The recording is a function of the software you use with your dongle. Make sure to point the recording to a drive with lots of space. You can easily chew through 200-300 MB to record 96 kHz of bandwidth for a few minutes. But you get everything in that bandwidth, so you can play around with it later. HDSDR gives you the option to chop the recordings once they reach a certain size, so you don't exceed any limits on your hard drive's file system. To make use of those SDR recordings with other software, you may need some virtual audio cable software so you can have the audio output from your SDR software go into another program. Some Windows 7 systems have a "Stereo Mix" recording device that can do the same thing, without having to install additional software. Receive bandwidths vary with these devices, of course - from 192 kHz from the FUNcube Dongle Pro+, to around 3 MHz for the RTL dongles, 8 MHz with SDRplay, and up to 20 MHz with the HackRF devices. These SDR devices are not that expensive. Of course, the "not that expensive" assessment is relative. I can buy 7 or 8 RTL-type dongles, or the SDRplay, for the price of a certain 2m/70cm FM HT discussed ad nauseam in this forum. The HackRF Blue was just over $200 through a crowdfunding drive, and the HackRF One retails around $300 from a few different sellers. Since I'm not purchasing a new IC-9100 or a used radio like an IC-910H or IC-821 for a home satellite station at this time, it's not hard to look for other items to try out for satellite work - or just for general receiving. They all have their places - the RTL dongles are OK for VHF/UHF receiving, as they don't typically receive below 24-25 MHz without modifications. I have one of those dongles at my office mainly as an FM radio, but sometimes I will punch up ham repeaters, weather radio, or other stuff. The FUNcube Dongle Pro+ could be used as a receive-only station copying telemetry from AO-73, if it's not with me in the field or back yard. I'll probably keep it with me when I travel, since it is so small. The SDRplay might end up being my first choice for an SDR receiver when working satellites. And the HackRF devices, as transceivers, could do a lot more than just receive. Being able to see the entire 88-108 MHz broadcast FM band on my screen using a HackRF device (either one) is impressive! (Only my Win7 laptop, of the computers I have at home, is capable of seeing the full 20 MHz broadcast FM band - my tablets can't handle that much bandwidth) 73!
