[Repeater-Builder] update:Can I lose a cavity using an amp and an atenuator?

[Ian Ashford]

I'd better clarify my question,   The cavity I would remove is in the Tx arm. Its job would have been to remove noise from the transmitter at the receive frequency.   By replacing this with a 120watt amp and an attenuator to return to the original 25w, I was hoping to have improved the signal to noise ratio of the transmitter.   (I think a class C amplifier removes AM sidebands and because it is in gain compression it  attenuates spurs/noise at  +and- 600khz )   Maybe the scale of this cleanup would small compared to the large (40dB) noise notch I have removed...   If anybody is interested I'll report my results in a couple of weeks   Ian G8PWE   ----- Original Message ----- From: Ian Ashford To: Repeater-Builder@yahoogroups.com Sent: Thursday, November 06, 2003 10:21 PM Subject: [Repeater-Builder] Can I lose a cavity using an amp and an attenuator? At the moment I am testing a  2m 4 can duplexer with a 25 watt transmitter and all is fine.   I wish to remove one of the cans in the duplexer and use it for another purpose (part of another duplexer actually)   If I lose a can from the tx arm can I "clean up" the transmitter with (say) a 120w solidstate amp followed by a high power 6dB pad?   has anybody in the group tried this?   Ian G8PWE     Your use of Yahoo!
