[ICOM] Icom 7200 at Dayton Big Disappointment???

[Anders Janis SM4RNA]

Yes, but on 10m -+2,5kHz should be used, and is on i.e. the DR-03T ( 
http://www.alinco.com/Products/DR-03_06/ ) and the FT-8900. Older radios 
like the IC-735 or IC-725 is to wide both in RX and TX.

5 khZ (+/-) deviation requires a 16 kHz bandwidth,
if I remember correctly, due to the sidebands that
are generated out beyond the expected 10 kHz
bandwidth.
