T-MIX
1) Alignment requires an sweeper
2) Coarse “145MHz” *)
3) Connect sweeper to the external VFO input: J2 pins 8 (Gnd) and 9
4) Set sweep to 10,000 to 13,000MHz, app. 0dBm (700mVpp) *)
5) Mode “FM”
6) 50

Demodulator (10W) and viewer (scope) at Antenna output
7) Sweeper output to zero
8) “TX”
9) Set sweeper output to app. 1W at antenna output
10) Tune L1 to maximum
11) Tune L3 to L9 to maximum and flat response in the range of 10,385 to 12,385MHz *)
12) Reduce sweeper output when 1W at antenna output is exceeded
13) Tune C32, C35, C43 and C44 to maximum and flat response in the range of 10,385 to
12,385MHz
14) Go back to 10 until result is satisfying: Flat response (+/- 3dB in the range of 10,385
to 12,385MHz
*) With “Coarse” 145MHz and sweeper from 10,385 to 13,385MHz the output is 144 to
146MHz
