I have both Amp & Tuner . In the beginning I had some (probably my fault) issues that were all solved by Palstar . I am so happy to buy from an American company that answers the telephone returns calls and backs the product up.?

Why are you considering this? Do you have issues with the expert??

Hi Joe,? I have a Flex 6600M driving the LA-1K and also the HF- Auto and I love operating the station. No towers are possible here in our sub-division so using wire antennas and running the LA-1K at about 600W peak seems to yield lots of arm chair copy QSOs.?
You won’t regret choosing Palstar, their products are very well engineered.?

I run a TS-590sg with the LA-1k, simply using a PTT connection only from the ACC connector.? I run a manual tuner and doublet. I set the menu for keying to mode 3 to add the 25ms delay.? Works well with VOX in that mode with a bit of delay on it so it's not ratcheting too much. I love the combo. LA-1k in standby, I use the? PFA key assigned to send Tune, click and send a 10W carrier tune. I then adjust my tuner and watch the SWR indicator on the LA-1k and adjust to 1.0, click the PF key to stop tuning, put the amp in oper?mode and go. The RF sensing is very handy and to get 1kW out (max I run, I want the linearity and clean output) takes roughly 40W in depending on band?+/- 5W or so. I also run it heavily on digi modes, PSK, Olivia, Thor rag chewing with long overs and it was a big motivator to go with the LA-1k.? The LDMOS amps work well at low input drive and low output. I run 2-5W in and 60-80W output on digi frequently. I set my audio drive and look for a 10A current indication on the LA-1k as a guide as duty cycle is all about temperature. I can run like this for hours and hours with no trouble.?? At 1kW on SSB it barely gets warm, the temp is higher on digi modes at 100W out to give you an idea of the duty cycle that digi modes have.
Very clean signals. I've been asked unsolicited several times running 1kW on SSB if I was running an Anan with pre-distortion due to how clean the signal is (it's not *that* clean, but it's very clean). On digi modes, nobody can tell I'm running the amp aside from signal strength.
I ran it on a very overextended 120 line at 700W out before I ran the 220V line for it. It even has protection for voltage sag so it would bypass itself before I was able to blow the breaker on 120 while testing a carrier into a dummy load.
For me, this was a big investment to talk myself into and I have no regrets.

I’d like to know how you get 1K on single side band with very little heat. On 80m i use 30 W drive and draw <34 Amps . SWR 1.1 to 1.2 . My temperature will get into the 60c with a long conversation and fast . The > 65c high fan does cool but of course it’s loud. BTW peak power 600 W or a bit more. Great amplifier for most hams but you must remember this amplifier cannot run 1 k very long Big difference between average power and peak power.?

I too sold my SPE 1.3k amp and bought the Palstar LA-1K.? The SPE was an excellent product, but could not cover many MARS frequencies.? The LA-1K with the MARS firmware works well from 2-30 MHz (excluding the CB segment around 27 MHz).
As I had an early LA-1K I recently sent it back to Palstar for updates ($99 plus shipping, amp was still under original warranty) which improved performance across the bands.

I had mine in for some work and they upgraded the LA-1K sw and now have a hard time hitting 60C? 50% duty cycle on 6 meters with 1KW out @ 1.1 SWR FT8. Mostly stays at 50C really cool.

Just to clarify, when I say 1kW, I mean really setting it for that, using a carrier and setting drive level to 1kW output.?
You don't set power out using your voice on SSB. Of course average power is lower. You still set using a carrier to whatever point the amplifier will operate below the threshold of compression. I believe the LA-1k is 1050W for that set point. SSB average power will be well below 1kW but the amp is set for 1kW output with a carrier as the input.
People taking an amp in this class and trying to see 1kW average power out on SSB are hammering the amps, driving them into compression, overheating them and why people believe LDMOS amps are "dirty".

This amp is STELLAR on 6 meters.? If you do the math, you'll see that it's running at around 70% efficient, that's why you don't get the heat up there.? LDMOS devices really "get in to their own" up in VHF and above. Dennis, N0SP

Very clean signals. I've been asked unsolicited several times running 1kW on SSB if I was running an Anan with pre-distortion due to how clean the signal is (it's not *that* clean, but it's very clean). On digi modes, nobody can tell I'm running the amp aside from signal strength.
I ran it on a very overextended 120 line at 700W out before I ran the 220V line for it. It even has protection for voltage sag so it would bypass itself before I was able to blow the breaker on 120 while testing a carrier into a dummy load.
For me, this was a big investment to talk myself into and I have no regrets. On Thu, May 7, 2020 at 10:55 AM Ernie Bauer via <ernie.bauer@...> wrote:

I am NCS for nationwide net and run 900 Watts for 2 plus hours without issue on 40/80 or 160, 35 to 40 input but run on 220 which is a must to run it that hard.? I've noticed people complain about fan noise, put on the cans and don't worry about it.? Until recently, when could you get? an amp putting out 1K in a 27 pound package?

Hobart What is your average temperature reading when you’re In a long conversation and you’re putting out 900 laws on the L a 1K meter. I’m assuming the high fan is always on at 900 W and a long conversation I was just curious what the temp was

60 to 70 degrees.? On long preambles say 4 or 5 minutes it will creep into the high 80s but you won't? have to worry, when it gets to 100 it will go to standby mode.? I've done it on purpose before.? No damage, it cools quickly if I see it going to above 85 I just cut input power back 5 or 10 watts, which drops me back to 800 or so, which doesn't affect signal that much.??

Hate to throw a damper on things, but have to comment. I also have an LA-1K tied to the HF-AUTO and in general have been happy with things. However lately some strange issues have started to crop up, the most serious is that whenever I try to run a digital mode (like fldigi) the amp keeps kicking off indicating SWR Bypass. (Only trying to put out 100W at this point.) I also have other issues with the SWR reading on the amp jumping up and down, and always being higher than what the HF-AUTO is indicating. I have made numerous attempts to get help from Palstar with no success. Emails go totally unanswered, and an attempt at a phone call did not get Paul, but rather another fellow, who indicated I was doing something wrong, must upgrade the firmware (which turned out to be a challenge as it must use Window$ and I had to try 3 machines before I found one that worked), etc. After all that I still have problems, but no more support. Also I am working with a very knowledgeable person at HRO who is also not able to get to anyone, and has other items besides mine on his plate with Palstar. Suffice it to say that this is very good equipment when it works right, but I suspect the god old days of reliable direct factory support are gone.

What is the antenna system, in full detail, that you are feeding with it?? What bands of operation?

Sorry to hear your having issues with digital. If its only during that mode then i would suspect its related somehow. I would try lowering your drive down to minimum then bring it up to where the issue starts. I use ft and output 1000w all day without issues with 35 watts drive. I would suspect a coax issue or rf issue at this moment in time. Try testing different bands and see if you can narrow it down. Also, are you using direct cable to radio or rf sensing? And i would suggest 220v wall socket.?
Its odd your not getting any support from them. I found them to be very responsive and great to talk to. Excellent customer support. Keep trying i guess. They have been very overloaded recently with the covid thing as alot of orders been comming in. I would be a bit patient but from my experience they have been very good and I just purchased mine a month ago.?
