So, I got me a new CRE 8900. I like the radio and overall features. The local SSB geezers that I talk to, say it has best audio that they've ever heard out of my shack. I guess my TS-590, TS-870 and FT-ONE sound like crap.

I got my trusty straight key out, plugged it in the back and started calling CQ and was met this. :eek:

In the video below, my character speed is 18 WPM sending around 15 WPM. The break-in settings are whack. The carrier is delayed along with the sidetone. Sounds like I'm 14 again, studying for my novice. I am sending the word "test". If I key any faster, the sidetone is just one long beep.

In comparison, this is my TS-590's sidetone:

I talked to Univercom and they are going to discuss the issue with the factory and fix me up. They are on Christmas break until after the New Years. The radio allows you to change sidetone volume and frequency only. My nephew is borrowing my external keyer (he's in Texas) so I can't try my paddles.

Anybody else have a key they can plug in and check for this issue?

the orginal rci2900 was the same,they dropped it and went back to the drawing board and a month later fixed it and sent everyone a new rci2950,version 1 what was a good one...73 de n0zna
 
Got an email from one of the engineers in China. He recommended that a certain capacitor be removed to solve the side tone issue.

I'm just gonna send it to Key CB in Indiana and have them do it. That way, if it still acts up, he can deal with the factory boys.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
