I have mistakenly put 200 watts into my LA-1K several times. It just kicks out and gives the Overdrive message. The protection on this amp is very well done.

The only input issues I have heard of happening with the LA1K resulted from overdriving the Amp with a 200 watt radio like the 101mp. I would contact Palstar on Monday morning and get their opinion.

This morning while transmitting on 3.965mhz I noticed a HI SWR warning on my FTDX101MP. At the same time, the LA-1K displayed SWR=1.0 and the HF-Auto SWR = 1.04. I have discovered that the LA-1K RF Input has HI SWR while in "Operate" mode. In "Standby" mode
the RF input has normal antenna/Tuner SWR. The LA-1K will NOT amplify on 160, 80, 40 but WILL amplify on 20, 15, and 10. On 10m 10w results in 200w out. It appears something has happened to the LA-1K RF input. Any ideas what's going on???
