SDRuno 1.41 open beta 2 has been released

SDRuno 1.41 open beta 2 has been released https://www.sdrplay.com/sdruno-beta

As before please read all the information on the page. This is likely to be the last open beta before full release, so please report any bugs found via email and NOT through the ticket system.

As previously stated, the feature list for 1.41 is frozen so please do not report feature requests.
We would like to thank everyone that has reported bugs on the open beta 1 – we aren’t able to reply to those emails unless we have questions, but every email is read by the development team.

Mike Harwood’s latest SDRplay video comparing 4 mag loop antennas

Mike Harwood has made a new video comparing 4 different active mag loop antenna at various frequencies from LF up to 52MHz using two SDRplay RSPduos which allowed simultaneous spectrum snapshots of the 4 loops in action with real signals. These are loops from Bonito, Cross Country Wireless, LZ1AQ and Wellbrook.

.All four loop antennas performed well. None of the loops had a significant failing.  Some of the summary points are listed below:

Possibly the Wellbrook ALA1530N and the LZ1AQ were slightly better performers, but this is a marginal viewpoint.

However  cost and ease of set-up are key deciding factors

The Wellbrook and Bonito loops come fully assembled and ready to use.

The Cross Country Wireless LAA++ loop comes with an assembled mast amplifier and a wire loop, so a rigid loop assembly would need to be constructed by the user. The bias-T does not come in a case, so this would need constructing and the user needs to provide a power supply. None of these are difficult tasks.

The LZ1AQ has many modes and a separate box with switches need to be assembled to make full use of these. As with the CCW, the bias-T does not come in a case, and a power supply needs providing. This is the more difficult loop of the four to get working.

Cost – the Cross Country Wireless LAA++ and the LZ1AQ are by far the lower-cost options.

This is the second of Mike’s antenna comparison videos.

Here’s a link to the introduction to the series: https://youtu.be/yuG47e8hHTQ All 4 antennas shown here are highly recommended for use with the SDRplay RSP family of SDR receivers. Mike Harwood is  prioritising this activity around popular loop designers/companies who recommend our SDRs – that way both suppliers are on the same page when it comes to providing follow-up support to anyone following our recommendations for an SDR receiver plus antenna combination. Mike encourages you to add your comments to the YouTube video –  they will help shape future videos.  The MLA 30+ will be featured in the next video.
