[Yaesu] ft-8900 need help with cross band function....

[KB0NLY]

Yep, its a dual band but single receiver.  Darn nice radio though, if you 
don't need a true dual receive dual bander get one, they are a great radio 
for the money.

I should have included in my original reply why i traded in the 8900 for the 
7800's.  The only reason was i needed a new radio for the wife's car and i 
wasn't using the 8900 to its full extent, i used it maybe once on 6m and 
never had a use for 10m around here, being that the 8900 is an expensive 
radio i was able to trade it off for two new 7800's with only a little cash 
to boot.

Whats really nice is i have to vehicles with the same radio now, i 
programmed them both the same using FTB7800 and now i can hop in either 
vehicle and be right at home.  Also, the 8900 to 7800 swap was super easy, i 
just left the remote head and speaker cable in place and swapped the control 
head and radio body for the 7800 as the cable is the same for both models, 
though i did need the new control head bracket which the 7800 came with as a 
free remote kit at the time i bought them.

73,

Scott
