[TenTec] Titan III

[HUGHESRO]

Hello. The qsk switching loudness can be reduced by using a hot glue gun to totally encapsulate the relay. It knocked the noise almost completely away. The glue will have no affect on any of the circuits. It works. W4IV  Roger mid TN

>Well, the Titan III is on the air... No problems encountered... Yes, I did trip the screen protection the first time, but got the hang of tuning up a screen grid AB1 linear almost immediately... It makes 1500 out at 52 watts of drive without even breaking a sweat ...
>  First time on many years to have an amp on the desk right next to the radio, so I am noticing the transformer hum on key down... Also, the relay switching in QSK is louder than expected - think I need to put a rubber pad under the amp to stop the desk top from acting like a sounding board.. 
>  What is almost inaudible is the fan... Almost can't hear the sucker and with the headphones on it is gone - this was unexpected...
>  The QSK is - well I don't know what to say -  the Orion QSK sounds the same whether the amp is on or not.  Making some contacts last night in the RAC and the practice session for the Stew Perry with N1MM Logger set at 22 wpm, I hear the tuner uppers, the vfo swooshes, and the terminally confused stumbling about, between the dits...  Other than hearing the amp keying versus when in standby, I could not hear any receiving difference in the Orion...
