Hi Yuri & Luca the passive bpf filter shows approximately 3.9 dB of insertion losses @ 144 MHz and 3.6 dB at 146 MHz with approximately 1,3 dB ripple and a usable 138/148 bandwidth (It could be better tuned, but is it really necessary to spend more time on it ? ) SAW filters are not exactly efficien...

Hi Yuri

I have a desperately empty and useless connector on my SDR back panel :-d
if you need a beta tester for your AFT05MP075N version of the transverter, count me in. Even a simple set of gerber files will be ok

Wish you all the best

Tnks Yuri In other words, quite a lot of good news. I'll ask Aivars if he can send me a pcb of the new release (if available) I have a small amount of AFT05MP075N in my junkbox (who could ask for more ! ) But I'm affraid you'll have to make a new release in the next future, as NXP has announced the ...

Hi Yuri

Could you please give us some news concerning the 2m transverter ?

I saw Luca's build and I must admit I'm very interested if this version is stable

Oh, by the way Yuri PCB release 3.5d and schematic release 3.6D, IC13 is NOT grounded. ... thus causing probable glitches in the Alexiares SPI protocol. Pin 19 and 1 ( OE1/OE2) could go high and stuck all communication with Alexiares address decoder A short strap with the closes gnd plane is advisab...

Hi all My name is Marc, slowly building an Anvelina board. ... and for this reason, I have some probably stupid questions. First of all, two notes in the schematic are a big mistery for me (as written in cyrilic alphabet) https://imgur.com/a/e6ugDud https://imgur.com/a/e6ugDud could someone translat...
