Monitor out to a tv or computer monitor for a big old display.
A full featured scanner

A lot of people have streaming audio from scanners from all over. It would be nice to give the user a way to do that too.. depending on whatever laws and regulations there are places on that.
Yea, having a 2nd display output could work too. HDMI or 15pin VGA/SVGA or ????

Unless you wuld plan on carryinbg around a portable phone/computing device and the little black box, it would be quite bulky.
A nice scanner would include:
P25 Conventional & Trunking
Trunking
Conventional
MOTO All Forms
EDACS All Forms
MOTO VOC
EDACS SCAT
LTR
LTR Mulitnet
LTR Passport
The A.M. Broadcst Band For News & T.I.S. Stations.
Analog and HD audio for the TV band.
No GAPS except for the ECPA 1986 Cell Phone Band
Frequency Range: 400 Kilocycles To 1300 Megacycles
Modes: AM, FM, NFM, WFM, USB, LSB, ISB,
and for those that want to output faxes and other stuff a USB port for connecting to a PC or MAC.
Maybe a MP3 recorder for Audio Recordig compressed audio to a SD card.
Of course it would have multiple step settings for both Search and Scan.
Of course it would have to have two versions:
Handheld
Mobile / Base
A SD Card slot for backup purposes.
Got to have 27 Megacycles in A.M. & S.S.B..
Too much?!?!?!?!
Pick one and stick with it. A BNC is an acceptable connector for below a few GHz. What is the intended upper frequency limit? Giving users a choice is going to add unnecessary costs. The N connector is a better choice because of performance considerations, and the greater variety of cable choices one could use without adapters. The BNC is quicker and easier to disconnect, and some users may look at them as more friendly to work with.
A lower rate is acceptable for communications grade voice quality (300-3500 Hz), and would make for smaller files, and better performance of editing software.
Consider what's actually being used out there. There's several narrow FM bandwidths out there, and you'll need to consider what's happening to refarming of VHF high band. There are other modes that could be of interest too... You're talking of having a VGA monitor on this thing... why not do NTSC video and make it capable of receiving amateur television on 420 MHz and 1200 MHz. Is the upper range at 2450? Make it receive those imported wioreless cameras, too. What the hell!
If the thing must be big, make it fit into a 19" relay rack. Mounting ears optional. If the thing rack mounts, make the antenna input appear on both frong and back panels, like the FT-817 does.
A useless feature that would give meaningless results. You COULD, however, have a calibrated indication of signal strength in both DBM and microvolts. That would make the receiver useful for antenna work.
Let the streamers worry about what the laws are. HDMI so you can include the audio in the same connector.

any protype pictures yet
Post some pictures up. magna doodle, etch a sketch, paper, CAD, Something is better then nothing.
Bring it to the people!
Button placement is a good start also. Small buttons for SCAN and MAN and L/O functions stink. I have small fingers. But, I live in SD it is cold. I wear gloves and like to touch buttons.
LED lights are cool too. What about LED's behind SCAN and MAN buttons.
Show us something please.

I agree about the lights. That always cheesed me off about the 296. There are two buttons that are not lit, And one is the MENU button!!!

Well as for that the hardware development has to be done. But, at least we have a pretty good idea of where we're gonna start at.
I do like some things about illuminated, backlit front panel puttons.
I was suggesting the upper limit be 1.3GHz (1300).
I do have a small 19" rack in my shack taken from a broadcast production studio.
As for the antenna connections.. based on what I've heard so far is that N would work the best. So, we'll go with that, ok?
How are we going to have users input band plans?
I agree about displaying the signal strength in dbM and microvolts too.
In my area, this is the system I listen to the most, which appears to be a Analog voiced Motorola II Smartzone with 10-20 different control channels and it is a system with a bunch of users/areas:

Just be sure you don't get too stuck on the 800 thought process, lots of us are on VHF, analog and digital. Make it compatible with all systems that you can. Light up EVERYTHING, Just my opinion but I think BNC is more common/universal but if N is better at more freqs then you should do that for those that prefer it. Us BNC guys could use adapters and not lose toooooo much I think. Any other views on the connectors?

Oh, no I won't let the project get stuck in 800. That's also why I would make it re-bandable. It certainly would be best to make it compatible with as much as possible. I agree BNC is more common though. I don't know about other people, but I don't go to too many places where I could find a N connector.. but that wouldn't stop me from that.

My wish list
My wishes would include:
1. A full color, touch screen, LCD display. The color and fonts would be user selectable on a per channel basis, so I could have a different look for different services.
2. A remote head for mobile use
3. Removable flash cards for storage.
4. A wireless remote control for across the room use.

It just hit me to suggest this here. I got the idea from somebody in another forum. Include a disc with some video tutorials of programming the scanner to augment the user manual.
New Rig
Why not add USB and LSB/ SNAM /SNFM /anttenuator set per channel and a bullt in discriminator jack ,1MHz to 1300 MHz this would make it similar to the Icon IC-R10. This could be the first receiver that included trunking, APCO25 along with the other modes mentioned.

I agree about adding the disk with the manual, with videos, more documentation, etc.
Would it be a nice thing to have a tone squelch input so you can input a tone into the memory with a frequency, so it will interrupt the search if something is heard on that tone freq??
I'm working on making up a document which encompasses the design features we have talked about here already..
I've decided that this project will be completely Open Source. Having my company be the sole source, I feel would severely limit the scope and intents of the project. However, I will be willing to donate manufacturing time and equipment to the project, as well as access to sources of the components.
Will someone get us a sourceforge, maybe some other group pages going after a master document is created?

Getting a sourceforge page setup is fairly painless. I've done some for a few projects in the past, let me know when you are ready and we can get it set up.
As for the mp3 audio recording, let the user set up the quality they want. Me personally, I prefer 320kbs, and really nothing below 192kbs. Once you get to 128kbs and below your quality starts to degrade fast.

I went ahead and got the SF project submitted, once its approved I'll let you know.

Definantely Dynamic Memory !! Let me know when you get it built. I'll take one !!

Thanks for that Shaft. I'd been trying all day.
I'm working on the document that will describe the project.
I also like the idea of the infrared remote control for armchair, remote control.
Thanks for the PM Mike. Let's get this project off the ground.

I thought we would shoot for 40,000 objects Minimum with 99,999 talkgroups
Still waiting on the group that shaft created to be accepted.
I made a post on strongsignals.net that shows the link to this post.
I've been busy so I haven't had a chance to finish the document I started that is the outline of the project.
Please let us know when the group becomes available.
