I didn't know that I could update the firmware (3.45) for my RF Explorer WSUB1 PLUS handheld spectrum analyzer, but when I finally checked the RF Explorer website, I pleasantly discovered that I could and that a Ham (Radio) Field Meter mode had been added! Starting with firmware v3.25, all RF Explorer PLUS models can perform specific W/m2 or V/m field strength measurements for all sub-GHz popular Ham frequency bands. This feature is developed with contributions from Martin Lynch & Sons (www.hamradio.co.uk)You can use this feature to convert the RF Explorer Spectrum Analyzer into an effective, accurate and easy-to-use (TBD) field strength meter to easily check power levels being transmitted by your antenna at a reference distance, and check if transmission levels comply with local regulations (called Electromagnetic Compatibility Advisory Bulletins in Canada).
I'm testing new antennas (vertical, dipoles, loops loaded antennas, etc.), but I realized that it would be very useful for use on the 22m ISM band. RF Explorer recently added the 11m band, so I sent off an email to see if the 22m ISM band could also be added.
I haven't used the RF Explorer for a few years (bought too many toys and step learning curves or reading manuals aren't my forte ;) ). But the Ham mode piqued my interest, except you have to buy a license to use it, which I'm asking about since the link provided is for another license type. So I also asked for help on this, as I don't mind buying a license to experiment with it because I'd like to know how well the estimation equations we used compare to real-like metered readings.
If anyone has an RF Explorer and has used the Ham mode, I'd like to hear about it and if it was worthwhile to buy the license (on sale for $99 US).
