Range test map from today. TRC-212 to TRC-212




This tool (http://www.daftlogic.com/) shows our test was just over 5.1 miles today. That's not bad for 4 watt portable-to-portable.

As usual...click the image for the large version.



The map shows the whoppin' 5.1 miles we covered today. Maybe could have gotten 6 miles out of it, but you better not have much noise in the area and you better yell into the mike and find the perfect position for both radios.



I'm pretty happy though...I think that's a good haul for "HTs" on 27Meg. Kinda feel like a doofus using the huge radio with the huge antenna. People probably thought I was doing some casting practice with a fishing rod!

Both radios appear to be working fine..when they both work at all. The one radio is intermittent. Seems like an osciallator is kicking out somewhere. When the one radio goes south, there's only faint noise on Rx and no output on Tx. Guess that radio gets to go on the bench. Good project for winter time.
...along with the Messenger 323A that will be here on 02 Dec 09.



AM.....it's certainly not like FM! Not a lot like SSB either. Sure can tell it's not a real efficient mode. The 212's have pretty good audio though. Nice and crisp TX audio helps punch through, but I think they are currently a little weak on modulation. I'll have to test the TX side on the bench and see how much power I'm getting on Hi and Lo power and how the modulation looks on the scope.



Doug and Crystal were the ops on the Kasota end of the circuit today. The picture above is of Doug and Denny (official observer). Doug he had the radio on top of the car..I didn't think he meant that HE was on the car. Putting the radio on top of car helps serve as a ground plane. He was just getting more elevation the way he did it.

We had to QSY from Ch. 30 to Ch. 31 due to "skip" stations on 30. Maybe that was a bad channel to pick. Guess I should have used 4 to see if any 4x4s were out there...or maybe Ch. 1 to see if any GoldWingers were out there.
\\ No pictures of Crystal since she was taking the pictures.
