Sb: 110, 112, 1200 MODS SAME!
Hello FELLOW Packeteers! I just got off the phone with Matt from Alinco!
I have been asked if the 9600 baud Mod that I posted would also work for the
110. YES IT WILL! The 110, 112 and 1200 radios are identical except for
the power output of the 1200 (25-watts high power compared to the 45-watts of
the 110 and 112!) and the 112 has a LCD display to replace the piece of junk
one on the 110! Also, if you want to have more power in the 1200, you can buy
the 100/112 PA Board (45-watts) for $65.00 from Alinco. It also requires
buying 4 high power switching diodes for $20.00 from Alinco. $85.00 for
20-watts?...Doesn't sound like a good investment to me. Don't forget the time
involved with doing this mod. I discourage the use of HIGH POWER and have
posted bulletins on this subject! Never the less, I feel obligated to pass
this info on to you, I am not the U.S. Government, I will NOT keep things
from you! To follow is the 9600 baud Mod I received from Alinco. Alinco
warns that the Warranty is void if this Mod is performed! KA1BOY has been
great enough to try this Mod and says it works great for 1200 baud as well
as 9600 baud! From all of us to you, THANK YOU BARRY! One point to remember,
you will not be able to use the radio for voice. This mod uses the Mic
Connector...
TRANSMITTER
1. Remove R-31
2. Remove C-40 (save this part, it is to be reused!)
3. Connect one leg of C-40 to PIN 7 of the VCO Board
4. Connect a jumper from the free leg of C-40 to the HOT end of C-35
The MIC input is now connected DIRECTLY to the VCO!
RECEIVER
1. Disconnect the PINK wire connected to the MIC connector and the PC Board
from the PC Board
2. Reconnect the PINK wire to PIN 2 on the IF Board connector
This eliminates the low pass filtering on the discriminator!
That is it to the MOD for the 110, 112, and the 1200! Remember, you now use
the MIC Connector For inputting 9600 baud and it WILL work for 1200 baud!
A special note to all SYSOPS out there...Buy this radio and do this MOD! It
will allow users to set their TXDelay down to a lower setting giving the
channel MORE throughput! USERS, make a DONATION to your SYSOPS so they can
help make the system YOU are using, BETTER! We must all do our part to help!
I would like to hear from all of you that tries this MOD!
I GIVE PARTIAL CREDIT TO BARRY, KA1BOY, FOR HIS INPUT ON THIS MODIFICATION!!!
