Henning,
The model does not have the fact that the transformer is FT43 material with more than
desirable number of turns so by 100mhz its into the absorptive range.
The actual sweeps show its has gain at 120mhz but well down not due to the device but?
the rather horrid layout, transformer, and strays.? Never mind the lossy g10 under it.
Try the same model with 3904, if it not well down the gain curve at 30mhz you model is broken.
