HAM RADIO DELUXE WATERFALL NOT FULL WIDTH SOFTWARE

This is a very short list of radios made in the last 5 years or so - iCOM IC-705, IC-7300, IC-7850/51, IC-7610, IC-9700, Kenwood TS-890S, and any Flex Radio.

Software can only produce a panadapter display if the transceiver can produce data via its CAT commands or via IQ data. Some of these transceivers have the ability to display it on an external screen. Some transceivers have a display that looks like a panadapter display. So it’s not possible to create a panadapter display from the audio output of a typical ham transceiver. To net this out – if you connect a soundcard with 20 kHz bandwidth to the audio output of a typical ham transceiver that has 2.4 kHz of bandwidth, your “waterfall” is limited to 2.4 kHz. Using the new Yaesu FTdx101D/MP as an example, the audio frequency bandwidth is 2.4 kHz on SSB.

The limiting factor is the AF bandwidth of ham radio receivers. By comparison, commercial FM radio stations are given 16 kHz of bandwidth. But the bandwidth of the soundcard isn’t the limiting factor. That falls well short of the full bandwidth of a ham band. That’s almost enough room for 6 SSB signals. This is roughly the bandwidth that the human ear can hear. Soundcards have a bandwidth of about 20 kHz. When soundcard-based digital modes became popular, most of these programs displayed signals in a “waterfall.” These waterfalls – still used today – are limited by two factors. We all know that none of these had any method for computer control. It wouldn’t surprise any of us that our old Heathkit, Drake, Collins, and Hallicrafters gear couldn’t produce a panadapter display. What is conceptually hard for most folks to understand is this – no software can create a panadapter display from a radio that isn’t capable of producing one. Without getting into the semantics of the differences, the point here is… everybody wants a broadband view of the RF spectrum. These words are often used interchangeably.
