Question about Icom IC-V8000

Open Question

Icom ic-v8000 can I use a HM-151 on the IC-V8000?

The HM-133V locks into transmit when I press the PTT. I have a HM-151 (came with an IC-7000), can I use that mic on the IC-V8000 without damaging either the transceiver or the mic?

SOURCE: Icom M710 Transceiver dosen't transmit.

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)
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.

My icom v8000 says off when I transmit how do I fix this

This sounds very much to me like a power supply problem.
If I understand your question correctly, the radio will turn on but when transmitting it shuts itself shuts off. This is usually caused by a poor connection to your battery. Although it is possible to show 12v using a voltmeter, there may not be enough connection when putting the circuit under load. (25 watts is a considerable load)

I would inspect both positive and negative connections (pay particular attention to the crimped lugs) , clean and lubricate them and give it another shot.

Here is a link to Trojan battery explaining in detail the importance of clean battery terminals.

Hope this helps you out.

Display says OFF

You are on a portion of the 2 meter band that the radio does not allow you to transmit on. You need to get within the legal band portion and transmit there. The IC-V8000 only transmits between 144.000mHz and 148.000mHz. You likely have the radio outside of that range.
