Background:
HH2AA is one of 22 current pay-to-use stations made available for remote
operation by Remote Ham Radio (www.remotehamradio.com) to members. It is unique
in that it is the only station that may not be operated using your own callsign
and the fact that all proceeds from station rentals are returned to the people
of Haiti through donations to the Haiti Air Ambulance Service organization.
Refer to the HH2AA QRZ page at https://www.qrz.com/db/hh2aa for more
information.
It is an ideal site to operate in order to get the thrill of operating a DX
station from the convenience of your home!
Setup:
Hardware:
HP Envy x360 Windows 10 laptop, Elecraft K3/0 Mini and USB connecting cable.
USB to RS-232 cable and connections needed to provide WSJT-X with a PTT
connection to the K3/0 Mini.
Software:
Name Provides
Chrome Browser access to the Remote Ham Radio (RHR) Universal Console
RHR App interface between Universal Console, K3/0 Mini and remote site
DX Commander CAT control needed to use WSJT-X plit features
WSJT-X FT8 processing and broadcasts contacts to N1MM Logger+
N1MM Logger+ desirable logging, analysis and file export features
Critique of remote FT8 operation in ARRL RTTY Roundup mode:
Operation with the above setup was flawless, except that multiple responses were
required in order to obtain an RR73 response form a caller, which logs the
contact. It appears that the latency of remote control results in timing issues
that prevent the caller’s WSJT-X software from “seeing” the responses
until some type of synchronization occurs. The unfortunate result is that each
additional response adds 30 seconds to the QSO. I operated for about 13 hours
for an average of only about 21 contacts per hour.
Other observations:
The suggested FT8 frequencies were as follows:
Band (Meters) FT8 Frequencies (MHz)
80 3.590 – 3.600
40 7.080 – 7.100
20 14.130 – 14.150
15 21.130 – 21.150
10 28.160 – 28.200
All FT8 operation observed in the waterfall was within 3.5 KHz of the bottom
end.
It was suggested that run stations should select integral multiples of 200 Hz as
their audio transmit frequencies and check the TX EVEN/1ST box. It appeared
that most run stations complied with this suggestion.
It was also suggested that search and-pounce (S+P) stations call at frequencies
0, 60, or 120 Hz above the run frequency. It appeared that only a few callers
complied with this suggestion.
In spite of the apparent remote control issue that I had, I am satisfied that I
did the best I could in the time I spent operating in the contest. It still got
the adrenaline flowing!
73, John W2HUV
