Flex 5000a Output Power Control

Hi I am hoping you can help a fellow "flexer", I am finding difficulty in achie= ving a smooth power increase whilst using SSB. A little more information needed I know, but what I mean is the following: I owned an FT2000 and when I was transmitting,my power meter would stay stea= dy at the required power output when my meter was set at peak hold. This was= with the linear switched in or not. My challenge (more noticeable with the linear in, usually run 200 watts) wit= h the flex is that my meter will show an average power output of say 110 wat= ts then on the next voice peak may shoot up to 200 watts. It would appear t= here is no control or smoothing out of my audio input and I am not to sure w= here to start. I spoke to a station today and he said that although my signal was clear and= strong but there appeared to be some Intermodulation being introduced on peaks (probably because of the s urge in power with no control ?) I assume hang and attack times can be adjusted to help ? But I am not sure. I use a Tokyo Hi Power HL700b with the flex wire connected to the ALC socket= on the amp I use a Flex 5000a Hopefully you can help. 73 Glenn M1 AQO
