Okay ,I have to be having a serious brain f*rt here but I'm having issues getting my spectras to operate in duplex or repeater use.I am familiar with the RSS,programming,tones and etc.I'm even having the same issue with one of my vhf Astro Spectras that use CPS.And with the same results on all radios I'm convinced its operator error here lol.Problem I'm having is radios will not key up repeater until ptt is released and opens repeater for a second.Tried on multiple repeaters that require tones and csq with same result.If I put radio in "direct" or "talkalround" mode radio transmits beautifully,I guess I should also note that I have no problem listening to the repeater (when others are talking).
