Well , its possible to  use the  emergency  vfo  , but that  results  in a very  unstable  signal , I   remember  down the  Tottenham court road , there  where  tea chests of  crystals , but that  was  1970 .. seems  a  lot  of the  traditional  firms have  closed ,
 
One  of the  £5  dds  with  a driver  would  work , but  they  want to  keep  it  standard
 
DS -   That's really  the  'correct'  situation  ,  that  -33 db decode, -3 db  lower than  normal  was  a  good  indication   that  the  system  is  working ,   over ranging  the  a/d  is the  only  problem . I think  dynamic  range is  60 d b after  processing  , is it   3 db per  bit  ?  8 bits  , 24  db + 3   that's   27 dB ?  500:1 ?   , but   by  removing    qty  2  mixers   and  2  oscillators   , [ may  be 3  oscillators  1 , hf-up-conv  2 , pll  conv osc  3  ref osc )  that  is a  lot  of  noise + jitter  removed  from the  signal  path as well  as   imd  from  2  mixers , I found  a attenuator  helped  for  mw  and  I have  a  mw-filter  , which  cleaned  up  sw  bands  ......  nice to  have a  panoramic  display , 2  mhz this time , the  ra17  was 1 mhz  and   28  valves + 20 ish  > in the  radio

OK Graham
 
Thought it was home brew retro.......... I am in that mode and think everbody else is! What do you do at the moment inject a Sig Genny?
 
Have you checked the net or checked out Vincent - QuartzLab etc?
 
Anyway what's that master osc circuit. I build from old RADCOM (pre 1975 when they published real amateur radio) and PW,QST etal. I use modern xtals with no known issues. Well trying to get third overtone for 10m not to chirp is an issue with me at the moment. 
 
OK yes got a stick on its way didn't want to tear up my existing upconverter design. But not sure there is much wrong with the UC approach it works for me. But want to try the direct approach. Do you get much Cross mod and IM products?

The  set  , Marconi  Ocean span 1950's  valve  tx   needs  the  big  rock's  as the  oscillator  pass's   quite a  lot  of  power  via them ...hc6u  are  no  good  , drive level is very low - the ones fitted  are the wired- gold  flashed  ones  , so  cannot  etch  into the  band ...
 
the  gang  want  to  keep  it  standard

Hi
 
If you want to spend a small fortune get them cut. However build a Mixer VXO from El cheapo standard xtals and or old PMR rocks. Then at your next rally buy a couple of Screw together 10xj or FT243 rocks of any frequency and put the El-cheapo xtals inside. And Hey Presto you have Retro rocks.
I have a small all valve 472 tx that uses 6.00 -6.472=0.472 vxo-able a couple of kc/s 12ax7-6am6-6cl6= 4wattso/p. Local QRP rig.
Hope this helps
