LA-1K Frequency display
Just received my new LA-1K. Love the AMP.? Just wondering if anyone else has
a problem with the AMP frequency display not displaying the same frequency as the transceiver? Not a big deal but thought I would ask this new group. I figure there is a way to adjust that buy don't want to open up the amp. Hayes Copeland |

Re: LA-1K Frequency display
Mark in Palstar Engineering is submitting this response: "The LA-1K's readout may be different than the radio display frequency because: Radios show the "carrier" frequency in USB or LSB. On side band, the carrier is not transmitted, so only the upper or lower side band frequencies will be present. These will be higher on USB and lower on LSB than the "carrier" frequency. Example: If you transmit a 1kHz tone on USB (radio at 14.250), the output will be 14.251 14.250 + .001 (upper side band) = 14.251 on LSB it would be 14.249. Transmitting in AM should show the actual carrier frequency. |
New amp concerns
Hello,
Just picked up a new LA-1K to go with my HF-Auto. My first concern is that I think I have a sticky relay, I'm getting an intermittent transmit delay, and the display on the Amp says "TX Wait" anyone one else experience this ? The other is which power meter is more accurate ? the bar meter on the amp or the numerical on the HF-Auto because they both read different. Thanks? |

开云体育I think the wait signal comes up when you close the PTT switch but have not sent power down the coax. So if you key on SSB and don’t talk, you will see wait. ? The bar graph on my LA-1k is no where close to accurate.? My HF-Auto matches my LP-100 pretty close but the L1-1K does not. ? Rich ? From: la1k@groups.io <la1k@groups.io> On Behalf Of BJN644 ?

Power meter
Gene Caldwell
an earlier poster mentioned that the power meter on the LA-1K was inaccurate and, I guess by extension, the SWR meter as well.? At the present time I do not have a separate meter.
Can I rely on the LA-1K meter at all or do I need to bite the bullet and get a LP-100a which is not in the budget right now? :) Thanks, Gene K3GC |
Re: Power meter

开云体育The way the meter was designed it would be hard to get a good power reading anyway.?? There are no marks so you are only guessing that 600 watts is in the middle of the “600”.? Best guess is when my amp is doing 600 watts its really doing about 550.? I have a LP-100 coupler about 3’ from the output connection on the amp and trust it more than I do the amp readings. ? I don’t even know if the circuitry in the LA-1K allows an accurate reading?? If it did, it would be nice to replace the large “POWER-WATTS” on the top with an actual digital value. ? Although the amp works pretty well, the display could use some work in my opinion.?

开云体育I have not really put the coals to it because I have some RG8-x in the shack I want to replace before I do.? However I ran it up to 1KW very very briefly. ?
