A couple more hams have checked in so we're looking good for commo for the rally. I have been making last minute tests on equipment and tuning antennas for a couple of days. Today the AM-4477 amplifier refused to pass a receive signal back to the PRC-77. Luckily it was just a sticky K1 relay...

Really sorry to hear that! Bob

It's easy and safe to use a 12 v vehicle to recharge (not 'jump start') a 24v pack. As said, just charge one 12v battery at a time. Positive to positive and neg to neg on each battery in turn. Do not connect chassis to chassis. 10-15 minutes on each battery would probably put enough power...

It sure is going to be fun! This is only my second year so don't know that many people. Be sure to stop by the 404 Unimog radio truck and say HI! Then do that again several more times and I might remember who you are LOL. My wife says I have CRS. Bob Tennmogger WB4ETT

Scary. With the truck pto engaged, the moment the dog clutch is engaged there is no safety factor (with no one in the cab). That dog clutch absolutely won't disengage if it gets a load on it. If that single person cannot make it into the cab, something gets busted or that person loses a leg...

Hi Fireham, This is great! As the date rapidly approaches it'll be good for people to post what equipment they have that's actually operational and going to be there! I'll try to monitor 146.52 MHz as I approach Thursday also. I'll be driving down from near Knoxville on Thursday in my 404...

Thanks Mike, two radios makes one comm link! Do you know what frequencies your CPRC-26's have in them? Bob

As we get closer to the GASS Rally (now isn't more descriptive than SSGA?!) let's find out who has operational and tested VHF green radios. Commo central in camp will have PRC-77 with AM-4477 amp, and elevated antenna. Several other people have said they are bringing base station equipment...

If someone had done the exact swap you want to do, seems they would have chimed in by now. Personally, it seems you hate that engine. I can't imagine why anyone would put such a hated engine in any truck they had!! I don't think you will be happy with it. I have an old 7.3 IDI NA engine in a...

Thanks for all the offers to help and bring equipment in preparation for a communications net at the great Georga SS gathering in Durhamtown. It's hard to believe we're just about a month from the GA SS event!!! Let's concentrate on getting our wide area net on 51 MHz, using green radios if...

Obviously the flag could have landed on the ground if the young lady had not caught it and hugged it securely and affectionately to her person. ...several times. She must be commended.

Hi, Welcome to the Unimog sickness. There's no cure. Add the green vehicle sickness and you are hopeless. You'll enjoy your radio truck. I have enjoyed mine for 13 years! You might be surprised how convenient a package the 404 Unimog is with the radio box left intact. A great package...

Check out BergTires.com Home Page - Thousands of Used Tires - Military, Industrial, Large Truck, Heavy Equipment They are good to deal with and are in this end of the country. Unless, of course, Jack has already helped you find one. FWIW, I have cut the sidewalls in too many Michelin XL...

Most anything you hook coax to will radiate some signal, and if you manage to tune it for low enough reflected power, the radio won't mind. But, why would anyone tune an antenna, much less a pair of antennas, 'off' the vehicle they will be used on? Why connect two antennas in parallel...

29.6 to 29.7 is the FM sub band on 10 meters so your FM (isn't it?) receiver can hear the modulation. If you live near a population center there's a good chance there'll be a repeater there. Tune around at whatever step size your receiver has (50 Khz, 25 if you're lucky) and see what you can...

Yeah but we'd have to chrome our wheels to match those shiny knobs. They must have run out of paint.

Thanks for pointing out the size difference!!! I thought we were talking about similar sized tires! Bob

I run 14.5 x 20 Michelin XL's on my U-1300 Unimog (German Military transport truck). These are on 20 x 11 wheels so a wider wheel is no problem. This is a 14,000 lb truck with the camper (little over 7000 front, a little under 7000 in rear). The XZL's are a similar radial tire carcass, just...

I'm just below Knoxville too! Wave and I'll see if I can spot you!! Seriously, if you are in GA then I'm really not close to you. Bob

You bet we can help you check out the PRC-10. But please help me out a little, what's an "er79"? [edit: also what is an Oe 254 ?] I got my PRC-77 in the mail yesterday and today I got it working and on the air. It talks to the SEM-35 just fine. I am lucky to have another ham nearby, my...
