…My new radio transmitters arrived. I had a chance to test them today a little. As long as my flash batteries collaborated with me, they seemed to work like a charm. Have to try them again soon with better preparations (and with back-up batteries!), because I didn’t have the change to try the transmitters in the capacity of a cameras remote control yet. Nor did I test how far does the signals carry… So maybe next time I take them outside for a test.
