Yes i know is the Rx/Tx Switch on the Output side. G4SDG searching for the Info on start of this treat.
Max 0,6 dB loss according to Data sheet. That is not the reason for the poor Performance.

Works also fine by me, but a little more Power where nice for my portable Equipment - 45cm Offset Dish.
Checked again the Internet and found this one:
FMS2031-001 10W GaAs WIDEBAND SPDT SWITCH

Hi Ismo,
yes I removed the mid Cover completely and remove the xtal with two soldering iron.

Hello Ismo,
yes it's 2,2 µH Choke or Inductance.

Then you can not use them unmod, wobbled +/- 5 to 10 Hz, I have testet now with a second one unmodifiet.

Naturally with unmodifiet LNB you have a lttle bit of wobble and also drift,
but you can listen to a SSB QSO easyly.
Sometimes use the VFO Knob to compensate the drift. Perhaps you can stable the LNB by put a PTC direkt on the xtal.
I dont know the 67269, so i dont know how is wobbled.
Best Way is to mod a LNB and use a tcxo or a gpsdo indoor.
Hello all,
GOOBAY 67270 works fine when you put him in a shadow, like in a Box that no Wind cool them down or Sun heat him up.
Also easy to modificate, only desolder the xtal an put 2,2 µH and 18 pF to the PLL.
I am using the Triplexer from the Forum here and the Leo Bodnar GPSDO.
use the following Frequencies for the PLL give Output on >>>
26.525640 MHz >>> 144,550 MHz
25.787172 MHZ >>> 432.550 MHZ
23.699998 MHz >>> 1246.550 MHz
There is no Diverence in the Output S/N, messured with ICOM IC-R8600@2,7kHz BW.
