Receive standby current

Icom specs say 1.3A on receive squelched and 1.6A full volume.

I checked mine. I got 1.36A two minutes after power up with default settings on 2m FM. Full volume (painful) was

1.52A. I found I could save about 40mA by reducing "LCD Bright" to minimum (and still read the display) and

another 40mA by turning off the switch backlighting. The readings were a little tough to validate because the fan is

variable speed and can affect the readings by more than 100mA.

These numbers seem consistent with the published Icom specs. It's not exactly milliamps but it's still 500mA less

than the IC-706MKIIG specs.

Icom IC-7000 Frequently Asked Questions (FAQ)

How do I…?

How do I hook a monitor to my IC-7000?

The IC-7000 uses a 1/8” mono mini jack to provide composite video out. Any monitor, TV or VCR that

supports composite video input (yellow RCA jack) can be used as a display. Although the 1/8” mini jack

is small, it’s not a standard video connector. Radio Shack offers a 6 foot cable (Catalog #: 42-2444) for

only a few dollars that has a 1/8” mini plug to RCA plug and will connect the IC-7000 directly to a

standard composite monitor/TV.

It is also possible to use an adapter to convert the 1/8” mini jack to an RCA to allow the use of a standard

RCA cable. Rigid adapters should be used with caution because the jack can be pulled off the main board

if too much torque is applied.

“To use with a standard computer monitor, it is necessary to convert the composite video to RGB video

with a device like the KWorld TV Box 1680ex

.

I use this one and it works ok but the above is better: /mpd/

How do I use a Bluetooth headset with my IC-7000?

“Works great. See link below from K7SFN. /projects/”

How do I connect more than one CI-V device to my IC-7000?

The Icom CI-V interface is a serial bus design. This allows more than one device to be connected to the

radio CI-V interface (amplifier, antenna switch, SteppIR antenna, additional radios, etc.). “To connect

these devices get a flexible adapter like the Radio Shack 42-2437 or even a three-way adapter like the

Radio Shack 42-2458”.

How do I get better transmitted audio?

The IC-7000 was designed as a mobile radio and the microphone was intended to be used in high noise

environments. Although the Heil microphones and W2IMY equalizers provide excellent audio, many

people want to maintain the functionality of the stock microphone and get better audio without the

expense of these options. AB5N has created a modification for the stock microphone at

/ that creates a “hotter” microphone and higher quality audio. There is also a

microphone modification posted at /.

The IC-7000 has two microphone jacks but the Icom manual specifically states that only one microphone

should be used at a time. This is likely because both microphones would be hot at the same time. Some

have suggested a mute switch (disabling the mike element) in the stock microphone. This would allow

the stock microphone to be used as a “remote control” in one mike jack with a headset in the second mike

jack.

How do I use my IC-7000 on 60m?

Page 40 of the IC-7000 manual provides information on 60m operation and is quoted below.

Icom IC-7000 Frequently Asked Questions (FAQ)

To assist you in operating the 5 MHz band correctly within the rules specified by the FCC, transmission is

impossible on any 5 MHz band frequency other than the 5 frequencies indicated in the table below.

IC-7000 Display FCC Channel

Frequency* Center Frequency*

5.33050 MHz 5.33200 MHz

5.34650 MHz 5.34800 MHz

5.36650 MHz 5.36800 MHz

5.37150 MHz 5.37300 MHz

5.40350 MHz 5.40500 MHz

NOTE: We recommend that you store these frequencies, mode and filter settings into the memory

channel for easy recall.

*The channel center frequencies that are specified by the FCC, show the center frequency of their

passband. However, the IC-7000 displays carrier point frequency, so set 1.5 kHz below from FCC

channel center frequency.

How do I get full power output when transmitting?

The IC-7000 was designed to deliver full power output at 13.8 volts. This is the voltage provided by most

power supplies and the alternator output of a vehicle. The voltage table at the beginning of this FAQ

shows output as voltage drops. When using the radio from a battery it is necessary to use the largest

possible power cabling and a battery voltage booster to maintain the 13.8 volts required for maximum

output.

I use my IC7000 on CW almost exclusively, and I operate ONLY mobile. I use the N8XJK booster

/

with no problems at all. For a while I used it with the RF sensing, but no

longer not because of any performance problems, but because when the engine is running I don't

need the booster, and when in receive I don't hear any noise problems from the booster, so I decided to so

away with the additional wiring needed to use the RF Sensing.

