I was just informed by the design engineer that it does NOT sense RF to transmit, so you need to provide a way to ground the KEY line input to the KXPA100 to transmit.
My apologies. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Ron D'Eau Claire Sent: Saturday, February 20, 2016 11:20 AM To: 'lstavenhagen'; [email protected] Subject: Re: [Elecraft] K3/K3S 10W models with KXPA100 It works very well with just about any QRP rig. Complete instructions for use with rigs other than the KX3 are included in the Owner's manual, available from the Elecraft web site here: http://www.elecraft.com/manual/E740199%20KXPA100%20Owner's%20Manual%20Rev%20 A5.pdf It will work well even with QRP rigs that do not have a key line to enable the amp. The amp will sense the presence of RF drive and switch to transmit automatically. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of lstavenhagen Sent: Saturday, February 20, 2016 6:25 AM To: [email protected] Subject: [Elecraft] K3/K3S 10W models with KXPA100 Hi all, May be a bit silly of a question, but how well does the KXPA 100 work with the K3 or K3S 10W model? Reason I ask is I now have 3 10W rigs (K3, K3S and a K2) and may be building a 4th soon (another K2/10). And in the very rare event when do go QRO, it would probably be cheaper to just get one 100W amp to use with them all than 4 100W amp modules for each. So my idea is a KXPA100 for my QRO ops with each one. So just curious how well this amp works with the K3 and K3S? I would imagine it'd be similar to using it with the K2 or ?
