Jeff, My e-mail has been down for a couple of days, but in case you didn't get a reply, the birdie is on 436.8, i.e. AO-27 and SO-50. Still there, and according to a Kenwood tech rep, it isn't that easy to fix, and won't be. I use another rig, but some have reported that a mast mounted preamp allows them to work it. Alan WA4SCA
