LINEAR AMPLIFIER INTERFACING
What should be "simple" is simply misunderstood
by many, if not most hams.
Most transceivers have a back-panel connection for keying a linear amplifier.
Most amplifiers have a back panel for connecting to the transceiver.
So why can't we just connect them together and expect them to work?
What all can go wrong if we get it wrong?
- You can blow up the keying circuit in the transceiver the first time you try to key the amp.
- You can burn the relay contacts in the Amp's T/R relay.
- You can damage the tube(s) or transistors in you Amplifier.
- You may be causing key klicks across the band when working CW.
- Any combination of the above.
In the past I have created two pages on related topics. Recently I created a page on CW AMP Sequencing. I have bundled all three pages together here under the common topic of AMP INTERFACING.
Even if you do not work CW, I suggest you read that page because it has a lot of useful information for learning about the differences in different models of linear amplifiers.
Here are the three pages:
