Re: * * * VALUE L1-L2 TX136 * * *

Hubert,

The value 680nH is correct. L1, L2 and C11 forms a 12MHz LPF filter to attenuate harmonics coming from the mixer IC2.
Check first that the 10MHz square wave (CLK/2) is coming to IC2 pin 14.

Re: Time goes by

Hello Hubert,

Nice to hear that you like JUMA TX500. Unfortunately the "small" kits are discontinued. We are currently focusing on JUMA PA1000.
My plan is to share also the remaining PCB Gerber files of the "small" Juma kits soon, including TX136.
