Hello, after 10+ years on the shelf I got my RF-550 receiver onto my desk. I thought I had a manual too but can't find it. I need a manual to get anywhere. Any pdf available? I am not sure if the RF-550 qualifies as a premium rx. Please accept my apologies if I am wrong. vy 73 Heinz DH2FA, KM5VT Von meinem iPhone gesendet
