IC-7200 MARS Mod Needed

I picked up an IC-7200 the other day, and I'm very happy with it. However, I need to open it up so I can use it with my Ten Tec 2 meter transverter which requires me to go to 32 Mc to cover the whole 2 meter band. Being I like to run 2 meter AM on 146.520, this is important to me.

None of the mods I've found on the internet seem to apply to my new production unit. For example, D49 which some have mentioned as needing to be removed for opening up the TX is already gone.

Does anyone have any information on what mod is needed for these new production IC 7200s? I'd sure appreciate it if you would let me know if you do!

Thanks and 73

Steve

I'm not sure my friend. I noticed it when I went past the band edge of 20 metres with no tone or anything. So I dialed to cb land and she transmitted. I only had it for maybe 6 weeks before I got rid of it.

I see.
Any reason in particular you didn't like the radio?
I like mine, but it's the only hf rig I've ever owned, so nothing to compare it to.

Great radio, a tad bit heavy and big for HF mobile. Only reason for getting rid of it. I traded it for an IC-7000 with tuner. That move free'd up space in my pick up. 2 radios down to one.

If your not feeling the mojo to do the mars mod you can always change the crystal in the transverter. Assuming it's the same Ten Tec kit I put together you can, or used to be able to, order a crystal from Jan Crystal to lower the input freq of the transverter to get the full 2 meter band coverage.

Thanks! I just picked up a used 7200 that was part of a complete station. I bought a new one when they first came out. I sorta missed it, so when this deal came along I jumped on it, I never clipped that one. I'll probably clip this one this winter.

  • @ ButtFuzz:
    on the connector with the green wire, if you short that to a nearby black wire, the power supply will turn on. (for use as a bench supply or whatever)
  • @ ButtFuzz:
    And IIRC, the purple wire is -12VDC, but that is from memory and it does not serve.
  • @ ButtFuzz:
    So if you need, say, 7v, connect + to the Yellow wire and - to the Red wire.
  • @ ButtFuzz:
    or or you need 9v connect + to the yellow wire and - to the orange wire. note: not all PSU's have the orange wire nowadays, as many manufactures had the voltage regulation on the motherboard, and all the power supply gives is 12 vdc
  • @ BJ radionut:
    Thanks ROB will check it out!~!! got to clean the work bench a little make room for that big case :)
