8890 has been known in the past to be used by aviation traffic, although the allocated frequency would be 8891 if you use the 3KHz steps.

8834 is a RDARA frequency in this part of the world (Oceania).

also...

8834 is a HFDL frequency in South Africa.

Hermitage Flat, NSW.

Grid Square:  QF56dm.

Yaesu FT-1000D, Yaesu FT-2000D, ICOM IC-736 HF/50MHz, ICOM IC R75 & Tecsun S-2000 to 450 feet of wire, and a multi band vertical of dubious reliability.
