Hi,here is a manual....

SOURCE: VHF transmit power
Hi, It is not typical but neither is there a problem with the radio. Transmit Power output is loosely dependent on the: 1. Frequency or channel you are transmitting. Normally, Marine Band VHF are calibrated for max (25 in your radio) at Ch16 or 156.800Mhz; 2. If the SWR of the antenna is not a flat 1.0, power tends to go down; 3. After some time, the TX side of the radio needs to be re-calibrated; 4. Power Supply - some radios will push max output only when powered with 13.8 and tends to go down when used with 12 volts. Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.

As advised, reset to factory settings. Then re-entered custom settings as required. Seems OK now. Many thanks.

SOURCE: I have an Icom VHF that was hooked up reverse polarity on 12v.
They likely replaced just about every diode and possibly the main circuit board. The tech should be willing to tell you exactly what work was done, and many return the replaced parts.

Hi mesquaukee,
Are you trying to connect the SCS PTC-IIpro to an Icom M710 (or M700pro) marine transceiver? If you do kindly refer on the information below:
The audio connections are the same as the PTC-II/IIe, the radio-control connection is specific to the IIpro.
Audio connections:
PTC-IIpro Audio Icom M710 ACC(1)
(8-pin SCS DIN) (8-pin Icom DIN)
---------------- -----------------
(Tx audio) Pin 1----(vio)-----Pin 4 (Mod)
(Rx audio) Pin 4----(grn)-----Pin 5 (AF out)
(PTT) Pin 3----(yel)-----Pin 3 (PTT in)
(Gnd) Pin 2----(wht)-----Pin 2 (ground)
(+12V) Pin 5----(blu)-----Pin 7 (12V out- see note)
Shell---(shield)---Shell
Notes:
1. The colors shown above are for the pigtail cable supplied with the PTC-IIpro. Check the colors with an ohmmeter, errors are possible.
2. The German-style DIN connector has a different physical pin geometry, and is not interchaneable with the US-style DIN connector used by Icom. Label the cable ends to avoid any confusion over which end goes where.
3. The PTC-IIpro has provision for an alternate 12V input on its HF audio connector. This provides a convenient way to connect power to the modem, but if the cable is particularly long then this could be a source of RF interference. Consider a separate power connection for long cables.
Remote Control:
Remote frequency-control is optional, but highly recommended when a PTC-IIpro modem is used with an Icom M710/M700pro transceiver. There are two options for connecting remote control to the radio, the recommended connection is to use the M710's 9-pin "Remote" connector (supported from Airmail ver 3.0.857 onwards). As an alternative, the 1/8" mini-phone "Clone" jack can be used, see "option 2" below.
PTC-IIpro "Control" ICOM 710 "Remote"
(13-pin DIN) (DB-9P 9-pin male)
----------- --------------
Pin 3 (yellow) -------- NMI+ 5
Pin 8 (red) ----------- NMO+ 7
Pin 13 (orange) ---+--- NMI- 6 (see note)
+--- GND 9
Shell ----(shield)----- Shell
Note: Add a jumper between pin 6 and 9 on the 9-pin connector, so that the (orange) ground wire connects to both pins. Also make sure that unused wires are carefully insulated, short-circuits can damage the radio or modem.
Radio Settings:
In order to use the NMEA interface, it must first be selected using the front-panel "Set Mode" functions (turn power on while holding down the "Func" and "1" buttons-- or "Ent" and "1" for the 700 pro). Select the "REMT-IF" (remote interface) setting and change it "d-Sub" (or "RS-232" on some models). Also check that the "REMT-ID" setting matches Airmail's "AIcom Addr" setting).
AirMail Options Settings:
Modem (TNC) connection:
Modem type: PTC-IIpro
Comm port: COM1 or as appropriate
Baud rate: 38400 or 57600
Show link messages: no check
Ignore CTS: no check
Audio Tones:
Center Frequency: 1500
Check "USB"
Check "Marine (FSK dial=center)"
Amplitudes: as appropriate, start with 130/170
Radio connection:
Check "Direct using PTC-II control port"
RS-232: Checked (this is important!)
Radio type: "Icom-M710" (select appropriate model)
Baud: 4800
Icom Addr (hex): 01 for M710, 02 for M700pro, or 03 for M710RT (must match radio's REMT-ID setting)
Dial offset: 00
Note: Entering the radio modes with the "Modes" button is no longer required.
Hope it helps.
Thank you for using Fixya.

Your older nodel VHF is most likely no transmitting due to a defective MIC. This is a common issue with radios that receive but not transmit. It is not the antenna.

Usually answered in minutes!
the correct answer is call ICOM
I have plies of ham ICOM gear here.
am Extra licensed. 2meter and HF big time.
some times a radio can be upgraded to features like that and only Icom can help.
if you learn now please share it.
ok.
marine safety is great thing, as is SOS/mayday beacons.
one more is SAT PHONE ! in water poof bag.
like what the guy on movie didn't have

I'M So old I used to fix LORAN in the navy.
and most else to..shipboard (ECM and more)
I'd say off hand a VHF that has linked GPS data. fully automatic.
or wait for the new GPS to come on line....?
