[Elecraft] KREF-EXT Option

[Geoffrey Downs]

Dear Jan,

Many thanks for your interesting suggestions re the Analog device. I was
asking about the Elecraft option on behalf of a friend in the Netherlands
who is thinking of buying a K3 but if there is no word from Elecraft on the
subject I will pass your thoughts on to him. I do not know the answer to the
question in your last sentence.

73 to all
