George, It takes 2 to 3 minutes depending on how fast you can take out 6 screws, disconnect 4 cables, connect the 1 to 4 cables from the QRP top and re-insert the 6 screws.
If you do not want to do that amount of effort or will be making the change often, it is easy to mount the KPA100 in an EC2 enclosure (or mount it with the KAT100-2. If you go that route, you will need a KIO2 option installed in the bse K2 - but there will only be 2 cables to remove from the back of the K2 to separate the external amp from the QRP K2. 73, Don W3FPR > -----Original Message----- > > Hi > After much hemming an hawing I just ordered the pa for the K2 > How hard is it to switch out tops for qrp and qro operation? > > Thanks > George > NE2I K2#4801 > -- No virus found in this outgoing message.
