approximately 30 ft long
your mf-hf with antenna breaks off and is carried away in a storm what would you do to regain
operation on mf-hf frequencies correct answers rig a wire antenna approximately 35 to 40 ft long

correct answers examine the received data directory or the printer to recover the information
a DSC distress call is received by your vessel and your transceiver frequency display reads:
transmit equal 4207.5 kilohertz and receive equals 4207.5 kilohertz with j3e emission. what
information can you infer from this correct answers the DSC call requested voice on 4207.5
kilohertz simplex but the requested alternate frequency is improper
,what are the potential dangers of automatic transceiver switching in response to a DSC call
correct answers the transceiver maybe switched out of the Marine bands or the frequency may
not match the requested priority or emission
which of these would not be a bad outcome of an urgency DSC call to all vessels specifying an
alternate Telex frequency and emission that cause your transceiver to automatically switch
correct answers the DSC controller decoded the contents of the DSC call and the requested
frequency is on the DUS table placard in the j2b emission
an incoming distress priority 16 MHz DSC call requesting j3e emission might automatically
switch to what frequency correct answers 16420.0 kilohertz
an incoming DSC distress alert on 8414.5 kilohertz will have what result correct answers all of
these answers would typically occur
what is the normal voltage of a single lead acid battery cell correct answers 2.1 volts
what is the normal specific gravity of a fully charged lead acid battery cell and what device is
used to measure the electrolytes of a lead acid battery correct answers 1.280 hydrometer
what is a gel cell battery and how is it maintained and cared for correct answers gel cell batteries
are typically sealed special charging rates and voltages may be required
what will cause an individual battery cell to reverse polarity correct answers when discharging
the battery string if a cell becomes weaker than the remaining cells the discharge current will
effectively charge the weaker cells in reverse polarity
what is the effect of temperature on the specific gravity of lead acid batteries correct answers
higher temperature results in lower specific gravity reading
,what would be an indication of a malfunction on a GMD SS station with a 24 VDC battery
system correct answers a constant 30 volt reading on the GMD SS console voltmeter
a ship has been communicating effectively on 16 MHz during daylight hours with a shore station
at a distance of 3,500 MI towards late afternoon and evening what effect would be noticed
correct answers communications should gradually deteriorate and become impossible on this
frequency at night
stupid anchor has been communicating with a shore station approximately 200 miles distance on
a frequency in the four megahertz band through mid-morning towards late afternoon and evening
what effect should be noticed correct answers communication should gradually improve and
peak at night and early morning
at midday in the summer what would be the best choice in attempting to communicate using
SITOR (NBDP) with a shore station 1800 miles distant correct answers higher HF bands
at midnight what would be the best choice in attempting to communicate using SITOR (NBDP)
with a shore station some 800 mi distant correct answers HF bands
at midday what would be the best choice in attempting to communicate with a shore station some
75 mi distant correct answers mf
how can a gmdss operator determine the best frequency band to choose for a SITOR (NBDP)
transmission to a shore station correct answers by listening to shore station free signals and shoes
the band with the strongest signal
the "short rules" of propagation necessary to select the appropriate frequency band correct
answers shorter distance = lower frequency, daytime = higher frequency
what would be the most appropriate HF bands for communicating from San Francisco to Taiwan
or the Philippines correct answers 16 or 22 megahertz when daylight at each end and 8
megahertz when dark at each end
, gmdss operator should routinely focus on factors affecting propagation in what priority correct
answers distance and time of day, seasonal variations, sunspot cycle, solar flare alerts
which statement concerning frequency band selection and propagation most corresponds with
standard practice correct answers propagation rules of thumb are usually sufficient for routine
operation
to ensure effective HF communications gmdss operators should correct answers Employ the
short rules of propagation selection or rely on previous successful communications as a guide.
if the vessel is within range of Navtex broadcast and both the inmarsat-c and the navtex receiver
are inoperative the GM DSS operator should correct answers select 518 kilohertz FEC telex on
the mf/hf console to receive MSI
if the vessel is beyond range of navtex broadcast and the inmarsat c system fails the GM DSS
operator must correct answers select an HF MSI frequency and FEC t e l e x mode to receive m s
i
if the vessel is experiencing atmospheric interference with navtech broadcasts especially in the
tropics the GM DSS operator should correct answers select one of the eight HF MSI frequencies
and set up the transceiver in FEC Telex mode
why must the gmdss operator be able to set up FEC and arq modes and differentiate between
them correct answers the proper mode must be selected for follow on Telex communications in a
distress situation and for the reception of HF MSI
bfec SITOR (NBDP) transmissions might be used to correct answers send and receive distress
Telex communications and receive HF MSI or navtech
FEC SITOR (NBDP) transmissions are normally used to correct answers receive HF MSI and
navtech
