• I just bought an SDRplay RSP2 receiver. It seemed to have good specs for the price. I already had a FunCUBE Pro Plus which covers roughly the same spectrum but it can only support a 96 kHz wide panadapter, which is a bother on VHF. The SDRplay RSP2 can be set for 500kHz, 1, 2, 3 ,4, 6, 7, 8, or 10 MHz (10MHz is at a lower bit rate at least on SDRconsole). This is neat because you can watch the whole of the 2m ham band or the 70cm band. (Not both at once).

    The native software for the RSP2 is SDRuno which apparently was built from Studio1. It is OK, but a bit odd. For example each receiver has buttons for the HF bands and 2m, but not 6m. The buttons on the subsequent receivers don't work at all if RX0 is set to a VHF or UHF frequency. Each receiver can have its own panadapter and audio panadapter so you end up with lots of windows and it can be rather confusing working out which receiver relates to which panadapter. Having a separate panadapter for each receiver is pretty pointless since each receiver must be inside the maximum 10Mhz of bandwidth. Although you can have panadapters zoomed in to show smaller sections of the 10MHz spectrum available. Personally I would rather have all of the receivers displayed on a single panadapter. The HF band buttons only really work on RX0 and even then they are extremely annoying. I would have expected that pressing the button would switch the receiver so that the panadapter showed the band of interest... but it doesn't. If for example you have the sample rate set for a 6 MHz bandwidth and you press the 20m button, the receiver sets the current cursor position to 14.0 MHz. If the cursor happens to be at the center of the panadapter you get 11.5 MHz to 16.5 MHz on the panadapter. The memories work exactly the same way. If for example you have 5 repeaters setup as memories, each time you click on one the panadapter shifts and you lose visibility of the other repeaters. This really bugs me. The SDRconsole memory management is 1000 times better. Yeah I know you can lock the Local Oscillator, but it is still clunky.

    Everything you look at on UHF or VHF is in a band. Aircraft band, Marine band, 70cm ham band etc. When you click on a band memory (s1b file). It should set the panadapter to show the band of interest or at least as much of it as possible. If the band is wider than 10 MHz, you could always save separate high and low band s1b files. Then when you click on a saved memory the panadapter should stay fixed and the cursor (receiver) should jump to the channel that you want to listen to. the developer needs to exploit the advantage of having a wideband panadapter, instead of thinking of the radio as a single channel receiver. The software is actually pretty good and it works OK. The panadapter works better than the one on SDRconsole which is strange and unpredictable especially if you change bandwidth to a different sample rate. Just a teething problem I guess. SDRconsole is pre-beta so it is unfair to be critical.

    SDRuno is really very good, but some things do bug me. My main gripes about SDRuno are.

    1 the band buttons should make the panadapter display a band, not just jump to the bottom of the band.
    2 the band store should remember the current panadapter settings and actually be a 'band store' not just a directory
    3 Saving a workplace is great except the receiver frequencies are lost not recalled. On a program restart or change of workplace, all of the receivers pop up on the same frequency. So you have to go and set them all to the right channels again.
    4 you cant set the bandwidth of a receiver without opening its audio spectrum display window.
