Thank you Chuck your absolutely correct, thanks for keeping it honest.

Michael:

Keep in mind that people don't often just sign up to this mail group and submit a post saying that it's working fine today, but if there's a problem they would be more likely to join the group and ask for help.

So, I'll break that trend and say that my LA-1K and HF-AUTO are working fine today and that from what I've seen this is good equipment and the people at Palstar are always willing to help if you have a problem.

I joined this forum to assist me with making a decision about if I should purchase the LA-1K. Would it be correct of me to be a little apprehensive due to the number of comments regarding the trouble operators have experienced with their LA-1K. This unit has been out for some time.

Thank you for your feedback.

My week old amp went back to the white screen. Could not get it to boot up. Sent it back to Palstar received it back Saturday. Had a small metal particle shorting 2 pins. Works fine now and fast service.

Mine does same thing.

all my equipment are well grounded and I still get the occasional WSOD - white screen of death. The only method that works for me is to power up LA-1K at first and then all the other radios and Tuner! - I have no idea if that makes any sense, but it does work for me!

I have no idea why, but if I am using ANT2, and switch bands, and switch antennas to ANT1, when I go to transmit, the LA-1K goes back to ANT2.? Then I can switch it again to ANT1, and it stays there.
I have no idea why it isnt staying on the ANT I have selected when I key up...but it apparently switches back to the last ANT position that was used for SSB.

Everything was grounded. Now the amp and transceiver are connected together. Might be a fluke but it's working fine now.

My week old LA-1k started just booting up to a white screen. Tried plugging a cable into the Yaesu jack like suggested on here. It did nothing.? Ended up dissconnecting the keying line. It boots up then. Talked to Mark at Palstar. He had me run a ground wire from the Amp to the transciever. So far it has worked. Hope it keeps working.

I wish we had a small box like the HF-AUTO-R to control the amp features...

as there is no official support on this and the TRX manager software is rather difficult, after the warranty period is over, I have the following idea to try.

use a solenoid push type actuator to push a stylus pen which can toggle between standby and operate mode.

of course the solenoid push force has to be gentle enough not to damage the touch screen and some sort of mounting is needed to properly align it to the OPR/STBY portion of the screen.?





see this for the solenoid linear action...

Thanks.? First firmware update for me.? Didnt want to brick it.

Is the firmware the text file in the zip?? Normally firmware is labeled .bin

Hi Steve - there was a customer that asked a similar question, the answer from one of the engineers might help you or others so I'm posting it here:? ?

ALC is NOT required and should ONLY be used on SSB.

It’s kind of a leftover from when transceivers had poor output power regulation.

?

Most modern rigs need only -1.5V ?to -3V for ALC voltage to start reducing their power output.

?

ALC setting is highly dependent on which transceiver is being used.

Setup is a simple two-step process.

?

I suggest, as outlined in the LA-1K owner’s manual FIRST to set drive level (with ALC set for minimum or disconnected on LA-1K).

Drive would be set on CW for desired output (Example 800W)

?

After setting for desired output power, ?switch to SSB mode.

While speaking in microphone, slowly advance the ALC setting on the LA-1K until PEAK RF power output just slightly drops.

This is the desired setting.? Any higher will degrade the transmit quality.

?

Alternatively, this may be adjusted by looking for a small INCREASE in the transceiver’s ALC meter reading.

?

These settings should be checked or readjusted when switching bands.

Tnxs for the info VU2TG. Ordered it thru HRO.

Interesting...

So it could be the LA-1K was not reliably detecting the frequency? That might cause a problem also.

Bill:

I am using a Polyphaser. They work fine if they are selected for the proper frequency and power range. There also needs to be consideration for the amount of SWR that is expected on the line since higher SWR translates to higher voltage peaks.

The reason some protectors don't have problems is that they may not be sensitive enough to protect at the needed level. As with many things, it's a trade-off that you make when you select one. There's other protector manufacturers that do a great job and lots that are useless. Stay away from any that can't give you proper specifications.

That of course doesn't mean that a properly selected protector can't be having problems either from previous hits, moisture, or otherwise. I need to pull mine and service it. You can get parts for the Polyphasers.
