Remove CPU/dsp unit by unscrewing two silver screws holding it down (the silver box on the top of the radio with copper taped sides) and pull up. 2. Locate four shift registers and bank of diodes - shift registers are 4094's. There are two next to each other and then a couple more. We'll call the two stacked the "left" ones 3. The "left" shift register if looking from the front of the radio is the target. 4. Locate bank of SMT diodes (silver with "K" on top on one side) in front of the target shift register. They are in two columns, "left" and "right" 5. Unsolder one side of the second diode from the front on the left and lift up one side (or remove, slip to the side, whatever turns you on) I've uploaded a new photo with a picture as well (tv_mars.jpg) with both mods clearly illustrated.

To satisfy my desire for confirmation, I wrote to Icom, and received the following reply. ---Michael, AE6QC ============== You are correct. The IC-7000, with the supplied microphone, does not support real time DTMF. So far, none of Icom's HF radios have had the option for direct DTMF entry with their supplied microphones. If you wish to have the ability to enter DTMF codes directly from the microphone, real time, you will need to use the HM154T microphone. This is the same way that you could use DTMF on the 706 series radios or any of our other current HF radios.

IC-7000 owners requiring DTMF keysending should connect the HM-154T to the radio instead of the stock HM-151. The HM-154T will not support the mic-based control functions of the HM-151 supplied with the IC-7000. It is our fervent hope that this will put the DTMF thread to rest (at least for a while.) Well, mostly. Are the schematics for the HM-151 and the HM-154T available? It might be possible to add the functionality of the one to the other, with that information. 73, doug ========================================================================= Date: Fri, 9 Dec 2005 14:53:04 -0600 From: "Stephen Hicks, N5AC" Subject: RE: MARS MOD...

To all, I have uploaded a high resolution picture of the shift registers/diodes with both the TVRO and MARS mods detailed, per the information provided to us by Stephen, N5AC. I put the full file in the files section, and uploaded the picture to the photo section of this group. The file name is TVRO-MARS_MOD.jpg. I did not put the "credit" line in the file, as I do not know if Stephen wants it in there. Stephen, if you want a credit line in the photo, I will be more than happy to add it. We all thank you for your experimentation and success! Just remember that the DSP/CPU unit must be removed in order to expose the board as seen in the photo. My unit required that three silver screws be removed. One note to all, I have modded almost every rig I own. I have not caused any disasters, but I worry every time I do a mod. These diodes are 1 mm in size. If you have any doubts about being able to do these mods, please consider having a service technician do them for you. As far as whether to just "raise a leg" of the diode or remove it, I think you have to be very good just to raise a leg. I'm able to do it occasionally, but I tend to remove them, put them on a small piece of Scotch tape, and put the tape with the diode somewhere in the supplied Owners manual, should it ever need to be reversed.

I generally loose anything that is not tied down, so I generally unsolder the device and then scoot it to the side, leaving one pad soldered and the other resting on a part of the silk screen that is non-conducting. Not that the diodes are polarized and are marked. Be sure if you decide to reinstall, etc. that you put it in the right direction.

The diodes actually have very small flat leads sticking out under the device. They are very small and you can only see them once the device is up off the board. If you are good at soldering and have a decent low wattage iron, it should be no problem. Do not force anything as you can tear a pad off of the PCB. Although not probably a recommended method, I generally take the iron and hit either side of the diode back and forth till the device and the board are hot enough for the solder on one side to stay liquid as I move to the other side. You have to move fast and be careful, but I use this method a lot on SMT microwave boards and it works for me.

Yup that would be me, the fan mod guy its posted at mods.dk and also here in the files section of the forum Here it is in a nutshell.... Pin 3 of the tuner control is 12v+, run a lead from pin 3 to the red wire of the fan with a 2W 100ohm resistor in between Runs the fan constantly at 0.12mA, and when the temp control circuit should it ever kick in will increase the rpm of the fan by bringing it up to .15mA then once the temp circuit shuts down, the fan returns to 'normal' duty mode at 0.12mA I went into a ton of detail in the post at mods.dk, and there are 3 additional posts with temp readings on the outside suface of the unit using a baby thermometor digitial. before fan mod, everything was around 103-106+ F, after the mod, my rig runs around 85 - 93'ish F and rarely do I ever see the temp circuit kick in. What about an autotuner you say?.... Well my LDG At-100 Pro has no complaints what so ever about the fan mod and being connected to the tuner control. Works perfectly.

You are both missing the point. If the TCXO is spec'd to run at (say) 120F, and the temperature inside the radio next to the TCXO is (say) 130F, there is NO WAY the TCXO will run within spec. A TCXO will always have a minimum and maximum ambient temperature that it will be able to maintain spec within. So, I'll ask again: Was this considered in the fan modification? By the way, I will be at ICOM this afternoon to pick up two ID-800 radios that ICOM is loaning me for software development, and I will ask them what they think of this modification. -- Dean ========================================================================== Date: Thu, 06 Apr 2006 13:02:44 -0700 From: Ken Arck Subject: Re: Couple of questions.

Being designed as a mobile rig, surely the low and high ranges must be at least what would be encountered in a vehicle, plus any heat generated by the radio itself. Icom specs the operational range of the radio as +14 F to +140 F. At the minimum, the TCXO would maintain freq within this range. You're WAAAY overthinking the issue of the fan running continuously if you think the TXCO would fall out of this range simply due to the fan mod.
