[Premium-Rx] Racal RA3791 firmware oddity

[John Nelson]

> OK, I've had a play with three of these now.. And it was not until I
pulled the last one out this morning that I found your behaviour. The reason
- firmware version P90550/04, well at least before P90550/08<

Interesting. My receiver has firmware version P90550/08 installed. The DSP
firmware is P90553/07. I'm wondering why it's not behaving like your later
versions.  

> On receivers with P90550/08 and P90550/09 I don't get that behaviour. It
doesn't display an address unless in master mode. For firmware version
P90550/04, the address displayed is dependent on dip switch settings, so you
can set SW3 to 1 or 99  as you discussed and that's what you'll see. If you
like I can pop a copy of P90550/09 on my webpage if you want to 
try later firmware?<

Many thanks -- I've downloaded a copy of that and will see whether it's any
different. I'll also speak to a colleague who has the /09 firmware installed
in his receiver after the holiday and see whether his is different.
