Default How long can a radio last?

HI ,
I have a futaba T6xa\h radio for about six years now and it works fine. My question is how long should my tx last and Do I need to consider getting a new one ? Exept changing the Tx batt is there anything else that I should replace (Maybe crystal for example)?

The only things in a TX that can't be expected to last at least a few decades in normal conditions are the battery and the moving parts (potentiometers and switches).

When I wroked in electronic design engineering years ago we worried mostly about electrolytic capacitors drying out after about ten years. Modern parts may be better. I have a 20 year old transmtter that seems to work fine but its so outmoded that I don't use it.

As mentioned above, other than electrolytics or mechanical parts wearing out, should last for decades if given reasonable care. It would be wise to occasionally have it checked out for frequency stability (allowable sideband suppression) and any drift due to component aging. Resistors and capacitors can change value with age.

during 2001 or so there was a major manufacturer of caps that put out a HUGE lot of bad ones. They started to show up as short as a year after in hard use situations (computer mobo), but there probably are lots of those caps out in other applications also. (I think my car radio, a pioneer premiere 840, recently died due to a bad cap, possibly from this...)

IMO, the FCC will probably modify its technical requirements before the hardware takes a dump....

Cheers!

It depends on how well its maintained... I've got a Futaba that's 12 yrs old and it works fine. Had to change battery packs as the yrs went by of course. If u find a significant loss of air time, then its probably time to change. Don't wait for the batt to leak because by then, it would have taken out other things with it. Like the others, I think u should pay more attention to the switches, moving parts and the batt. Switches and terminals develop oxidation on them more quickly in humid conditions and this can lead to intermitent falls in voltage, so if possible, keep your electronics indoors in a dry place.

Oh, and assuming u do have a receiver that came along with your T6, have it checked thoroughly too. I used to race RC cars and I noticed that the receivers always fail after a couple of years. I attribute this to the rougher conditions that receivers undergo, such as dirt, dust, exhaust residue, vibrations and crashes.

I still have one of the first 5 channel pcm Futaba's made, and I use it to date. It must be at least 15 yrs. old. Oh by the way, I still have my first Kraft 4 ch. radio from about 29 + years ago and the last time I tried it, some 8 years ago, it did work.

I have six Kraft radios that range from 1974- 1978 that are still working. I have installed new batteries and have narrow banded them all. Two of them are the Phil Kraft Signature Series. Synthesized FM rcvrs and Tx modules.
