Hi Mario, IK1ZQJ
I can suggest you to buy an SSB Electronics transverter model LT 24S output 1269 - 1271 MHz with an IF input 144-146 MHz, 10 watt output and a spare socket for a second XTAL to extend the band up or down the above centered BW
I have used the LT 24S to drive a pair of 7289 in a cavity amplifier when AO40 was alive and well
But be carefull.......because upconverters and transverters have their limitation in terms of frequency agility and probably it is more convenient for you to buy a second hand tranceiver with a 1200 MHz module installed as I did with a TS-790E at 850,00 Euro's and perfectly working.

Hello Folks, To work in uplink on the L band without a dedicated radio able to transmit
at 1269MHz an upconverter is needed, probably with if input is in 70cm.
Someone can suggest me how to use or build? I'm analyzing this way to save money instead of the station upgrade with a
new radio.
Thank you in advance.
