What is your 6 meter antenna?
Over the last 5 years, I 've made thousands of 6 meter QSO's around the US, Canada, Mexico and the Caribbean. Those were with either a 3 element or 5 element horizontal yagi at 25 feet.
Listen on 50.125 the SSB call frequency. (I've made zero 6 meter FM contacts - as in I've never even tried).
If you monitor 6 meters during daylight hours from late April to early July on many days there will be a ton of activity via Sporadic E.
Plus with an yagi as described above I can routinely talk locally out to about 100 miles.
A simple horizontal dipole or even a vertical can work just not as well as a horizontal yagi. An M2 or Cuschcraft 3 element is small and light enough that you can easily put it up and turn it with a small TV rotor.
The June VHF contest can be almost unlimited contacts - that is unless conditions happen to take a dump.
