Andrew,

Can the FT-530 and/or FT-470 work cross-band in
non-duplex mode?  I had an IC-W2A (predecessor to the
IC-W32A) and it worked great for full duplex sat
operation, but only in full duplex.  That is, there
was no way to turn the 70cm off while transmitting on
2m, so it could only be used with headphones.  Granted
that this is the best way to operate the sats, but
sometimes headphones are unavailable or impractical,
so I'd like to at least have the option of working the
sats in non-duplex with the speaker.

One thing to look out for if, like me, you are
interested in a 5 watt HT.  Many HTs that are
advertised as "5 watt" will only produce 5 watts if
connected to an external 13v p/s or a special battery,
with the supplied battery giving much less output.

73, Bill NZ5N
