Specifications

Note: The last photo shows a highly modified ARI-500 that is the subject of another
article.
In order to use this interface unit, strap the ARI-500 as though the ALS-500RC is being
used. Unlike the ALS-500RC however, this interface unit does not disable the ARI-500
auto-reset, nor does it load the ALS-600 RF power meter. Now I can mount the ALS-600
out of the way and still monitor TX and O/L status. And I can easily switch between
OPERATE and STANDBY so I can check transceiver drive or switch between barefoot
and full-power operation.
