• Feb 2nd 2021: Guest Version V7 now Live - V7 is free to use. It is similar to the full featured GUI but has the following limitations: no personalised listener Id, no Personal Logging, ChatBox is read-only, no tuning guides, no mobile version and V7 connection time limit is 4 hours. Also, at busy times, Registered Listeners have priority and some V1 & V7 users may then be disconnected automatically.

• Nov 14th 2020: Flex 6500 now SOLD

• Sept 2nd 2020: INCREASED COVERAGE ON 20m - The whole of 20m is now covered by an SDRplay RSP1A. This is connected to the WebSDR server via the 'rsp_tcp' interface written by Bas ON5HB.

I may need to optimise the parameters, please bear with me during this initial testing period.

Coverage is from approximately 13983 kHz to 14367 kHz. Default zoom level is still X1, you may prefer to zoom in further to examine signals more closely.

• Sincere thanks to the following listeners for the generous donations they made before registration was introduced. As a token of my appreciation, all of these listeners have complimentary GOLD access :
  FN, AnthonyC, MikeM, G0PZX, PhilC, GM7ESM, Mart Ysselmuiden, F5LPM, M6TAS, GW8TRO, G4DJK, G4SJG, MD, AllanC, G0SXY, ScottP, 190919, NigelC, Volvo1984, Steve - M5MOW, G4NGV, BarryH, G4BIM, G0PWC, G3TDJ, GD0SFI, PeterH, NevilleP, MW0XAP, G0LUB, JeremyC, PhilipS, 2D0DRM, EI2DJ/G4GXN, G3UEQ, PA1BSC
• Many thanks to Pieter PA3FWM (University of Twente) for creating the original WebSDR and for making it widely available so that other sysops could add to the network - Twente WebSDR

• Thanks to Petr OK2CQR at HamQTH.com for the use of his CSV feed which now provides the raw data which I use to generate the waterfall spots

• also to Bas (ON5HB) for developing and sharing rsp_tcp on GitHub - his generous efforts make it possible to interface SDRplay devices to the WebSDR server. This middleware enables me to use a RSP1A on 20m to cover the whole band
