What is the best HF transceiver these days?
Hello,
I've been out of the hobby for years now, but want to purchase an HF rig, possibly with the 6m and 2m and even 70cm options. My main concern is that the radio have the best and most flexible receiver possible. I'd like to do some DSP work and if the receiver is a software receiver and is programmable, that would be very desirable. I was looking at the TenTec site and they advertise a transceiver with 0.35 uV sensitivity at 10db S+N/N in a 3KHz SSB mode. On the other hand, the Kenwood 480 guys are claiming a 0.10 uV sensitivity, but didn't say what mode. It looks to me like TenTec is the most technologically advanced, but then why the lower sensitivity? I wonder if Kenwood is not completely truthful. Well anyway, what's going on? Are these the right brands to be looking at anyway? Thank you, StevenS |

In either case, the sensitivity is excellent and you as the operator probably won't notice the difference. Your antenna setup will make the major difference. Instead, decide what features you want and how important each feature is to you. Then see how the various radios stack up. For example both my husband's Icom 741 and my Kenwood TS-2000 have built in keyers on which you can set the speed. However on his there is no readout as to what the speed is. You have to just set it by ear to the approximate speed that you want but within its range it is infinitely variable (i.e. not limited to whole number increments). On mine, I get a readout of the setting and can set it at a specific speed. but it is limited to whole number increments. So what do you prefer? His radio allows the add-on filters internally as well as having DSP. Mine does not. Again what is important to you? Dee D. Flint, N8UZE |

I would not concern thyself with BPL too much.....
they have got enough problems of their own. -- KG4LBD "QrZdoTKoM" QrZdoTKoM@QrZdoTKoM wrote in message ...

There are a couple of those now being manufactured that might be better platforms for doing DSP work. |

Firstly, Ham Radio is not a hobby, it's a technical pursuit.
The best transceiver for any self-respecting _REAL_ Radio Ham is the one that he conceives and makes for himself. CBers, OTOH, have a hobby and buy their rigs off the shelf, even sending them back to the emporium if needing repair. You'd be surprised at how many CBers-Masquerading-As-Radio-Hams there are to be found today!

Looking at sensitivity without examining the other receiver characteristics
won't tell you much. You should take into account all of these: Sensitivity Dynamic range Selectivity -- Filter Characteristics such as Shape factor (skirt selectivity) and ripple Intermodulation Distortion Phase Noise - Noise floor Minimum Discernable Signal DSP performance More See Selecting a rig at URL: http://www.arrl.org/tis/info/pdf/29379.pdf Then read the reviews The ARRL transceiver reviews is a good place to compare these specs and what they mean. http://www.arrl.org/members-only/prodrev/ A rig can have super sensitivity specs with lousy dynamic range -- it is difficult to get both -- lots of tradeoffs in receiver design. Dynamic range is a very important receiver spec as is selectivity as well as sensitivity. Look for high receiver intercept points, excellent dynamic range, sharp selectivity and a low phase-noise synthesizer Be careful when comparing a $1000 radio to a $3300 radio -- there are usually good reasons for the higher price.
