vanishing convoy Htdr. contacts
Hi, I've had that before also, and sometimes a very quick change of the hydrophone officer fixes it.
Also the Hydrophone (early ones anyway) dont s
'see' the full 360 degrees around your Uboat, and don't pick up contacts behind you - or not nerarly so weel anyway. Normally a change of heading towrds the contacts position also fixes the problem. Fog banks won't stop the Hydr working... , but a sudden increase in speed (above speed '2), can also eliminate the contacts in some instances... I have found much reduced Hydr range when using speed '3', for example unless contact is almost directly in front of you.
Hope that's useful ?
