I don't know if the pool is posted (ARRL might have it) but this site: http://www.eham.net/exams/ will give you a practice exam and then mark all the correct answers after you take it
Thanks!

I feel left out. Y'all need to move closer to the Pioneer Valley.
LOL ... Turbocharger just timed out the Paxton repeater....its a 3 minute timer! LOL
Who, me?Boy that guy was clueless!!!!! LOL
Gonna time out again!

Man, sounds like you guys had a good time. I'm now up and can't sleep... Too bad I just didn't just stay up and talk with you guys...

Noob here, what does this mean ? Are you limited to how long you can use a repeater ?
I'm not on the air yet it'll be awhile before I can afford a rig.
Yes. Most repeaters have a "time out" timer, usually set to around 3 minutes. It prevents someone from hogging the machine, and also acts as a watchdog timer in the even to a malfunction. When you release the PTT, you hear a short beep to let you know the timer reset. So, if you are going to get long-winded, you have to be aware of the timer and drop the link periodically to let the timer reset.
That also works if someone has "gone clear" and sets the mic down...it falls between the seats and stays pressed....so you can hear them swaring at traffic...bitching about something they see on the road...it's quite funny.
Well its a good thing I spotted this ham link on NES. My license was about to expire in a few days. Forgot all about it and it would have died. I did renew on line.
We need to beware of any government site that says it's easy to do something on. I am glad they had a telephone hot line to talk me through it.

Yea, god forbid you miss this thread...you know...two years and 155 pages of posts...
Yes, we need a sub forum. C'mon C-pher, I know you and Derek are best buds....get it for us.

I think I need to install a fan on my Kenwood TM-2570A...
After the very long conversation with NX1Z last night, my radio was quite warm. Not dangerously so, but it was approaching the point that I couldn't touch it. It was on low power (5 watts), and I can only imagine what would happen if I transmitted for an extended period of time on high power, which is 70 watts.
I just need to find a way to only have the fan come on when the radio is on...
That shouldn't be happening. Is it in the clear, and not blocked ventilation wise? And are you sure of the match to the antenna?
I don't have an SWR meter, so I don't know how good the match is, but I know it's a 5/8 wave 2 meter antenna.
There is nothing covering the heatsink.
The conversation we were having lasted for over 2 hours if I'm not mistaken, with me doing most of the talking. After 2 hours, I'm not surprised it was warm/hot.
I could still touch it without getting burned, and I may be exaggerating how hot it was.
You have to understand my background with heat and electronics. I own a high performance computer, which is significantly overclocked. I am quite obsessive about keeping electronics cold. So much so that my computer has a liquid cooling system, and I get worried if the CPU temp hits 35C (the maximum recommended operating temp is 61C).
I like to keep the temps well below dangerous levels. Does anyone have any ideas for having the fan come on only when the radio is on?
... I also mentioned that you were looking into getting us a club call...
Understood. That was a lot of time operating, and I'd imagine the heat sink on the unit is fairly beefy, so it'll hold heat for a while after you stop transmitting, so the cumulative effect of 2 hours on the air is going to be fairly significant. Even the back of my FT817 was warming up more than I'm used to it doing, not operating FM too much, and I was kind of being fascinated by that while I was talking to John and Matt last night. So, unless you're hearing a sizzle when you wet your finger and touch the heatsink, which was the impression I was almost getting from your description, it's probably normal. You should get a ballpark for the SWR -- doesn't the rig have a built in SWR meter? The problem is 2 meters is a big band, so knowing where the antenna is tuned to is important. If you bought it second hand from someone who was using it on their car or something to work 2 meter repeaters, then you're probably ok, assuming they tuned it. You probably won't damage the rig anyways as it'll fold back to protect itself, but no sense taking chances.
N1NES jumps off at me as "nines"; My vote is for K1NES then A2NES.I kind of like N1NES and K1NES, as they have the best rhythms in Morse Code. A2NES has a pretty good beat too.
He wasnt just heating up his own radio..... he is so long-winded the repeater had to take a break a couple times!....LOLOLOL. Sorry Turbocharged, I couldnt resist....LOL.

Sorry to bust the bubble, but I think you will find that they don't issue 1x calls beginning with A.

Hey, I did all I can do and ask... Now we just wait and see what the Mod's say... I also mentioned that you were looking into getting us a club call...
