Apache Labs ANAN-100/D - Important Operation Tips

Apache Labs ANAN-100/D
Important Operation tips
1. IMPORTANT: install the supplied 4 rubber feet on bottom of case for proper cooling
2. Do not short rear speaker jack
3. Do not cover rear or bottom ventilation holes. Proper air circulation throughout the ANAN-100/D is
necessary to prevent possible overheating and failure.
4. Calibrate power output to 100W using a 50 ohm Dummy Load. Operating SSB/CW at higher levels will
damage the radio.
5. Data/AM/FM and other continuous duty modes must be operated at 30W or less to remain within the
operational limits of the ANAN-100/D
6. Input voltage must be 13.8 +/- 5%, well regulated at higher amperages and proper POLARITY must be
observed.
7. DISCONNECT the Antenna during Thunderstorms or when not in use.
8. Please ensure that you select the correct model during software setup.
Heat Dissipation
Apache has stated that “The ANAN-10/100/100D use the [heavy duty] Aluminum extruded housing to dissipate
heat just like most military equipment, the 100W extruded section weighs around 2.2Kgs and has [a generous]
1515 sq cms of surface area”.
The design specifications for the ANAN-100 and ANAN-100D have been upgraded since the introduction of the
ANAN-10. The “Hermes” Transceiver board has a small Switching Mode Power supply on-board the PCB. The
SMPS provides a convenient and efficient way to drop from the 13.8vdc supply voltage to the 3.3vdc needed by
several of the Integrated Circuit chips.
In the new ANAN-100 and ANAN-100D, a more conventional voltage regulator was selected to minimize any
SMPS radio frequency noise (birdies), however this also created an additional heat load that needs to be
properly dissipated.
Ventilation holes in the bottom and back panel of the ANAN-100 and ANAN-100D must be clear of
obstructions so that the internal fan can circulate cooling air through the unit.
The ANAN-100 and ANAN-100D should not be operated at greater than 30% of their rated power when used for
extended duty cycles such as digital operation.
The Power Amplifier MOSFET transistors have characteristics that far exceed the needs of normal Transceiver
operation. They are quite rugged. However, other internal components such as the Filters, Integrated Circuits,
and some small SMT parts must also be considered when modes with high duty cycles are in use.
