Have you found a good source for band filters?  A kit or design software would work. I have seen a number of tunable ones on eBay.  I have a SA with a tracking generator that I can test them with - it goes up to 1.5GHz.

you can get away without usb relay if you use the ptt inside the pluto(plus)

regardless if you use the plutoplus (and its ptt signal) ... or if you use a pluto (rev b or rev c/d) .... with the fw from evariste and ptt circuit added

both ways you do not need that usb relay to have a ptt signal

lna for rx should have a filter for the band of use (thats why i was BEGGING for a band data out with usb relays ... at  best one for rx and one for tx)

tx should have a power amp (with needed predriver etc)

Thanks to Simon for such a great program to use with this!

you can get filters ready to use on aliexpress and you may also find saw filters at mouser or digikey

... let me do a guess ... a nanovna :-)

it has a clock of max 300 megs and up ot 900 or 1500 is done with 3dr or fifth harminic (so perfomanxe is only "soso" at higher bands)

go and get a nanvna v2 ... or saa2n ... or v2plus4 .... or ...litevna or ... .. ...  (so many newer designs now on the market)

with clocks up to over 4 gig (newest designs 6 gig)

dg9bfc sigi

ps i tune the poty feed with v2plus4 ... cross-checking with saa2n and kc901

Hi Simon

This is the first opportunity I have had to post as have been away for work.

But I have the exact same problem here.

My system is

Windows 11 PC

Pluto connected via network

Berhinger USB UMC-22 audio interface.

The issue was still there with my USB head set combo

Last Sunday when I went to TX the audio was all garbled to the point that it was unusable

I have checked more or less all that has been suggested here including a DFU refresh and a reload of the Pluto firmware but with no change.

Looking back at the PC update history all of the issues seem to have started after the most Win 11 update.

I need to find and look at what this update did.

Now I am back home I am going to roll back the update and see if this fixes my issues but will keep following this with interest.

HI Simon, any idea on the release for this fix ?

Thanks,

Ben
