2510

Is your 2510 slow on agc??? does it take 3 frames at 1200b for the
rx to come up to sensitivity?? do you want to make the rit a rtit (rxtxit)
then maybe these mods will help you, they also may apply for the newer 
versions of this radio, you who have the 2600 may be able to use them.
mod 1.
 speed up agc, this is easy, just pull out the transistor q111 and you have
fast agc, if you need to select slow agc then put a switch from the collector
to emitter and pull the collector pad to ground for slow agc 
mod 2.
 make the tx and rx both responde to the rit control and reduce the amount
of frequency change for the control.
this one requires that you locate the rit control and remove the following:
r 802  a 1k resistor in series with the rit pot
the rx 8v line that goes to high side of pot, remove and put aside, you
will need it for power to nb switch and rf gain control.
now remove the subassembly b801 pb-120 and remove r802. cut pc land between
high side of vr802 and r 801 you will now solder the rx 8v line to the
freed side of r 801.
