I am awaiting delivery of a Flex 6600M, my first SDR. I intend to use it locally with the front panel and with SmartLink using my iPad Pro 10.5. Spectrum is now offering to increase my download speed from 100 mb/sec (actually 60 as measured by Ookla) to 400 mb/sec for $25/month. Would this upgrade improve my station's performance at all? Thanks.
