SATELLITE STATUS: 2023 Update
Not QRV for satellite (at present) but IC9700 was purchased to replace the FT-736R. It provides
144, 432, and 1296 operation with satellite mode. A 2-inch pipe mount will be placed in back of new
hamshack for installlation of az-el rotator and satellite antennas in the future. Switching preamps
for 2m and 70cm to be installed at the antenna. No amplfiers needed for transmit.
SATELLITE STATUS: 2021 Update
Installation of VHF/UHF Az-El system hit a snag with inoperable Yaesu B5400 rotator; purchase of an used B5500 also not functional
so both were shipped for repair by a friend (KL7H); unknown estimate for repair.
So I replaced antennas with my ARX-270 dual-band high-gain vertical mounted on a 20-foot mast for the interim. Unknown performance
for cross-band duplex with Leo Sats, but am using a Comet diplexer with my new IC-9700 (which is satellite capable for 144/432/1296).
I still have a 1268 loop-yagi and DEMI 144/1268 15w transmitting convertor for use on L-band uplink and Drake 2401 downconverter and
patch antenna for S-band. They are not currently installed.
SATELLITE STATUS: Under Re-contruction - Fall 2019
Ten foot Rohn-25g tower has been moved to new location at east end of new dog kennel on hinge plate
for laying antennas over for maintenance. Rope and pulley attached to garage rafter provide raising
and lowering.
LMR-400 cables, two rotator cables, and control cable for future relays/preamp were run summer 2019.
After testing of rotator, 2m and 70cm antennas will be attached. Mode-S patch antenna also installed
but without cabling.
SATELLITE STATION CONFIGURATION:

Power Output = 5-30W
MODE-U (435-MHz):
High Gain Antenna: M2 436CP26 X-Yagi (RHCP)
Receiver: 0.5-dBNF Preamp
Power Output = 5-30w
MODE-L (1268-MHZ):
Antennas: 45-Element Loop-Yagi (Removed)
Transmitter: DEMI 144/1268 Tx-Converter (Removed)
Power Output = 3-15W
MODE-S (2401-MHz):
Antenna (LEO): 8 dBic RHCP patch antenna, L-Com HG2409PCR-NF
LNA: DB6NT 0.8-dBNF (Currently not installed)
Receiving converters: Drake#1 2401/123-MHz and Drake#2 2401/435-MHz (Not currently installed)
Auto-tracking of the B5400 to be provide by the LVB Tracker.
FALL 2009 Update:
High winds 12/14-15 collapsed the mast. Antennas not hurt, but will not be repaired until spring 2011.
April 2011 Update:
NA1SS Achieves WAS - January 21, 2006:
At 2345 utc on Jan. 21, 2006 I worked Bill McArthur
on the International Space Station to give him his final
state (Alaska) for WAS from space. I operated on
144.490/145.800 MHz with 50w to my 9-dB gain
vertical (ARX-270) for easy Q-5 signals with Bill.
I kept my contact short so that Dale, KL7XJ, could work
Bill on the same pass. Here are images of the NA1SS QSL:
SUIT-SAT OBSERVATION - February 4, 2006:
Suit-sat was tracked on pass 10 (coincides with ISS pass 41,227) with AOS at 1509utc
at azimuth=211. Tuning 145.990 + or - 2KHz nothing was heard until az=178, el=6
where tones sounding like sstv were briefly heard. Tuning 145.989-145.988 produced
FM quieting and brief moments of voice. They faded in/out too short for any recognision
of text. This continued until az=121. el=5.7 where no more was heard.
Closest range was 1354 km. Overhead passes at closer range, which do not occur here,
might produce more recoverable audio.
Equipment used (EME Station): 4xM2 2M-XPOL-20 yagis (Vert-pol), mgf-1801 preamp
(0.15 dBNF), 130-feet of LMR-400, 3SK48 line amp (1.0 dBNF) before FT-847 in FM mode.
