Re: Antenna selection
I would suggest that the type acceptance requirement for the amp would MANDATE that it not be usable on 60 meters since the maximum allowable transmit power on that band is 50 watts ERP.? ?Just like the 27mhz lockout is required.? Using this amp on 60 meters would be illegal.

Re: Antenna selection
Please find below an excerpt (highlighted in bold/italic text for clarity) from Page 5 of the LA-1K Technical Manual for your consideration, Steve.
BAND SELECT To switch bands (160M, 80M, 40M, 20M-15M, 12M/10M, 6M) press the BAND button on the touch-screen display then select the desired band. As can be seen above, 60M isn't a band available on the "LA-1K RF SENSING 1000W DUAL HF LDMOS AMPLIFIER" currently available from Palstar. Thought you might have, for example, modified the firmware on your LA-1K amp to allow it to work on the 60-Meter band. Oh btw, 6M (labeled 50MHz by some manufacturers) is an available band on the LA-1K, so I am not sure why Palstar would exclude 6M in naming the LA-1K amp because HF doesn't cover 6M. 73, Ray KJ5MI |

When I am on 60m and have antenna 1 selected I am transmitting on antenna 2, if I select antenna 2 it works properly. Has anyone experienced this? This is only happening on 60m.As seen near the bottom of this page "Frequency Range: 1.8 to 54 MHz" is listed as part of the LA-1K Specifications.? But, how do you trick your LA-1K to work on the 60-Meter band, Steve? 73, Ray KJ5MI |

I think I can speak for a number of this forum's members. You aren't happy with? your LA-1K, you didn't like "Mighty Fine Junk." Now, moving on to Elecraft, I would bet that in a few months, you will be picking it apart!

Barry, You are not doing the same thing there with your LA-1K as I am with my new Elecraft.? Same thing = using a 15M monobander on Ant 2.? Using a 6M monobander on Ant 2 is okay with the LA-1K since 6M is a band-select choice all by itself.? Your LA-1K won't allow you to use a 15M monobander on Ant 2 and a 20M monobander on Ant 1, the way I can with my Elecraft KPA1500.? Bottom line: If you are still of the same opinion "So your remarks of the LA1K not allowing its owners to do the same is untrue." then you are reinventing the truth, my friend. Btw, I had a telephone conversation with Mark Ward (Palstar technician) on their inferior design implementation in grouping 20M-15M as one band-select choice, shortly after I received my LA-1K.? Mr. Ward thought at the time surely the LA-1K would allow a 20M monobander on Ant 1 and a 15M monobander on Ant 2, if I wasn't using RF sensing.? So Mark tried doing it without RF sensing and was unsuccessful in making the LA-1K to permit a 20M monobander on Ant 1 and a 15M monobander on Ant 2.? Case closed! In terms of you saying "A simple serial cable is all I needed for auto band switching with my LA1K."? So, is your LA-1K also acquiring in real time the exact VFO frequency in the selected band of your transceiver, without ever transmitting?? I don't think so, Barry. In terms of you saying "Sounds to me your upset and decided to slam the LA1k build and sales pitch your KPA1500 and paid a lot more for it than the LA1K."? Please take time to go over my 5-Apr-2023 post /g/la1k/message/1182 in which I pointed out the KPA1500 is a bargain comparing with the USD $3,695.95 LA-1K (just 1kW) and the USD $1,695.00 HF-AUTO combined; totaling USD $5,390.95. So truth be told! 73, Ray KJ5MI |

I too love my LA1K. When shopping I contacted Elecraft. I called them. They didn't answer so I left a message. No response. I emailed them. No response. I called Palstar and talked to Eva. She took a freshly build unit and sent it. I can't recommend them enough.

Ray, ? All of these issues you stated that the LA1K cannot do is incorrect. I am doing the same thing here with my LA1K as you are with your new Elecraft. ? Only difference is im using a 6m monobander on Ant 2 and not a 15m monobander. A simple serial cable is all I needed for auto band switching with my LA1K. ?

If I had the money, I would also buy a KPA1500 but I don’t, but doesn’t give reason to slam the build quality of the LA1K. I don’t care either way but think your complaints are way out of line here over a simple light in a switch. ? I love my LA1K and enjoy it as it does exactly what its made to do. Nothing more.

Re: Inferior Design Implementation
Hi Ron,
Hope you had a nice weekend... I spent most afternoon last Friday rearranging things to welcome my brand new Elecraft KPA1500 into the KJ5MI family of ham gears.? After a weekend of fun getting to know the many available user-configurable KPA1500 features (e.g. Tech Mode) and doing real-world tests and evaluations, I even found time to update my QRZ page: yesterday. The KPA1500 allows me to work 20M/15M bands with a 20M monobander and a 15M monobander connected to the Elecraft "Ant 1" and "Ant 2" ports, respectively.? In contrast, the LA-1K simply wouldn't allow its owners to do the same (known to me for months!) due to Palstar's inferior design implementation in grouping 20M-15M as one band-select choice. What's more... All I needed is a simple serial cable for my Yaesu FTDX101D to put the KPA1500 in "Enhanced Mode" allowing for automated band switching, antenna selection and ATU memory setting recall in real time by acquiring the exact VFO frequency in the selected band of the FTDX101D, before ever keying up the transceiver. I am keeping my LA-1K (bought direct from Palstar earlier this year) with the defective power switch in place, and pairing it with a MFJ (affectionately called Mighty Fine Junk) ATU to be driven by my trusty old fashioned Yaesu FT-857D by way of RF sensing. Oh btw, I have received the 2nd replacement LA-1K power switch from Palstar last Thursday.? I will switch out the power switch when I decide to get rid of my LA-1K. 73, Ray KJ5MI |
