We have found it difficult to do ra.nytiiieze ezcopt the brush fires that keep breEalclxaG out all arourd us. We finally got everything under control enough to draw up this description have ñ3.ae. for special handling of of the agrrn,r:4r,eaexni:pta Alerta "l'.A,$i1 traf Tie. filt. As stated to I~tr. Sharpe we believe the reli.ability of the S:R1D in handling these *zessaTes *aill be very high. The cirreumst,an.oes under which it maybe precluded fron doing so will ro doubt bo peculiar. Unlßscs tho circt.:rnata.:ce to failure of the ,SÁR.1.D cnu.ipr:sant itself, it is highly likely tl:afi, any other automatic c+rna.eemcnt would be equally incapable of poaÁorm{n,g under the cano conditions. We doeirled teat chat uus required vus ananual override of the SÁß:,D and tìinre:'ore discarded the fuïi.y uutesmatic design already completed.

We have chosen the ° carriage return function or the alerts -teseu,?o turning as the one most unlikely to be repouten four Mew under other circumstances. This Could replace the previously, agreed lino food-carriage return functions to avoid the need 'or a modification o^ the nodule to rotognido two different functions. You trill note that the ii controlled radio circuits to LTC be busied out for the ii erto message OTC-LTC to avoid the 'ß.',D choosing u free ra-?to circuit rather than the e b10 circuit, with the possibility that the PnG on the relie circuit could go into repetition and delay the mess l° .
