[Premium-Rx] R&S EK071 LSB upgrade

[Hans.Hamradio]

Hi Premium RX friends.

Many thanks for those who give me support in the Rohde & Schwarz EK 071 LSB 
upgrade + filterchange.
1.400 Mhz/2.35 Khz filters (50 Ohm impedance types!!) has been obtained and 
fitted. USB is now much more pleasant and some mods still to be made on the 
LSB part.
I understand that Jacinto Lirola did some mods on the audio part because 
normally only USB is on the speaker.
I like to get in touch with him and are looking for his mailadress. Could 
anybody help me with his emailadress??

Please get in touch with me if you made simular mods.

Best regards from Amsterdam NL and enjoy the hobby.

Just obtained a very nice R&S EK071 without any damage and in excellent
working condition. However!! the usual battle of fitting a the LSB filter +
relais should be started soon.
The present installed USB filter is EP089.3085 (-3.4_-0.3 kHz)
So I need the LSB filter EP089.3079 (+0.3_+3.4 kHz)
Allways found the SSB filters of R&S too wide but i found in the service
manual that beter filters are available like the  type EP089.3256
(+0.5_+2.6kHz) and EP089.3285 (-2.6_-0.5kHz) Filters are made by STC which
has been also a standard supplier to Racal and others.
Please let me know if you have a filter as requested,know a source or are
has been carried out a simular action before.
