From page 43 of the Icom IC-7300 manual (http://www.icomamerica.com/en/downloads/DownloadDocument.aspx?Document=787): "The IC-7300 has Auto Notch and Manual Notch functions. Auto Notch: Used in the S
It is really hard to beat the value of the IC-7300. It is not perfect, but considering the features, performance, audio quality, and ergonomics at its price point, it is tough to beat. Not only is th
Rick, From the rumour mill, the upcoming Icom IC-7610 direct sampling radio will have much better bandpass filtering than the IC-7300. Until it is generally available though, I would not believe any
I would add to fix the noise blanker. The noise blanker becomes ineffective with a strong signal on the band. For example, occasional power line noise at my QTH is effectively removed by the noise bl
Wasn't there also a jump in noise from the Tritons to the Omni ABCDs? Only want to add one comment Steve. I'm almost certain you already know this, but I think there was a significant jump in noise f
I agree that the comparison needs to be made using all the capabilities of each rig. Each rig should be set up to present the clearest presentation of the desired signal regardless of bandwidth, gain
I think bringing back the Corsair would be even more expensive. The enclosures and all those controls and knobs cost serious money. Three enclosures: transceiver, external VFO, and speaker/power supp
A K2? It is not even in the same league as the Corsair II. First of all ergonomics, Elecraft ergonomics are terrible. Tiny controls too close together. Multiple simultaneous button pushes to activate
K3(S) mode selection?????? The K3(S) uses a rocking pushbutton to toggle up or down through its basic modes. One also holds the down side of the mode button (ALT function) to select alternate modes.
DSP and SDR terminology seems to be used interchangeably a lot. I think the lines dividing this classification tend to be rather blurry. I'm not sure we can define a truly "SDR" radio. There are two
The IC-7610 has just been announced: http://www.icomuk.co.uk/News_Article/3508/19067/ I know lots of hams like to brag on their new radio but the new does wear off. Many of the users are not satisfie
This is Icom's first try with a direct sampling radio and from everything I have read, they seem to have done a lot of things right and have produced a good product. Yes, it does have some issues and
That may work well for receiving, but for transmitting the ground losses at such a low height would be substantial. QRP with 100 watts. :-) 73, Darrell VE7IU NVIS brought back 80m to usefulness for F

How do you know this? Did you make comparisons with dipoles at greater heights? Low power enthusiasts (QRP'ers and QRPp'ers) make lots of contacts with very little power, so just because you made con
Rick, I agree with most of your suggestions. My comments: 1) SIZE - The size of the box and number of controls are directly related to the cost of the radio. Controls are expensive. So be prepared fo
I've been thinking about this idea of a bigger form factor for the Eagle, the ensuing discussion, and thought I would post my wish list. Perhaps if others join in with their wish lists, John Henry an
It took a very long time for Rob Sherwood's judgements to take hold and for real change to happen. The fact that some manufacturers are taking steps to improve the cleanliness of transmitters is enco
There are so many things to consider when one chooses a radio. I went through this recently. In my case I wanted the brand, form factor, and ergonomics of the Kenwood TS-590S, the continued developme
