Radio - novice - finalization of a modem for ZX.

(C) FARAON


   FARAON again welcomes its readers!

   Today I am speaking in a somewhat unusual role for himself - 
I Tell you how to improve your modem. Mounting

modem card shown in Fig. 1.

   First, watch out for the modem. When the source
supply and connected line receiver LED should not
flashes or, especially, light. It is not necessary to load 
CDOS; can play at this time (this does not apply to those who 
have "TURBO 2 ..." - they must be sure to load it). If this 
occur (even rarely), it is necessary to replace the resistors 
R03, R09 and R10 100k at face value. If it does not help - 
Increase denomination resistor R06 to 15-18k.

   In any case, if you have someone with some friends a bad 
konnektrekomenduyu configure the modem with it. 

   There have been cases where, besides the above, had to 
reduce the resistor R08 to 910-820k. In this case, the 
receiving LED initially completely glowing.


   On it I finish. If you have questions - call, explain to.


  P.S. Many thanks to Andrew (497-74-66) for the perfectly 
drawn montazhku modem.