“I will ad that the MFJ-4416 voltage booster has helped greatly when the vehicle isn't running. This radio

and many other mobiles do not Tx full output power on less than 13+ volts. So either get a battery voltage

booster or keep the vehicle running.”

How do I use my radio in VOX mode?

“Two things two check. You are in a voice mode and you have turned VOX on. I just tried it and it works

with the stock 151 microphone. Be sure the word VOX shows up on your display.”

N4LQ>

“Turn the VOX Gain up reasonably high, and turn the Anti-VOX as low as you can with out the speaker

triggering the VOX. My 7000 works great with stock microphone in VOX mode.”

Icom IC-7000 Frequently Asked Questions (FAQ)

How do I access the CW/Voice memory keyer?

The CW and voice keyer options are accessible through the menu. When using the keyers via menu, it is

not possible to access other features or the popular multimeter screen. There is a simple resistor network

with switches shown in the manual to allow immediate access to the CW/voice memory keyer.

“I made the device in the photo for solve this problem using the circuit at the 135 Page. I use my 7k for

contesting and expeditions so the voice message function is a powerful help but use it via the menus is

complex. /ea1nt/

How do I use a Turbo Tuner and screwdriver antenna with an IC-7000

On the Turbo Tuner Web site, N2VZ is shipping Turbo Tuners setup for the 7000 AND the software

update for Turbo Tuners that were programmed for 706, to make it a 7000 tuner. He will email you the

update to flash your 706 Turbo Tuner thru the RS232 port on the Turbo Tuner.

/

How do I enter DTMF tones for Echolink/IRLP or repeater control?

The stock IC-7000 microphone has many functions but like the IC-706 family, it can’t generate DTMF

tones. There are two solutions offered by Icom. The first option is the same DTMF microphone used by

the IC-706, the HM-154T.

There are also 4 DTMF memories of up to 24 digits described on page 67-68 of the IC-7000 manual.

This allows recording command/control sequences in these memories. Set Menu Option 38 specifies

which DTMF option appears when F-2 is pressed in the menu.

Can I use my IC-706 accessories with my IC-7000?

Most accessories from Icom and third parties will work directly with the IC-7000. There are a few

exceptions. The Icom remote kit is different for the IC-7000. The body and head bracket are the same

but the remote cable has 10 pins, rather than only 8 pins. The microphones are largely compatible but the

IC-7000 does not have an audio output line in the microphone cable. This could effect some TNC cables

and older Heil headsets. The later Heil headsets have a separate speaker plug. There have also been some

compatibility issues with third-party tuners (LDG and Turbo Tuner) although ROM upgrades are

generally available to address these issues.

Where do I find…?

DC Power connector

“New HF radios from Japan, introduced in the past 5 years operating on 12V DC, like the ICOM IC-7000,

Kenwood TS-480, Yaesu FT-450, Yaesu FT-2000, and the new ICOM entry level radio all use the same

connector, wired the same way.”

Icom IC-7000 Frequently Asked Questions (FAQ)

Monitor

There are too many monitor options available from too many sources to list here. The IC-7000 provides

composite video out. This can be run into most TV sets and VCRs with the appropriate cable (1/8”

monaural mini plug to RCA plug).

Small monitors can often be found on eBay and any place that sells car audio/video. In-dash DVD

players and many navigation systems include a composite video input. There has even been some

discussion that a Toyota Prius instrument panel has an input that could be used for an IC-7000.

Icom uses a 7” Xenarc 700YV monitor in the display they use at hamfairs. This monitor is more than

what is necessary for most users. The rated LCD brightness of 500 cd/m² and contrast ratio of 400:1

crates a nice image. These are the two most important numbers when determining the quality of an LCD

display. Often these numbers are not available and the price is the only indication of the relative monitor

quality.

CI-V computer interfaces for serial and USB

Icom sells the CT-17 interface, which offers 4 CI-V ports and a single DB-9 serial port. There are a

number of less expensive options available on the market in both serial and USB. These are commonly

found on eBay. Radio Shack also has some scanner programming cables that will work.

