Note from sysop:  The Furuno 1502 is much the same as the 1503. You need the "telex" kit from Furuno.  

 

Shea Weston and Marty Kirk are two marine electronics dealers that have done a number of Furuno installations.  Marty is generally regarded as the Furuno guru.  Contact information for Shea and Marty is on the opening page of the www.sailmail.com website.

 

 

 

 

 

 

 

Thanks to Bob McGaffin for this application note on the Furuno 1503.

 

First of all I would like to thank Farallon Electronics for providing

information on the 1502, Al Meunier of Miller Marine in Jacksonville, FL

who was helpful in installing the modem on the 1503 and of course,

SailMail, for making the whole thing worthwhile.

 

Now to the installation. Like the 1502, the Remote 'A' package 

must be installed. Both items are easy for the average

electronics hobbyist with the most difficult portion being the

reinstallation of the weather gasket on the case. A professional should

be able to do it in about 1.5 hours. The DIN plug is wired as per the

1502 fact sheet from Farallon. 

 

 

If you use the original SCS PTC-II (no suffix), you will need to remove R20 to get sufficiently high audio output levels to drive the Furuno.  

If you are using the newer SCS PTC-IIe or SCS PTC-IIpro, no modifications are necessary to the SCS Pactor-modems.

 

 

Internal program changes to the 1503 are as follows:

9908(TELEX enable) from 2 to 0

9909(TELEX RX bandwidth)from 0 to 1 (this changes bandwidth to narrow from

wide)

9903(TX frequency) from 1 to 0 (this enables you to access transmit

frequencies directly from the keyboard instead of programming them into

a channel and then recalling that channel. This change is optional.

How do you access these channels which are normally not user changeable?

While holding the CH button down turn on the radio. This enters you into

the channel section. Release the button and then select channel 9999

using the FREQ/CH knob. Momentarily depress the CH button, enter 1503

(1502 on the FS 1502) on the keypad and the push the ENT button. Using

the FREQ/CH knob, select the above channels. Enter changes using the CH

button, keypad enter the change and then depress the ENT button. When

complete, turn the radio off which will enable the changes.

Telex (J2B) is now enabled and you are able to use center frequencies.

It all works like a champ. The radio has a very small footprint, is

weather proof, and comes with all cabling to the tuner. This at a very

attractive price compared to the competition.
