Re: [Flexradio] No ACL Output? What if the Linear requires an output

Gerry: Amplifier ALC's are OUTPUTS to the transceiver/transmitter. The voltage tells your transmitter/driver to turn down the wick. You may have meant this but your note does not read this way. The ALC inside the SDR-1000 on TX is just outstanding. Adjust the power and you will not be unh

Re: [Flexradio] No ACL Output? What if the Linear requires an output

UPDATE: I contacted W8JI, who is an expert on amps, and asked would the ALC have protected the amp for me when the coax connector failed. He said it would NOT have helped in my catastrophic situation. So apparently the ALC line is of limited usefulness, and probably can be ignored without putt

Re: [Flexradio] No ACL Output? What if the Linear requires an output

I don't think ALC would help on an antenna/feedline failure. Most amps have a tuned input that pretty much stays at a constant load for the exciter regardless of the load the output of the amp is looking at. An SWR alarm or auto shutdown on the keyline to the amp WOULD certainly help in case of h

Re: [Flexradio] No ACL Output? What if the Linear requires an output

I recently asked a similar question, Jerry, and was told that guys running the SDR-1000 just don't use hardware ALC. Many who spoke up said they never had any problem. I once blew up the output circuit of an Amertron AL-1200 because it had no way to shut down the exciter when the antenna circui

Re: [Flexradio] No ACL Output? What if the Linear requires an output

Gerald I suggest you look in this months archives and sort by subject. Look for this ( ALC for use with QRO external amp? ). There were quite a few replies on this exact subject already, just a few weeks back. Enjoy Duffy NA6MM ___ FlexRadio maili

[Flexradio] No ACL Output? What if the Linear requires an output

I'm considering linears from Ameritron (AL82) or an HF2000 from ROQ. Both have inputs from an ALC output from the transceiver. SDR1000 has none. Is there a safe way to provide the ALC output to properly run linears? Jerry -- next part -- An HTML attachment was scrubbed..
