I am a new licensee.... is it best to call CQ on the calling freq? 146.52 - CSQ? I was on top of a mountain this afternoon with my 5 watt HT and called out but sure could not hear anything back. I'll try again tomorrow if you could advise the best etiquette. Thanks.
146.52 is specifically prohibited from VHF contest operations. The rules are all on line and easy to look up.
Try 146.55, 146.58 and other popular simplex frequencies.
