K9AY Vactrol contoller. Used to remotely change the termination resistance
of the K9AY loop for 80 or 160. |
 |
K9AY vactrol termination resistance and direction control |
 |
Current K9AY remote termination box with integrated vactrol and relays for 4
directions. |
 |
Array Solutions 6 PAK controller modified to support 12 V routing and
control. |
 |
6 PAK 7 band Autoselector. This box allows the FT1000MP to control the
TopTen which then drives these relays for the 6 Pak auto band selection. |
 |
This is the Amp Keying with TxEnable box. Non-QSK amps can use the built-in
delay to signal the FT1000MP when to transmit. |
 |
TopTen band decoder to ICE 419 bandpass filter interface cable. |
 |
Serial port keying cable for Writelog. The Rig Blaster keying and CW is
generated from this circuit. |
 |
This is the Array Solutions Stack Match control. The station uses these to
select any combination of 3 antennas on a band. No antennas are phased. |
 |
This circuitry is the central controller for locking out the switching of
antennas if a radio is transmitting on the band. |
 |
This is the circuitry added to each Stack Match. The antenna switching is
delayed until transmit is finished. |
 |
The station has 3 homebrew Stack Matches. This box acts as a power splitter
if more than one antenna is selected. |
 |
The 2 El 80M yagi relays and the 3 160M relays are controlled by this box. |
 |
This circuitry allows 2 of 4 radios to be selected for driving the antennas.
One or both radios may be on either table. |

above are interconnected in this diagram. |
