I like the menus if they are done well. Hp started to use soft buttons in the 80s and hasn't gone back. |

I have no doubt that the menus are easy to use--that's not the issue. My concern is that they're tedious to use. Having to go through a menu to get to a function just can't compare to having a dedicated control for that function. The menues are adaptive....that is, the functions you use most often are nearer the top. There isn't any tedious hunting. And you can set preferences for nearly every frequency you use. My recommendation is to use one for a while. Not just around the block. For a weekend. After a while, the menu trees become not only second nature, but transparent. And most functions you prefer to use are near the top. The menu trees are really not an issue on this radio. I agree with you here. It does become second nature. There's nothing cognitively challenging or demanding about the menu structure *at all*. However, from the point of view of ergonomics it literally boils down to a matter of efficiency and economy of hand movements, as is so often the case in this area. But this is still a minor nit to pick with what is unquestionably an outstanding receiver. Steve |

Yes and since HP, then Agilent went the way of the menu they lost a lot of sales to Anritsu that made comparable equipment with a knob or button for every function. Personally I didn't care but most other people did care and so it goes. -- Telamon Ventura, California Oh please. If you don't see Agilent gear in the lab, it's Rhodes and Schwartz. |

Analog versus DSP
This thread seems to have migrated from a DSP vs. analog discussion to
one of ergonomics of buttons/knobs vs. menus. What I'd really like to know is if there's any significant reason to prefer a DSP-based receiver (e.g. the 756Pro-III) over an analog receiver (e.g. AOR 7030+) on the basic of receiving performance. Here's where I perceive DSP receivers to have the advantage: * Sharper, narrower filters without artifacts (e.g. ringing) * Easy updates via software download (TenTec supports this, does Icom? (I doubt it)) and for analog: * Higher dynamic range than most DSP receivers * Lower cost (typically) * Better audio I had a chance to sit down and use a 756Pro-III for a few hours this weekend, and I must say the spectrum scope is an addictive feature! |

Digital filters ring unless they are sloppy. IIR filters ring. FIR filters don't ring IF the tap coefficients are all positive, but then the filter is sloppy. With DSP you have more control over the bandwidth, but no freedom from ringing. I don't think the 7030 is all that cheap once you buy the filter daughter board and some crystal filters. The filters don't just materialize in the radio. You need to solder them or pay someone to do it. |
