Even in this price point Icom is using a 1 hz synthesizer. Of course this type of button may not hold up in years to come as air reacts to the plastic/rubber, and also the printing on these type of buttons can have a tendency to wear off.īut I have not seen any groans on this over the years either (at time of writing). Rubber pushbuttons have been used, that seems to be the norm with ICOM these days. The optional DSP is the same board that goes in other ICOM Amateur sets, so it's using the old AF type of DSP stuff. The set features 'Twin PBT' (Pass Band Band Tuning) as used in many of Icom's Amateur Transceivers. Tuning knob even uses a optical encoder, so no cheap stuff here.

But overall it's a great tabletop set for the money even on the used market. More on the 'Sync' topic from others below. The Sync detector is the other real stinker but Kiwa has a mild modification for that as well that sort of helps on this too (or not). I have tested this in 2 steps, including before and after digital recordings, so I have experience with both of the Kiwa audio mods.

Important: One should have BOTH Kiwa audio mods done to help the audio, but at LEAST the 'High Fidelity Audio Filter Upgrade' one. However, from my own 'before and after testing' this does NOT totally cure the problem either (when compared to the AOR AR7030's super good audio, the old Kenwood R-1000 does much better in the 12+ Khz bandwidth even after the mods). One can improve on this with 2 separate internal audio modifications that can be done by Kiwa Electronics in MN USA. This 'cloudy audio' ill is detected more so in the AM mode 'super-wide' 15 Khz bandwidth. Continued ICOM's trait of poor audio, but it's not as bad as the old IC-R71 'Distortion Beast'.

Convert Icom trail version to full software.įor most samples this will be a unregulated linear transformer, but in mid 2009 this was changed to a switching type supply (see below for more information on this subject). The Icom IC-7000 is an excellent SW and MW DX receiver. USA versions include a 'Floor Brick' AC power supply.Īnother Icom Gem: The IC-7000 © Bjarne Mjelde October 2006. This allows one to catch the 6 Meter amateur band as well. Frequency coverage is from 30 hz right to 60 MHz. (N9EWO photo) Discontinued Receiver Icom's IC-R75 tabletop HF communications receiver came into the market back in 1999 and was taken out of production in late 2015. Came onto the market in 1999, production ended in late 2015. Once the audio issues are fixed (Kiwa mods), is a nice tabletop set. Later samples (US versions marked as the IC-R75-12 and IC-R75-22 on it's outer box sticker) no longer offered the 'Sync' function. Also to my ears the audio quality in AM mode is fair at best even with a external speaker in use (can be improved, see text below).

Many versions include the 'Sync' circuit that is really worthless.
