3. W4RM Station Location and Tower
The W4RM M2 Station is built on 10 acres in Nokesville, Va. (35 Miles SW of DC) and 1 air mile north Quantico Marine base on the west side of I95.
Currently, the Station has a single 110ft Rohn 55G tower using Phillystrain guy wires located 500ft from the house.
Antennas and placement:
125 ft 7ele 6M Force12 Beam
119ft 70ft 80M Force12 rotatable dipole with relay switching for CW and SSB
112ft 3ele 40M (MAG340N) Force12 Beam
104ft C31XR Tribander on a 1032D Tic-Ring rotor
72ft C31XR Tribander on a 1022D Tic-Ring Rotor
40ft C31XR Tribander fix mounted on EU

5. W4RM Station Tower and antennas
The C31XRs are connect to an Array Solutions Stack Match for stacking control
Second Feed Line Option allows split of stack
All Antennas are feed at the bottom of the tower into an Array Solutions Six Pack antenna controller
160M antenna is a single wire inverted L (80ft vertical) with 32 ground radials and 6000ft of wire
160M receive: A single 580ft NE beverage
Top rotor is an M2 Orion RC-2800P
The tower is connect to the shack by ft 7/8” hardline runs and one ½” 500 ft hardline run

10. W4RM Stations
The M2 Shack is designed with Two Run stations, One Multiplier Station, one Master computer station
The two run stations are identical and consist of the following equipment
Yaesu FT-1000MP
Alpha 99 Amplifier
Pentium Computer running Writelog
Six Pack antenna controller
MFJ-434 DVK
Top Ten Band Decoder
Dunestar 600 Band Pass Filter
2 CW paddles (right and left side)
LogiKey Keyer
Heil Proset

11. W4RM Stations The Mulipler station consists of the following equipment
Yaesu FT-920
Alpha 374A Amplifier
Pentium Computer running Writelog
Single ½” hardline run to crank-up tower (AB 577) with Force12 C4E
Top Ten Band Decoder
ICE Band Pass Filter
CW paddle, Heil Proset
The Master Computer is feed by a Comcast highspeed cable modem, router and 8 port switch
This master computer runs VE7CC and connects to K4JA packcluster, filters and feeds all three stations
This Master Computer also runs Writelog and acts as the master control point for monitoring band conditions for band changes and monitoring for new multipliers
