"Anyone mod the KAT500 for qrp? I'd like to use it at 1 to 100 watts."
I think you would need to define your expectations. A KAT500 needs about 20 W to perform a reliable full search tune but that power may be lower for an exciter that does not fold back with a mismatched load. The KAT500 needs than far less than 20 W to derive a frequency count from the RF input. (In one quick test I observed FC was set with 4 W on 30 m.) The KA500 needs no RF input at all to set the tuning solution manually using the Utility. The KAT500 needs no RF input to select a previously stored tuning solution if it is provided with the rig TX frequency by using the serial data port. So what do you hope will work at 1 W? An unmodified KAT500 will provide the same load matching at 1 W as with 1000 W but it will require manual tuning for each new frequency. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
