"Do you have an Aurora with 819 RF out to test the receiver in VHF E standard" ?
Hi Jerome,
I still have the original multi-standard Aurora converter, this device doesn't have a modulator and for 819 lines I use the System E modulator that Wilfrid made for me. Outputs to channel F8
Also for 819 lines the Philips GM2891 pattern generator donated to me by Mr. Poulain. It's the /13 version. Similar instruments were made for USA standard M (/60)and CCIR 625 lines (/50). Never seen a 405 line version.
Instrument uses an early UHF valve, the EC80:
