This was the third amateur radio that graced (shortly) my control. At the moment, I can't seem to find any information on the exact model I had. All the internet information lists the radio with the 7.2 volt battery pack. But I know for a fact that it came with a 12 volt battery pack (that was larger than the standard battery) that pumped the TX output to 6 watts (measured with the swr/pwr meter when I was building my first J-Pole antenna). I really enjoyed using this radio, especally since allowed for me to listen to both the 2m and 440mhz repeaters on campus at the same time. This was very important, because it was an easy way to confuse other members of BARC (who usually only had 440mhz radios, espcally if they were on loan from the club). Although the shape was a little strange, it actually fit very well. I miss the traditional shapes of a HT. There is just something specail about the HTX202, ICOM IC-02AT, etc. Unfortantly, the ICOM guiding spirits decided this radio should not be mine. I had it cliped on my weathers jacket while going to do race committee. Originally I was going to talk to shore and coordinate more between the race-course and shore, but unfortantly we had troubles with our motorboat's engine... and silly me hung my body over the back edge of the motorboat, and the radio sprung from my safety into the water. I really think that is what really killed my intrest in amateur radio, since I stopped taking my HTs with me everywhere I went. Not to mention losing a $400 radio into the water after only having it less than a year really downed my existance.
