Cross Banding Presentation Cross band repeating is a feature with some VHF-UHF dual banders that simply repeats what it receives on one band and automatically retransmit it on the other band. SIMPLEX
CROSSBAND Allows
two ht’s to communicate on different bands.You will need a cross-band
radio. (another HT or mobile with cross band)You do not set the HT’s you
are talking on in cross band.
Set one ht to a simplex vhf frequency and the other to a uhf simplex
frequency. Put both of the frequencies into the vhf-uhf dual banders and
set it to crossband.
Effectively extends the range of the ht’s on simplex. FULL
DUPLEX CROSSBAND TO A REPEATER Allows
an ht to have the range of your dual-bander. Set your ht to a suggested
SERA 440 cross band frequency. (example 440.775 for fixed station). Set
up your dual bander with a repeater frequency (example 145.15 -) and also
the 440 frequency that is in your ht (440.775).
Now set your dual bander to crossband and you have it. When you
key up your ht you will be transmitting on the 440 to the 145.15. You
will be receiving the 145.15 back to your ht on the 440 side.
You can also do this on a simplex frequency. HALF
DUPLEX CROSSBAND TO A REPEATER KEY-YOU
MUST HAVE AN HT CAPABLE OF DUAL RECEIVE AND BE ABLE TO HEAR THE REPEATER
CLEARLY ON YOUR Ht
Set
your ht to a sugested
SERA cross band frequency(example 440.775 for a fixed station)
and the repeater frequency 145.15.
You need to set the dual-band mobile with the input frequency on
the 2 meter side and the 440 frequency on the 440 side(to receive the
440 signal from you HT)Set your dual bander
mobile with the input frequency of the repeater
( example 144.55 for the 145.15
) and the 440.775 frequency in your ht). Now set your dual bander
mobile to cross band and you’re in buisness. Your HT must silence the
sub band when you transmit so you will not hear an echo. (Alinco DJ V5
does this in split operation) When you transmit on your ht (440.775) you
go to the input of the repeater. Then to hear the repeater you are listening
on the repeater output with your ht. What this does is limits the amount
of time that your dual band mobile is transmitting.
It only transmits when you transmit or when your dual band mobile
receives a signal on the input side of the machine. I
know this is a little confusing but this gives you something to build
on. SERA
