Re: LA-1K AUTOBAND change issue.
开云体育Stephan ...I'm confused by your "its."? Can't figure out what the pronoun is referring to at times. "when it tunes for certain frequencies" ... the amplifier doesn't tune for certain frequencies; it is broad-banded and simply picks the appropriate band-pass circuits.? It is the transceiver and the ATU that tune for certain frequencies. "it sends power to the radio at the input rate" ... the amp doesn't send power to the radio, it is the radio that sends drive power to the amp. "it senses high SWR" ... I presume you mean the amp.? What ATU are you using? I have never used the amp on non-amateur frequencies and always assumed they were locked out.? But apparently there is enough overlap at the band edges to allow your operation on MARS frequencies.? I seem to recall (but could be wrong) that Palstar came up with a special firmware release for licensed MARS operators.? Send Mark Ward an email (engineering2@...) and see what he says. Lastly, it is interesting that you can manually punch-in a given band and all is well.? That might indicate something is wrong in the band-data line.? I'd check the cabling on both ends.? Those are very small conductors. 73, Kent K9ZTV On 4/22/2024 9:08 AM, Stephan Barott
