These were just a few ramblings and off-the-cuff observations. I did neglect to explain what CW and CW Reverse modes do. So that oversight, I shall correct now.

Actually, at this stage of my learning processes, it would be wrong to call my article a “Review”. These were just a few ramblings and off-the-cuff observations. I did neglect to explain what CW and CW Reverse modes do. So that oversight, I shall correct now. CW, or, Carrier Wave, works similarly to the way sidebands work, although in the case of CW there is a modulated carrier wave, whereas with SSB (Single Sideband),there is no carrier wave at all.

Thank you for an interesting review. I first heard about the Icom IC-r30 in October last year when a friend of mine mentioned a fully featured hand-held receiver had been available for some time of excellent quality with an excellent feature set. I was anxious to find out more so I asked about and it didn’t take me long to discover that the Icom IC-R30 was already very well regarded and a star in its own right when it comes to handheld receivers which I had little regard for until this time.

How Icom managed to get anything extra into such a small body is beyond me but they managed and thus one can easily tune to and send to memory any frequency on that band. The lipstick itself can be toggled on and off so the ability to isolate the lipstick and use a dedicated AM Broadcast antenna loop for example awaits the curious. Internal speakers of such small devices are usually tinny and unpleasant to listen to, this isn’t the case with the Icom IC-R30 which has one of the best sounding speakers for a device of this size I have ever heard. The volume by default is controlled by a pair of up/down buttons on the left-hand side of the radio, I say default because this can be changed. The dial on the tip of the radio can be toggled with the up/down pair of buttons, a neat arrangement as I have already discovered. Some times one might prefer to use up/down button tuning rather than the dial to move between frequencies or memory’s, its all dependent on what you are looking for. If held down when the buttons are in tuning mode the radio races through the frequencies at 2000 spots a second, that’s moving so thank Goodness one can change the frequency step easily down to a fine 10HZ. > On 6 Jan 2020, at 8:36 am, Gordon Smith wrote: > > Good evening everybody. > > You may remember Dane writing on list about this device some time ago.
