Re: SWR High SSB ONLY - When Using LA-1K Amp


 

I have an LA-1K? and have no issues.? ?I have an HF-Auto Tuner.
I read some were using?a band data cable.? Not needed it is an RF Sensing amp.
Other obvious question or comment.? You must connect a PTT cable to the amp.
If your tuner is reading correctly with the amp on standby
there should not be an issue.? If your tuner remains constant,again there
shouldn't be an issue.? ?Run on a 220, I run the amp full out, usually
45 input from my ftDX5000 will give me 1050 to 1100, but usually run at
35 to 40 gives me 900,also depends on band, you might want to run
more input to maintain your amp output.? Don't run enough CW to be of help,
but if your amp is shutting down because of swr, by all means
contact Palstar.? The temperature?your amp is more important
if it is running over 85 degrees C it is time to think about backing
off on input power.? 220VDC is the only way to? go unless you only want
650 out.? This has been my experience.? Hope this
helps some.

I can not use SSB currently,? few words in - LA-1K went in to Bypass SWR just about 30 watts drives.? Attached video clip, at 5 sec in the SWR went up to 9.8 real quick and that tripped the Bypass SWR.? Antenna was tuned with AT2K down to about 1.0 - 1.1.?

?I am not really sure what is happening here.? I guess I will have to wait to talk to someone at Palstar Monday.? I do not even know if any one at Palstar monitoring this user group.
