Just a thought - the USB interface concept is "nice". But it is

horridly short range. There is something to be said for the ability to have the radio on a somewhat longer tether than USB allows, particularly the newer USB2. A good tuner is not going to fit inside a radio as small as the 7000. Low loss requires large components most of the time. (I start shivering well above temperatures suited to even the highest temperature super- conductors we have.) The user interface aspects of the dual transceive may prove the downfall of such a design attempt. But it "might" be nice. (Do everything generally leaves out the "well" word. There is a time, place, and market for it. Just be aware of the tradeoff.) For FM running down to 9.6 volts is easy. For SSB you raise your distortion considerably. A power supply to boost the 9.6 back to 13.8 is costly and consumes volume. It's a tradeoff. (A rig that can run down to 9.6 volts and has many users who routinely do that could earn the same revulsion from me I felt for the Swan 6 meter transceiver that splattered across 6 meters instead of behaving nicely in most instances.) LED backlight is indeed a really good idea whose time has come, I suspect. DRM in the DSP may be a good idea. I have mixed opinions. For a little thing like the 7000 I think it is a very good idea. For a big thing like the ProIII or 7800 I believe DRM and other decoders belong in attached computers operating off an Ethernet supplied feed from the IF strip's I/Q "if" information after basic bandpass filtering and such. That way a computer can provide much of the DSP function. This allows an instant modulation mode update as the technology base grows. In line with that last I want the digital IF outputs "tapped" just before the demodulation to baseband for SSB or whatnot. I also want the digital baseband "audio". I want 'em on a nice TCP link by command over that same TCP link. That is fitting accompaniment to Ethernet based remote control. {^_^} Hey, W6MKU can dream, can't she? ----- Original Message -----
From: "MKM" <mab2000@...> correct, too late now but the mk2. Note to Icom: - I want digital audio IN/OUT. - I want a complete antenna system for the car a la atas-120, or a new AH-5 tuner that follows frequency change and tune the antenna system without transmitting each time (from memory of previously tuned values). - Software upgradable through ethernet port which is also used for remote operation. - Ability to receive one HF band in SSB/CW and 2m FM AT THE SAME TIME. This is possible if the fm side of 2m/440 is just a classic non-dsp design as there is only one IF-DSP chain. - Please make sure that if we connect ICOM's 2.4 GHz converter, the display corrects itself for the proper band operation (not displaying 2m frequency while in 2.4ghz mode). - I repeat my desire for the ethernet port or a USB 2 port. Lets dump the old control interface for the new USB 2. - Ability to run down to 9.6V with reduced RX current and power limited to about 5 watts with display auto-off - Make sure you use LED backlit for the display. - Why not put the capability to decode DRM in the DSP and be the first Amateur equipment to do so. I do not think there will be enough room for video out for external display. -best On Feb 28, 2005, at 4:39 AM, Brian Mury wrote: On Mon, 2005-28-02 at 01:13 -0800, Adam Farson wrote: Yahoo!
