Shortly after 6m was released in the UK back in the mid 1980s I only had 1W to a simple wire dipole. This antenna was not very high and just strung from the gutter. I chanced on an aurora and managed to work some DX on 6m SSB, even with this set-up.
GB3RMK, the beacon way up in Scotland, was copied many times with this set-up on meteor pings on 6m. I used to leave the RX running and in just about every 15 minute period I would copy part or all of the callsign on CW. On 6m, auroras can be good.
On 10m QRP SSB I recall working the USA aided by auroras too.
