IC-7100 MARS/CAP Modification

IC-7100 MARS/CAP Modification

Remove the following diodes to open the referenced frequency ranges.

In the IC- 7100 the radio frequency range can be opened in various configurations. The chart below describes four radio frequency range configurations and the specific diode(s) that enable that configuration. Select only one of the four configurations.

Note Frequency range and specifications cannot be guaranteed after modification

ICOM IC-7100 Why Should I buy

I have an IC-7100. All of those 45 aurora contacts made on 17 March were made using it.

I am asked would I recommend it. Well, yes, if you know what you are letting yourself in for.

Plus features are many - small size of the control unit, nifty touch screen controls, reasonable price, RF DSP, 4m for Europe, good frequency stability for data modes, USB lead to PC allowing direct audio in/out for data, DStar, coverage up to 70cms, ....

The snags I have experienced and my solutions are - low output powers on SSB (needs separate microphone with compressor), "clicking noise" (not a big thing, I am ignoring it), RF getting back into the control cable (use a short screened ethernet cable CAT6 or higher), deep cut on AGC a problem with QRN (electric fence problem in my case, turn AGC off).

ICOM 7100 reveiw

Belive it or not the 7000 , 7100, and 7300 are all the same rigs , just with some tweaking and the addition of a crappie monochrome display ( why did they think we wanted that ?) And dstar ( for a lot of places the only way to do dstar is an additional 400+ dollars for dongles) then they put in a desk based body with color screen and waterfall.

I have a 7000 love the thing to death nice color screen with all the most used buttons immediately on either side of the display, it very covent and intuitive , they really made a mess of a great rig when they did the 7100.

I have known a lot of pigs and lipstick doesn't help, same deal with the 51a and 5100a cheap monochrome display that is gray on gray they don't have the contrast ability to make the text black with a grey background and what kind of a bone head move the 5100a was with a 600 buck rig that everything you need like Radio Mounts and such is an expensive option, back on the rig your thinking of I would actually say save your bucks.

[icom7100] linking to D-Star reflector

instruction manual is huge, but...

1. Press the DR button and scroll to find your local repeater.

2.  Press the TO entry on the touchscreen.  Press "Your Call Sign".  Press the up or down arrows to select "Unlink Repeater" to cancel any existing link.  Press the PTT switch on your microphone to execute this.

3.  Press the up or down arrows to chooset a reflector and press the entry select it  Press the PTT.  You will get a voice confirmation.

4,  Again press the TO entry and choose "Use Repeater" and press PTT.  You can now communicate with the reflector..

5.  To unlink, repeat step 2.

Note that you can also access the repeater status and echo test functions from the "Your Call Sign" screens.

Icom IC-7100 expanded frequency mod

I am looking at the document Icom produced for what they call the 'expanded frequency mod'. This is the mod concerning diodes D6315, D6316 and D6310. If removing diode D6316 it lists these as opening the 'desired frequency band':

1.6-54MHz

68-74.7999MHz

118-174MHz

400-470MHz

Icom IC-7100 Unboxing

Icom IC-7000's started arriving at all Ham Radio Outlet locations this week, so I took the opportunity to stop in and pick one up. This is the first mobile HF rig with D-Star Capability, allowing a user to use DV mode on the HF bands like on the Icom IC-9100. This radio further establishes Icom's new paradigm for how users interact with D-Star by including GPS enabled "Near Repeater" functionality, full D-Star Repeater Lists, and the list of all D-PLUS Reflector nodes.

ICOM IC-7100 programming banks

I am new to the IC-7100, and the CS 7100 Cloning Program. I have used the program a couple times in the last few days updating stuff on my radio, and all is OK so far except programing the Memory Channels. It list B01 - B99, C01-C99, D01-D99, and E01-E99 in the program. I put all the analog 2m repeaters in the A bank, and was going to put 440 in B, and 6m in C bank, but after putting the in a 440 repeater in one of the B slots, it did not load into the radio.

Are these supposed to work like the A bank? These are the Memory Channels, not the Digital Repeater list section.

[Icom_IC-7100] Low power output on ssb

A number of users have commented that the average power output of the IC-7100 on SSB, as measured on a moving coil power meter appears low compared with other transceivers. Having made some bench measurements it would appear that this is not so much a fault but rather a result of the very effective ALC on the radio that prevents it being overdriven. A correctly driven SSB transmitter should show the following approx power measurements :
                         Measured on moving coil meter              Measured on PEP reading meter                   Measured on Oscilloscope

Single Tone input                                   100W                        100W                              100W (peak)
Two tone input                                        40W                         100W                              100W (peak)
Speech input                                       12-20W                        100W                              100W (peak)

The reason for the lower reading on the moving coil meter is due to a number of factors including the inherent inability of this type of meter to follow a rapidly changing speech waveform.

Only a true PEP meter or oscilloscope will give a true indication of PEP, cheap wattmeters with a supposed PEP indication often have no more than a capacitor switched across the meter which again will not give a correct power indication.

A no holds barred, cage match between the Icom IC-7000 vs the IC-7100. See how these two great mobile HF/VHF/UHF radios stack up beside each other in an unscripted competition

IC-7100 - Remote

The latest HF/VHF/UHF rig from ICOM are supported by Remoterig. You get full remote functionality from the control panel and the feeling is exactly as if you use them locally. It’s one of the simplest rig to setup and come on the air with. No special cables needed, just connect the RJ45:s and setup the parameters in the boxes. The performance of the radio is comparable with much more expesive earlier models. This setup is going to be a Killer, believe me.

The picture below show my control panel when visiting our relatives 1500 km from home. RRC with WiFi and a Huawei 4G/LTE router with Wifi in the kitchen window is all needed. I got full control over my remote HF-station and are able to chat with the guys at home on 2m.  (4G/LTE gave 20-40 Mbit and 36 ms pingtime)
