CRT SS 9900

Post by StormShadow » 13 Oct 2015, 20:46

Hi all, I bought this 10 meter radio transceiver not to long ago on the auction site and before I return this radio back to the seller, I just want to make sure I'm not missing anything.

Well I got the radio and before I even set the thing up I had plugged it into my dummy load just to give it a quick test, so the radio radio powers up ok I turn down the power before I key the mic, so I test it on 2 watts and things are fine, past 2 watts it will beep and display SWR HI and then the TX will cut out which is really annoying me. How can the SWR be high if its in a dummy load? There is nothing wrong with the dummy load. I checked the patch leads from the radio to the dummy load I even tested the power supply to make sure it was delivering enough current and everything is fine. I have no problem testing other radio's but the CRT SS 9900 this SWR HI is giving me this stupid problem. Has anybody else had this issue? is there something I need to press or program on the radio? or is the radio faulty junk?

Well I turned off the useless high SWR protection feature on the radio, the SWR reads 0.1 on the radio itself and then again on the second SWR meter its reads nice and low right up to about 30 watts. So I don't know what that "High SWR Protection" business is all about. Trust me to get a radio with a fault on it. :shock: :roll:

Oh I forgot to say its plugged into the antenna now and not the dummy load.

I have the same radio and i thought i had a problem with it more or less the same as yours using a dummy load it kept comming up high swr but on a antenna it was ok when looking at the dummy load it was only made to take 25 watts when the radio was doing 70 watts i do not know if that makes any differance but as i said ok swr readings on a antenna (1.5--1.8) ??
