Mods for the ARE/AEA HamLink:

1. If you are using an ARE ARE-60, chances are you have an old version
   of the firmware. The latest version is Ver. 4.0 - (2 EPROMS) Call
   AEA (Hadley Allhands) for more info on how to obtain the new firmware.

2. Change R14 from 130K to 248K if you have Touch Tone falsing problems.
   The tone detection was much too fast and would cause HamLink to false.
   In the middle of a QSO, often the radio would QSY some where else. The
   248K resistor solved this problem. Hamlink still decodes tone very fast
   (setting #6 or slower on the Alinco DJ-580) Careful when changing this
   resistor as the foil near the 8870 IC comes up from the board very easily.

3. Older units used a 13K resistor at R10 to determine confirmation beep level.
   It was much too loud so they put in a 100K resistor in all their newer
   units. This was still too loud for me so I replaced it with a 1M 10 turn
   pot. This allows me to adjust the level to my taste.

4. If you are using HamLink with a Yaesu FT-1000 or FT-990 you might have
   problems getting the unit to communicate with the radio. ( Via the CAT
   port). If this is the case, place a 2.7K resistor between pins 1 and 2
   on the CAT DIN connector (serial date + ground).

5. I moved the internal programming jumper to a toggle switch on the back
   panel. Same for the reset switch. (Drilled 2 holes on back panel).
   Brought out an extension plug from the internal RJ-11 jack with a double
   female connector. With this arrangement, I don't have to open the HamLink
   every time I want to program the unit.

6. Bug that remains; #71# - pin 9 on the D25 connector should go high for
   100 mS after the command is received and does not. All other ON-OFF
   functions work fine. AEA was made aware of the problem in June, perhaps
   there has been a fix since.
