Radio Good - Mic Bad !  Time owned: 0 to 3 months
I recently bought this transceiver from a UK dealer at a discounted price, so these are my first impressions.

So letís get the gripes out of the way, before moving on to the good stuff..

My first surprise was the weight of the box when it was delivered. This was due to the in-line DC power filter supplied as standard with models for the European market. This thing is mounted in the DC lead near the back of the transceiver and itís huge, weighing about the same as the rig its self and occupying about 1/3 of the size. Why make a transceiver so small and neat when you have to have this lump attached externally?

The audio from the stock microphone is disgusting, the mic gain is insufficient and the compression gain far too great. It is very difficult to get this combo to work at all well. Mic gain has to be set near 100% and Compression gain about 1%. Narrowing the AF bandwidth and rolling it off at 500Hz adds some very unpleasant artefacts, so donít do it. Fortunately AB5N has a mod kit available which fixes this problem, but Icom should be ashamed of this aspect of the design. Itís basically a keypad with the mic element added as an afterthought.

Some other minor points are the high running temperature, which canít be healthy for long term reliability (but time will tell), difficulty in getting audio in to the radio for PSK operation, especially via the data port, as you have to operate the PTT line on that port in order to mute the microphone and enable the data input, using other ports leaves the microphone enabled. Not too great if you wish to use Ham radio Deluxe and CIV PTT control. Another annoyance is the way Icom have configured the external tuner port. If you wish to use a non Icom auto-atu you need to build a 555 timer interface or similar (simple interfaces can upset fan operation and damage the internal switching circuit) so that you can use the front panel tune control to initiate an auto-tune.

HoweverÖÖ.

The receiver is very good; especially the IF DSP and auto notch filters. It is possible to copy weak SSB signals underneath S9 CW transmissions, itís absolutely amazing. The IF filter bandwidths are great and the shift function works well. Even the DSP noise filter is effective. WOW.

The menu system is relatively intuitive and requires relatively few button presses to get to where you want to go.

Its also got lots of extra toys, many of which I may actually use.

My current radio is a Yaesu FT-897D (which cost almost as much by the time I had added extra filters) but this radio is streets ahead.

I would really like to give the Icom IC-7000 a 5 out of 5 but because of the poor mic audio (which I think is inexcusable) so Iíll stick to a 4.
