    Default TH-28A: good 2M radio? i seem to have acquired one.

    I have acquired a TH-28A, it was a bit of an impulse purchase as the eBay time was running out. is it a good hand-held for 2M?

    Did the manual come with it? If not, download one (many sites, Google is your friend). I found some information on the 28E, but sometimes that suffix letter means something totally different. Be sure the manual is for the exact radio you have.

    the manual i have downloaded is: http://www.radiomanual.info/schemi/TH28_TH48_user.pdf
    it is a poor quality scan, but usable. best guess is A = everywhere, except Europe and U.K, and E = Europe and U.K.
    there are a few button location differences, but otherwise, i think, the same.

    I'd say that's a keeper!
    I'm more of a dual band guy and won't buy a single band radio, but if the price was right, I would have jumped on that.

    I received my TH-28A today, and i am quite pleased with it. with just the rubber-duck antenna, i was able to receive a fairly distant transmission. i was blown away with the reception. i figured for such a little radio, and being inside my house, that i would need an external (to the house) antenna to get anything.
    I also bought a cheap little antenna for when i am inside my car, though it has a SMA connector, and my radio has a BNC... not really what was stated on eBay. good thing it was only $12.

    i already messaged the seller.

    Quite right,

    A = Americas
    E = Europe

    The main difference is the channel spacing, 5kHz for A and 12.5kHz for E spec...

    [edit] $80 is a bargain compared to the new retail price back in the 90's...

    My TH-28A seems to have developed a short in the external speaker jack. so i opened it up. I am ok with larger circuits, but not so much the micro circuits. I may have to break out my magnifying lamp to see what is going on.
    Should be an adventure.

    well, it turned out to be a number of issues, none of which was a shorted external speaker jack. though the jack needed some cleaning. i also had to clean and bend down the contacts for the battery pack for better conduction, and the BNC antenna connector in the factory antenna is worn, so the antenna keeps popping out of lock, and making weak connection.
    so it was an easier fix than i thought. the antenna i will likely replace, though right now i have a piece of tape to keep it from unlocking.
    it presented symptoms of a short, but fortunately it was not. though the included NiCad battery pack needs replacement, as it no longer holds even a 10 minute charge. i have the AA battery pack for backup, but i prefer re-chargeable.
