K6NR Remote Station
More Phelan Photos
the K6NR remote amateur radio station which I control over the
Since December 2008 it has been based on an Elecraft K3 (previously a
Kenwood TS480SAT was deployed, and before that I used dialup modems and
a Kachine 505 transceiver). The K3 is connected to an Elecraft KPA500
amplifier. A Lantronix terminal server is used to control 7 RS232
It's a slow Internet
connection, so I use a telephone line for the audio in and out (the
real-time, no latency feedback is also very helpful in knowing the
current state of the radio).
The phone line also provides backup control capability to shut down or
cycle" radio and network equipment even if the network is down (via
controllers from Computer
Peripheral Systems, Inc).

Main tower: 55' US-Tower TX-455
crank-up, with a Force-12 EF-420 4 element 20 meter yagi at 60', and a
30/17/12 meter rotatable dipole at 65'.
The tower also supports a 80m/40m dipole, and the horizontal part of an
Inverted-L for 160 meters. pics

Second tower: A surplus AB-577 mast with a 5 element 15 meter
yagi at 45'.
Third tower: 38' of Rohn-25
and 10 foot mast with a 5 element 10 meter yagi at 48' and a
Cushcraft A3 tri-bander to provide a second antenna
on 20 through 10 meters. This is handy to quickly switch between two
directions while contesting.
40 Meter 4 Square: Vertical
based on the Comtek ACB-40
controller. Each homebrew 33' telescoping aluminum vertical has
about 60 some-odd radials.
80/160 Meter Vertical: 48'
high with 4 top-loading wires for 80 meters. In
parallel is a 130' "inverted L" wire for 160. There are 66 67' radials on the ground (I am in the
process of extending a subset to 130'). At the
base is a small relay box which will switch in a series capacitor to
tune the vertical for 80 meter SSB, or add in some loading for lower
resonance on 160 meters. An earlier 56' vertical did not survive the strong Phelan winds -
brother Malcolm put up a temporary
HF2V for me until I could build the current vertical.
For receiving I've crammed a double K9AY loop and two 300'
beverages on our 2.25 acre property. (Beverage feed point )
