NOTE:
IMPORTANT
Keep in mind that the transceiver is only the exciter and should not be expected to generate high levels
of RF power, it should be expected, however, to generate a clean, perfect modulated wide-band audio
signal that can be later amplified with a class C, RF power amplifier to the desired level. It is highly
recommended to use dual final transceiver which allow for plenty of headroom and much cooler
operation.
For single final transceivers, such as the Cobra 29s & 25s, Galaxy DX-2547, DX-919, DX-959, etc.,
both RF driver and RF final must be modulated to achieve maximum modulation. Typically a .75
watt carrier with peaks of 10 watts pr300% modulation levels. This configuration puts a
greater load on the DC/DC converter as opposed to dual final transceivers where only the RF
driver is modulated.
For dual final transceivers (recommended), such as Galaxy DX-2527, DX- 98VHP, etc., only the
driver is modulated and the dual finals are fed +12 volts. This configuration offers plenty of
headroom and puts far less stress and less of a load on the DC/DC converter and allows for
higher RF output levels.
