there is also this one:

which doesn't look that bad except that it's good only for Es'hail-2 traffic: it doesn't work under 2400MHz due to the SAW filters used...

But in addition you need a LO!! It is not included..
-
You should ask Darko if he had tested the BU-500 up converter on 10m Input. The LO is able to cover 10m.. I am running this with 2m input and this works.. also 70cm input
Is there any European dealer where that device can be purchased from?
What are then the costs?
Looking on the manufaturer's site I read some USD169 (USD99) plus USD50 shipping. Think some customs tax has to be paid when shipped from Taiwan into EU as well.

Darko do the shipments from Austria for Europe...

I have seen, there are 2400 MHz SAW-Filters on market. 3dB-BW was 18 MHz and Z-In/Z-Out= 50 Ohms. Could be ideal fur surpressing unwanted mixing products, but does anybody know about maximum allowed input level for filters loke this?

Look at those filters: https://www.mouser.de/new/triq…5033-signal-conditioning/
High att out of 2,4GHz and power handling to 31dBm.vy73 DB8TF

if you tweak the oscillator you could also go for this https://shop.kuhne-electronic.…3+G2++Transverter/?card=4 . Will take some time to craft but might provide aditional skills and fun.

Hello people. I'm new here,try to pick few ideas fot full transverter - rx/tx, who not depend by tranciever frequency. The last one will choosed by amateur. In any case i have 3 ways to get full transverter for satt transmiting and receiving.
-
My solution to this issue is to insert a Russian transverter (cheap but stable), between the LNB at 432 and my ts 2000 at 28 MHz. I assure the success of this solution, the only issue to cure is the gain reducing with the the transceiver or adding ad attenuator on the lnb line id the noise is too hign.

Hi Alessio,
ZF of 432 MHz from the LNB with the LO of 25,xxx is the first part of the worse S/N on RX.
The IF filter of the LNB was designed for a passband around 739 MHz.
I think the better way is to convert the 739 MHz to 50 MHz.
Most KW transceivers have this frequency range.
Using the IF on 28 MHz for the uplink is problematic because of the image rejection. Maybe the construction of the converter after Remco's suggestion with two mixers helps.
But here, too, a narrowband bandpass filter is needed.

A fellow HAM also uses this solution. The 28/432 MHz Transverter fom "Transverter-Store" in between ....
