Old JEDIs - better quality than newer ones??
Posted: Sun Oct 16, 2005 2:28 pm
Hi folks.
I`m playing with JEDI-radios since many years. I have a number of them with a wide range of manufacturing dates. In my opinion the older ones (1997 and older) are of better quality.
Why?
Not only the well known display problems on radios made after 1998 - i still have to see one bad display an a, lets say, 1994 radio. There are some other annoyances on the newer models. The almost ever present noisy transmit (cracking, popping noises) - i mostly encounter this on newer radios. One exception are very used old radios. It seems wear and tear is making things worse (maybe this is the price, we have to pay
for the el cheapo screwless snap-together construction......).
On some of the newer radios i can hear steady buzzing sounds, when transmitting. It is not loud, but it is there. I sounds like an CTCSS-tone, but no CTCSS is programmed. I grabbed some older JEDIs (1993, `94 and `95) for comparision - nothing, completely quiet transmit.
Also on some of the newer radios i can hear a digital sounding humming noise, on the received signal. It is very faint, but my ears are working good. I was not able to find an older JEDI, which is doing the same.......
It seems, while assembling the (newer) JEDIs, they don´t bother to remove the white sticker (with the parts number on it) from the underside of the RF-board, even when its clearly visible that the edge of this sticker will be wedged in between PA-Module and frame, when the board is inserted. I don´t think, this plastic sticker works good as a heat conducting pad. So nobody has to wonder, if the PA is fried after a short time of use, due the lack of thermal contact to the frame. I had to remove the mentioned sticker on 8 radios (1998 and 1999)......
I know, this subject is almost beaten to death, but i`m very interested in your opinion and personal experiences about Jedi quality issues.
