K3 and SPE Expert AMP

Is anyone using the K3 with the SPE Expert amplifier? if so how do
they integrate the two with computer control?

Re: K3 and SPE Expert AMP

Richard,

The K3 emulates a Yaesu radio's band data output. The SPE can use this
information to switch bands.

Richard, If you go to Yahoo groups, there a group for the Elecraft K3 and one for the Expert Amp. I believe in both of them in the files section there is a drawing for configuring the cabling for the K3 the Expert Amp and your computer. From what I see in the K3's manual and the Expert Amp manual it looks pretty good. I am in the process of obtaining the parts to build one now.

Hope this helps.

Re: K3 and SPE Expert AMP

Gentelmen,
I am considering the Expert amplifier because of instant turnon, smaller size and reduced weight. Does the Expert amplifier require a tie in to the transceiver other than RF input and key out to determine which frequency to tune to? The ACOM 2000A does this automatically sensing the frequency from the RF Input and there is not need for an interveing PC. Is it the case that the Expert amplifier needs a separate input defining the operating frequency and band?

Re: K3 and SPE Expert AMP

The SPE amp will "RF Sense" like the Acom 2000A to switch bands.

It also has provision to be driven by the Yaesu format band data from the K3
but you do not need to do that - if you don't want.

Hi gentlemen,

Ideally you should pass band data from K3 to the Expert amplifier. But if
you do not the amplifier will still be able to sense the transmit frequency
- but you have to transmit (just a dot or two). Just changing frequency at
the K3 will not change the Expert amplifier to the correct band.

Re: K3 and SPE Expert AMP

In reply to this post by Doug Turnbull

Doug,

If you already have remote antenna switching, I would use the K3 bcd data to do the antenna switching prior to the amplifier rf sensing the band. this would prevent transmitting into a wrong antenna...unless, of course, you plan on using the built in antenna switch of the SPE then I would rely on the K3 band data provided to the amp rather than rf sensing.

73 and good luck

In reply to this post by Doug Turnbull

Expert can sense the frequency from RF input (like ACOM2000) or get
frequency information from the radio via RS232. It is your choice how you
configure that. I think one can download the Expert manual from the site and
read it all there.
