Peter, Not practical - you will have to be satisfied with controlling the level of the drive to the linear.
In most cases, using ALC is not a good idea IMHO because it is normally set to be an indicator of gain compression which is another way of saying 'beginning to operate in a non-linear region' - so operating by depending on ALC is a recipe for creating distortion. As a parallel, you may want to consider why operators using PSK31 and other digital modes are instructed to opeate the equipment at a level below where ALC begins to operate to assure a good IMD figure - if ther is ALC action, distortion is occurring. The KPA100 uses a wattmeter at the output and communicates this information to the base K2 uP then uses that information to control the BFO injection in the K2 in order to control the power output. I would guess (but I don't know) that the 'to be announced' Elecraft linear will use a similar scheme rather than using the ALC method to achieve output power control and assure that the linear remains linear. 73, Don W3FPR > -----Original Message----- > > I am currently using my K2/100 to drive a linear amplifier (Yaesu Quadra). > I would like to use the ALC output voltage from the amplifier to > control the > output from my K2/100. > Has anyone managed to do this, and any recommendations? > Thanks > Peter > > ___________________ > Peter Bacon > www.g3zss.co.uk > www.oceanfone.com > > > > _______________________________________________ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.
