HTX-202 Output

[KB1PRX]

I Had To Sell All My Equiptment Now All I Got Is This HT I Traded For And Yes I Knew There Was No Output. I Just Didnt Know Why?? I Programed It Just Like My Old One.(HTX-202) But When You Key It The Bars Dont Go Up And It Doesnt Transmit At All,On Any Freq. My Only Thoughts Would Be That The Outputs Are Bad? Any Thoughts Would Be Greatly Appreciated. Since Im Out Of Work Im Very Limited. Thank You And 73, KB1PRX

TX Lock Out? (Well, you could always hope it's that simple!)

I Did Check That But Thank You Anyway.

Is It Possible That The Antenna Connection Has Come Loose On The Inside Of The Radio?? Sometimes The Connector Gets Loose And Turns, Breaking The Connection.

Ok, that's a pain and makes typing pretty slow for me. Thought I'd give it a try though.

Anythings Possible Ill Check That Thank You

I Checked The Ant Connections And Their Fine I Think The Problem Might Be Something Shorted Out. Someone Got Inside To Replace The Internal Battery
And Did A Real Bad Job At That. Im Not Too Optimistic Anymore After Seeing That Mess. For Now I Put It Back Together Until I Can Order A Battery Holder Like WB3GCK Did That Looked Like A Clean Job. Then Ill Have It Looked At.
I Cant Send It Out Looking Like That. Thank You For All Your Help. I Guess
Ill Be Off The Air For A Little Longer. 73

A story goes around about those that they don't like to be operated with 12V connected in the top jack while a battery is installed - because a zener diode in the regulating circuit gets too hot and overheats the final amp.

It seems a bit fishy to me and I don't know how much there is to it - I've never been into my 202 to see where the parts are but supposedly the diode and the final are physically too close together, but the diode can be repositioned and supposedly that was routinely done by service shops.

Of course if the final is cooked it would probably be not worth repairing, but I have seen (and it would depend on the construction) finals that were thought fried that just needed resoldering, but that has been in higher watt stuff than a 202.

It would be nice if you could bring the rig back to life with a simple fix - they are a nice, tight HT, if a bit of a bugger to set up the memories and so forth with their somewhat cryptic button labeling.

http://www.repeater-builder.com/rbtip/ has a lot of info on the 202 including this: http://www.repeater-builder.com/radi...ent-tx-fix.txt a tale of poor grounding at the antenna connector which maybe of interest to you, as well as complete service manuals & parts lists.

Good luck!

I too have heard that one from a dealer in a popular ham radio shop.

Another thing to look for that I can tell you from experience: The metals they use in the radio contacts and the stock antenna center pin don't seem to like each other. I used to get this yucky black corrosion on the center pin of the antenna that broke contact, I kept having to scrape it off to make a good contact. Perhaps it might have caused the demise of your HTs finals. When I went with an after market antenna the problem no longer occurred.
