I have an EMF 390,newly running on Rev 2.35 and I notice that there is no Zoom 2 in RF Spectrum mode,on the 153 to 534 Khz band,all the other bands are OK.

Also,its not really a bug,but I find it annoying and unergonomic,
that usually when I change band ,on the Rf Spectrum Analyzer,the band
opens at Zoom 1 and I have to remember to Zoom Out to see the whole band.Not sure if it is on purpose or not.But it bugs me.

Thirdly,where I am living at the moment,by the sea,has many signals in the 1G to 2G band.1100,1250,1600,1700 many channels of cordless telephone,1800 1900,2100,according to my Cornet ED88T Plus.
Many seem to be navigation beacons in the harbour and old mobiles.
I personally would be willing to pay more for an EMF 400 that included an antenna for the 1G to 2.4G band.

Further,at the moment the RF Browser sees the signal but not the frequency,then to change to Vertical gives the frequency,maybe,and then the RF Spectrum can be searched.Which is a long cumbersome process.
It would be great to have the frequency in RF Browser mode.
And would be helpful if the RF Spectrum automatically opened in the band with the highest current signal from Vertical and RF Browser modes.

Thanks for the fine devices and excellent customer service.

you guys rock !

Hi paul,

The 153-534 only has 1 zoom. That is intended.

The zoom 1 default is also intended because the Zoomed out screen is slow.

I will tell that to my supervisor and to see what he thinks.

The RF Browser doesn't include frequency because it needs to calculate and refresh fast. It can't scan the spectrum bands.

That's a good suggestion but it would make it confusing to some customers.

Thanks for the feedback!!

Thanks for the prompt reply.

Zoomed Out IS slow.But Zoom 1 center is arbitrary,and rarely covers
the highest signal,so one must Zoom Out anyway to see what is there.

My suggestion may not be too confusing if there were a User Option for
original or new "Auto Band" mode.

Just musing.

thanks for you attention to detail

We will discuss the Zoomed out, we might implement it on the next firmware revision.

But the Auto band is hard, because other screens do not scan the spectrum and it takes time to scan all the channels.
