I seldom use the thing and I cannot say for sure what summit I lost it on, but if anyone doing:
W7A/PE-029 (Agua Caliente Hill)
or
W7A/PE-004 (Oracle Ridge)
finds the rubber ducky for an 817ND, it’s likely mine.
I use a directional antenna for 2M, but I keep that one in the box so I can listen to 2M when I pack and unpack.
If you find it (long shot) let me know.
