| The
analogic frequency readout of the original ATLAS-210 is very
simple .Infortunatly nowadays people are more accustomed to digital
frequency display .To put such an equipment this is very simple
on the ATLAS-210 due to the presence in the rear of the
transceiver of a socket where the signal coming out
of the VFO is available .As ATLAS-210 is a single
conversion transceiver , the transmission frequency is
equal to the VFO frequency plus or minus the intermediate
frequency (5522 khz) . Several kits are available through the internet
to
build a digital frequency meter at a very reasonnable cost (around 60
$) .The one that we recommended is the one supply by
AADE.COM which can be built in a matter of 2 or 3 hours .It
consists of a microcontroller and a 16 caracters LCD plus resistors ,
regulator..., .The frequency resolution is 10 hz and does not generate
any birdies on the ham band .You do not need any
special equipment to tune the circuit so as to have the exact frequency
readings .As you will see AADE.COM have various
digital meter for the various transceivers still alive in the ham
market .For ATLAS-210 choose the DF1D .You will have to
choose between put the module directly in the transceiver or put it in
a separate box .The power supply is taken on the general power supply
of the transceiver |
