This week we welcome Dave Hunt as the 8000th member to join the unofficial SDRplay Facebook user group. This amazing group was founded by Paul Jones 3 years ago and these days he is assisted by admins Preben, Kyle, Brian, Jay and Angus. The beauty of a Facebook Group is that it is a trusted/friendly space where once you become a member you are trusted and it ticks along nicely without the spamming and trolling which can occur in un-moderated forums. The SDRplay FB Group can be found here: https://www.facebook.com/groups/sdrplay/

There is a recent release of Win4K3Suite which now offers support for the SDRPlay RSP1A for use as a panadapter on the K3, KX3 and KX2. This release also offers a few enhancements in display performance as well as ClubLog spot aging.
Win4K3Suite is the ultimate control program for your K3S, KX3 and KX2 supporting all options as well as the KPA500, KPA1500 and KAT500 on all radios. It supports the P3, and allows the use of the SDRPlay family of RSPs as a panadapter.
Win4K3Suite includes virtual port technology allowing sharing of up to 6 software programs or hardware devices with no conflicts.
You can see some videos on Win4K3Suite here:
and some reviews here: http://www.eham.net/reviews/detail/11214
There is also Win4Yaesu Suite for the FT-991 / A. Based on Win4K3Suite, Win4Yaesu offers complete control of your 991 and 991A transceiver and includes support for the SDRPlay RSP panadapters. It provides access to menu items, frequency memories and has built in virtual port technology allowing sharing of the radio with third party software and hardware. The sharing mechanism is extremely robust and you can operate in contest mode for days.
Win4Yaesu also supports HRD LogBook and DM780 replacing the control program with a much more capable and robust front end.
You can see it in operation here:
Win4Yaesu also supports the SDRPlay RSP software defined radios as panadapters with a TR switch as shown here:
For contesters, Win4Yaesu supports N1MM+ completely including interoperability with the N1MM+ spectrum.
You can download a free 30 day trial here:
Be sure to read the first 10 pages of the manual for trouble free setup. (Hint: disable RTS in your radio)
Many thanks to Win4K3Suite author, Tom for his ongoing enthusiastic support for the SDRplay family and our ever growing community of RSP users.
DavidCasler , KE0OG has just created this very watchable introduction to the RSP and SDRuno – I recommend sharing this link to any friends who as yet haven’t taken the plunge with SDR – especially those folks who have happy memories of exploring the airwaves using much more ancient technologies! This video is especially good at illustrating the visual impact of an SDR receiver.

Many thanks to the RSGB who have given us permission to share Mike Richards’ review of the RSP1A which was published in last month’s RadCom – Click here to read the article
The latest update of SDRuno (Version 1.22) released this weekend has updates and features which should please users old and new.
For the newcomer to SDR radio, whose only experience may be from using a traditional hardware communications receiver, we’ve made it much more obvious how to turn the radio on and off with a very clear, colour coded Play/Stop button which toggles. We also realised it wasn’t clear to everyone where the AF Gain/Volume control was – this is now much clearer. Building on the popularity of providing pre-set frequency ranges of certain ham bands which we introduced in V1.2., this time we’ve gone a step further by adding pre-sets for all the ham bands and also the most popular LF/MF/HF broadcast bands as well.
Above: Play/Stop, Volume control and Frequency Band selection which brings up a choice of 3 sets of bands as shown below
The documentation has all been updated to reflect the latest version. This includes both the SDRuno user manual which can be downloaded from our Documentation page, under ‘Software’ and ‘SDRuno User Manual’ as follows:
and also the highly popular SDRuno Cookbook hosted by Paul NN4F which has a link to it from our Documentation page, under ‘Community Guides’ and ‘SDRuno Cookbook’ as follows:
For the existing users, here is the full list of enhancements made, followed by an update to our roadmap for future upgrades.
• Support for 1366×768 default layout
• ADC overload detection in AGC off mode
• ADC overload acknowledgment system to avoid lockout condition
• Custom step size for each mode
• Band Button Groups (Ham Lower, Ham Upper, Broadcast)
• Two additional SP1 width presets (2560 and 3840)
• Additional menu option in memory panel to reset column widths (helps when upgrading)
• Scheduled Recording
• Auto update
• Registry reset now only clears 1.2+ entries
• SP1 Window max size supports 4K displays (3840×2160)
• Small improvements to the memory panel (panel width and field width changes)
• Improvements to the IF output mode
• UTC time fixed to 24 hour format
• Play!/Stop button colour coordinated
• Move MUTE button to make way for VOLUME label
• Moved Squelch value display to the right
• Log10 SING error
• Aero support detection to try to prevent rendering issues
• Freezing when switching to HiZ port in gain mode
• Gain “pumping” issue when in gain mode
• Settings panels not displaying properly when “un-minimised”
• Zoomed in frequency scale drag out of bounds bug
• Noise floor measurement bug
• Improved RSP error handling
• Sample rate change causing spectrum display issues
• Device selection bug
• SP2 CWAFC drift issue (Zoom/window size/freq display) – will be addressed in 1.23, workaround for now is to zoom out fully in the SP2 window and then the CWAFC feature will work.
• IF output mode disabled SP1 spectrum mouse clicks – temporary issue until LO is separated from the VFO (see plans below)
Following on from the 1.21 release where we outlined the features for coming releases, we have updated our plans, as shown below. The purpose of publishing this information is to give people an insight to the development plans but it is NOT a guarantee of the exact feature line-up and we cannot give release dates.
1.23 Intermediate update
• Recording of selected signal only (either I/Q or audio) to WAV file format
• Selected signal piped to VAC in I/Q format
1.3 Major update
• Separation of VFO and LO frequency control
• Frequency scanning
1.31 Intermediate update
• Remote client for network based streaming I/Q server applications
1.4 Major update
• Addition of new API for third party plugins

Many thanks to all those of you in the community who have helped shape our ongoing improvements to SDRuno with comments and suggestions – keep them coming!
We have had quite a few people blowing up their RSPs over the past few months. Most people understand that there is a practical limit as to how much RF energy can be allowed to enter from the antenna socket to the delicate circuitry within. We try to make sure everyone understands that this must not exceed 0dBM ( 1mW) of RF power – a higher level of 10dBM (10mw) is acceptable for short periods. Most people know not to connect the RSP to a transmitting antenna.
However, what is sometimes less well understood is this:
- Disconnecting the USB while leaving an antenna connected which is presenting signals stronger than 10dBM to the RSP antenna input, does not help matters – if anything it makes it worse since the RSP is designed to have the USB connected to ensure the antenna switches are powered up in a known state.
- Tuning the RSP to a different part of the RF spectrum than the frequency of a potentially damaging transmission makes no difference whatsoever since the damage is caused by heating effects which will exist at any frequency (it’s not like adding a traditional attenuation as would be the case if you were mechanically switching in say, a chunky resonant LC circuit tuned away from the transmitter frequency).
Please take care to use proven protection techniques such as using protected RF or IF outputs from transceivers when using the RSP as a Panadapter, using a protection device or ensuring if connected to a dedicated receiver antenna that it is positioned such that the total energy received by the RSP remains below the oDBm level.
There are lots of discussions on our forum on the topic – just go to www.sdrplay.com/community/index.php and search with words like “protection” to find comments on the subject and links to recommended techniques.
Or join the Facebook group: https://www.facebook.com/groups/sdrplay and describe what you are trying to do, to get real advice from other users who have found successful ways of ensuring they don’t fry their RSPs.