“I purchased the Radio Shack 20-047 USB Programming Cable & Driver Software today.(the number and

description is right off their label)I followed their directions and connected the USB plug after installing

the driver. It connects at 19,200 bps and has not given one sign of This is faster

and easier than the CT-17.I used a 20 foot stereo extension to get to the ICOM and used the stereo to

mono adapter supplied with the interface to plug in at the radio end of the connection.18 hours later, I am

sure this is the best way to go.”

Interfaces are also available from:

Control software

The IC-7000 is similar to the other Icom HF radios and can use much of the same software written for the

IC-706 family (although the radio address may need to be changed). More software is offering native IC-

7000 support. One of the first and best is Ham Radio Deluxe (HRD) and is available for download at no

cost from /.

Memory programming software

There are a number of packages specifically designed to program the memory channels in the IC-7000.

Icom IC-7000 Frequently Asked Questions (FAQ)

Radio Issues

The IC-7000 runs hot even on receive

There are reports of the IC-7000 running hot despite most of the radio body being cooler than the IC-706.

There are three points in particular that can run warm; the display because of the backlight, the area

behind the speaker where the DSP ICs are heat sinked and the actual heat sink on the back of the radio.

Here is a chart showing relative temperatures of various devices with color displays. The temperatures

below were taken with an infrared thermometer after a 24 hour warm-up period at 71 degrees F with no

transmit.

Icom IC-7000 91°F 33°C

Icom IC-2800 107°F 41°C

Sharp 15” TV/Monitor 85°F 29°C

G2G 5” TFT Portable Monitor 106°F 41°C

Initial 7” Portable DVD Player 85°F 29°C

The display runs about 91°F. The heatsink on the rear runs 99-103°F (in receive). The cooler areas on

the back are 92-96°F. The temperature on the top ranges from 95-109°F. The area directly behind the

speaker is the hottest at 109°F. This is directly over the silver box containing the DSP chips.

The thermometer on the multimeter display shows the rear heatsink temperature. The final output

transistors use this heatsink.

Many users have installed fans over or behind the radio to increase the airflow over the chassis. Care

must be taken with fans in dusty environments. There is also a fan modification published on

.

Strange behavior on transmit (shutting down, resetting, changing frequency, etc.)

This is most commonly a grounding/RFI issue. Make sure the radio and antenna are properly grounded.

If the separation cable is being used, attempt to route it away from RF sources and be sure to use the

screw to attach it to the radio.

Audio feedback during transmit

Check to make sure you don't have the "monitor" turned on. Usually, you just use the monitor when

transmitting digital modes.

• Push SET button (AF gain control knob) upper left hand corner of radio.

• Go to "Set Mode" > OTH > Monitor. Set to OFF

High frequency (8kHz) tone in audio

Very early models of the radio had a noticeable tone at 8kHz. This was not audible through the internal

speaker because the internal speaker is “communications grade”, meaning it has a frequency response

limited to voice frequencies. It was also not audible when using Heil, David Clark and other

7 12/22/2008

Icom IC-7000 Frequently Asked Questions (FAQ)

communications headphones or speakers. It was most obvious when using inexpensive “Walkman” style

hifi headphones which are excellent at reproducing non-voice frequencies.

Icom addressed this within a few months after production began with some capacitor and grounding

changes. This modification should be available at no charge for units in warranty.

Low level hiss in audio

Many radios have a small amount of hiss (white noise) when the volume is set to the minimum value.

This hiss remains at a constant level as the volume is increased and is quickly overwhelmed by signal

audio. The hiss is apparently internally generated. There is no known solution but some users insert

attenuators in the audio line. Since the hiss is a fixed level, it will reduce the hiss level while allowing the

signal level to be increased with additional AF gain.

This audio hiss is very low through the internal speaker because it is “communications grade”, meaning it

has a frequency response limited to voice frequencies. Any external speaker or headphones should also

be designed for communications work, rather than hi-fi, so as to minimize this issue.

S-meter reads low

The IC-7000 S-meter is very accurate but as a mobile unit is calibrated to read accurately with the preamp

enabled.

Changing the transmit audio bandwidth results in poor transmit audio

The Icom IC-7000 supports changing the transmit audio bandwidth. There are three predefined settings

which can be modified. Because it appears the transmit equalization feature was cut, there is no way to

rebalance the audio as the bandwidth is narrowed. This makes the audio quality very poor at narrow

bandwidths. If DX-quality narrow audio is desired, the best solution is a good DX microphone or an

external equalizer like those from W2IHY.
