    Go to the DEMI website http://www.downeastmicrowave.com/ and then go to the product manuals section. There is a PDF manual there for the L144-28. They are very (re)configurable in the field. The manual is quite detailed.

    With an IF radio like the 1500 I'd opt for a split IF and also reconfigure the drive level to be more than the -20dBm. The -20dBm TX drive level is typically what is needed for the JA brands. For the transverter port equipped Flex gear you will want to go with what the DEMI manual describes as "mid level" TX IF drive configuration. Once the drive level is reconfigured it will be pretty much plug and play with the 1500.
