I know this is probably a bit off topic here but just thought I would update you on using my FT-450 on digital modes.
As Bonnie pointed out, from this graph ... http://www.projectsandparts.com/misc/ft-450tx.gif ... you can see that the published FT-450 Transmitter Specifications: "Audio Response (SSB): Not more than -6dB from 400 to 2600Hz" is nowhere near my measured results. This was using a Sound Blaster Audigy 2ZS and Signalink SL-1+ interface (which have been in regular use with other rigs for 3+ years without problem) After contacting Yaesu a 3rd time and asking their engineer to look at this graph again their final response is this: "Sholto: At this point if you believe your radio is not up to specs to analyze it properly. I repeat that the information you sent does not indicate a problem. 73 (name witheld) Amateur Radio Technical Support" Regardless of whether there really is a problem with this rig or not if a Yaesu engineer cannot ascertain that a roll off of more than -26dB within the stated passband is greater than the published -6dB specifications then there is no realistic hope of asking them to fix it. I doubt I will ever buy Yaesu again. 73 Sholto KE7HPV
