help with this project, no time like the present!

Maybe I missed it or maybe it hasn't been advertised enough, but either way I didn't know they were looking for donations to help. I'll donote now. Should now be able to cover some nuts...

That's prophetic coming from you.:lmao:

OK, I did my part with the donation.

Update:

We have received $1000 from a ham club in northern Michigan and $500 from msg4x4club. We need other GLFWDA clubs to help the cause.

We have purchased two motorola radios to be paired for tx and rx. They have crystals that were sent out to be tuned, they might be back in time for DOA.

We have 50 feet or so of Rohn TV tower. We could use more if anyone has any to offer.

I am donating the rack enclosure for the equipment and 150 feet of steel winch line that has never been used. We probably use another 150 feet of steel cable for the guy wires.

We also need:

Duplexer ~ $1500
Antenna ~ $1500 (new but we are looking for used)
Guy wire ~ $400
Repeater controller ~ $250

I'll have to get with N8IT to get better detail.

Any funds beyond that will go to upgrades etc.

Thanks Gary!

I barely know how to use my radio, so I really don't know what any of those parts you need are. Sorry I couldn't be of more help. I may have some spare cable sitting at the house I could donate. Its not a 150 ft length though so I don't know if that matters. I believe I have the used cable from my old winch and I think (have to check) I may have the unused cable from my 9.5ti.

Any specs on the antenna?
Tower, maybe, but how to get it to DI from Ohio??
I'll look in to it.
Thanks for the update.

@DDS We could figure something out for transporting tower sections if you can get some.

Also, I have the model of the antenna mast we want, I'll look it up and post back.

It's 4 bay dipole mast, about 12 feet long.

I am heading up to Drummond from the Flint area on July 29th with a 12 foot trailer with room in it for tower sections.

from David (N8IT) a while back...

The Drummond Island 2m repeater freq is 147.96. It was issued on Sat, May
7 and we have 180 days to have it operational.

Basic antenna info, a 2.5 inch mast about 22 foot tall, weight around 40
lb and the wind load under 4 sq ft. Here is an antenna that a local club
has:
http://www.hol4g.com/ac/product.aspx?number=DBB-DB264-C&p=165900&sc=0

A good used duplexer will run $300 to $500 plus shipping. They
weigh from 50 to 75 lbs, so shipping can be high. The transmission line
only needs to be 1/2 inch hard line and we will need 6 connectors. The
repeater needs to be able to run 50 watts continuous output.

Where are we at on this, will it be up for DOA.

August 7th, 2011, 08:46 PM
There is a good chance it will be online for DOA but maybe in a temporary fashion.

Waiting on crystals for the radios right now. I think steel cable for the guy wires is the most immediate need, and/or cash.

Oh yeah, Dave said he will need to tune the duplexers which may take some time too.

What size cable and how long, and is there a local source that is the price range. could this be done during DOA.

What Lies Beyond Jeep Club will be sending a check to help on the Repeater project. Would we send it to GLFWDA with a notation for the DI Repeater?

Just talked to Pat Kelly, he is working on that, and yes, as of right now I want to raise this tower on Thursday but I need to talk to Dave to see if that is possible.

Glad to see it is underway.

What is the #6 wire to be used for? Internal bonding, external grounds, groundplane radials? What type of wire is needed? Insulated or bare? Used OK? Spliced OK? How much and what lengths?

I think stranded bare wire is what we want, it is to be used for ground radials, from the sounds of it, getting a good ground with just rods is impossible. Used is OK, I'm not sure about spliced, I would need someone with more expertise to answer that one.

Yes #10 or larger bare stranded wire in 50 foot lengths or longer to make ground radials and we need about 1000 feet or more and we also need 100 feet of # 6 wire to bond to a nearby well.

Did this repeater ever get up and running?

I came across this while doing some research on DI for a trip i'm going on in a month.

If it's up and running, does the repeater have an autopatch?

JerryD
September 7th, 2012, 03:15 PM
Well, I looked a bit online and from what I see, yes it's active but no autopatch. 147.36 w/ pl 110.9

Anyone use it yet?

Yes! We used it up at Drummond Off-Road Adventure 2012.

Coverage was pretty good, I made contact with repeater out and the stair steps at marble head. There are "shadows" throughout the island where you just can't get good reception, I think shale beach is one of them, but if you drive up the trail a bit to get out of the low area you can hit it again. for what it is worth, I was using a Yaseu 2900r with a Metz 5/8 wave bottom load whip (Michigan proof 2 meter antenna and only 37 inches long!) so with was pushing 75 watts when out on the edged or in low signal area.

I apologize for not being as active on here this summer, went through some rough times with with a close family member. I hope to be more involved now.

Wow I'm surprised you couldn't hit it at 75w.

Unfortunately FM is primarily line-of-sight. Repeater antenna height, mobile antenna height and terrain all play a factor.
