Nate, per email I received today, at 5hz, the fan should always be used regardless of output power.
Shawn was this Vladimir's recommendation? I have felt that any power output over 4 watts with 5 Hz needs the fan but it may possible to get by without at lower power outputs.
Nate how did you have the radio mounted? When it is mounted on a tripod the natural convection provides some cooling for it.
Shawn was this Vladimir's recommendation?
Javad and Vladimir both.
Nate, another question. What are you using to power the radio?

Did they say anything about the internal 1 watt radio for the TRIUMPH-1M? I thought this was checked and wasn't a problem.

Didn't think Beast was out for Tr-1M yet.
Would be interested in trying as I have a new set here.
I haven't had time to test again after a radio firmware update, but I was having trouble with both the internal 1W, and the external 35w radios overloading the rover radio at short ranges. May be possible this would help out.

You need the new TRIUMPH1-M radio firmware for 5 Hz corrections: FW_LMR400_ID74_Ver32_Rev04_B26.xmd

Power to radio is a 65 LB marine battery that is about a month old. Wanna carry it?
Mr. Gluting took a new 35W radio off the shelf, and fired it up, ran it a while at 4 watts. Just turned it warm. Ran it at .5 watt, and barely warm.
Mine gets HOT in 35 mins. enough to shut off.
Mr. Gluting said my replacement radio would be here Monday.
It's a bear of a way to start this game... intermittent radio is hard to solve. It works great until it gets so hot, then it SHOWS green at the ls, but the signal is waffled. Makes it barely work. Finally shuts down.
That's entirely the reason I was doing my testing at .5 watt. To be SURE it was working good, and not at 35 watt, and pulling lots of juice.

Radio was mounted as it is supposed to be.... Fan blows DOWN... for some of my testing. And, for most of it, it was sitting horizontal. At .5 watt.
Replacement be here Monday.

Michael probably already asked you this but what frequency were you broadcasting at? If the antenna is not connected or tuned correctly power will be reflected back into your radio and could possibly be the reason it is overheating.
Michael is sending a tuned antenna with the replacement modem. Once they receive Nate's radio, they should be able to isolate the cause.
Are you guys sure that it was actually broadcasting at .5 watts? After changing the output power you must press To Base to apply the changed parameters to the radio. In the screenshot below it shows the output power in red because I did not press To Base after changing the power to .5 watts.

Yes, we are absolutely sure. That is how it looks.
freq 461.025
base id 29
rtcm 3.0 min
mod band d16qam 25khz
i checked the antenna length.

Is the power output shown in red or yellow?

In yellow. I DID press send to base!
In fact, I went back to base, and Stopped it, and downloaded, and changed settings, to a higher power setting, (Earlier in the week) and SENT the new settings to the base, because I was not sure what was wrong, and why my radio signal was not as strong as anticipated. So, yes, I do know about how to do that. (now there are 13 other things I don't know, but I got THAT one!) Thanks for asking.
Yesterday, at the city park, I set it to 500 MW so that I could stay close, to base, and FIGURE out what was going on. It overheated, but BEFORE it shut down, (green TX light went off, and blue, bluetooth light went SOLID,) it refused to fix, for some 10+ mins, where it SHOULD have fixed. So, I think the signal was degraded... in some fashion. This is what has been stumping me.

Nate,
Might be typo and I might be wrong but you should be using 12.5 kHz for band here in US not 25 as your post stated.

Monte I was wondering that too. Is using the 25 gonna get us in a fix with the FCC?

The way I understand it, yes we are narrow banded in US and as far as I know FCC could enforce but I am not positive. We narrow banded all of our radios bout 10 years ago and have not given it a second thought till this new beast mode.

Yeah, just a typo.... {}
