Re: [digitalradio] Can not open CAT port (COM1)
1) do a power-off reboot. 2) check for any programs/services that might try to grab a serial port. Frequent ofenders are Palm active sync, or a old UPS managment program. I'm taking the error message at face value. Either COM1 isn't there or some other program has claimed it. Maybe another instance of your control program.

Re: [digitalradio] Re: Mail Clients for Emcomm
To clarify my earlier comment on web mail - what I was suggesting was to set up a local (to each node) webmail machine that would then send SMTP over packet. The interface between the local ham's equipment and the LAN clients would be a web browser. At no time would the http be going over the air. (Except maybe a local WiFi link). Also, it might be easier to set up the web mail server to run text only and to block large attachments right up front. While I'm sure it's still possible to deal with problems the other way, you'd be stuck having to reject and send back a message that the user had already clicked send.

Re: [digitalradio] Mail Clients for Emcomm
Which prospective are you looking at this? The ham or the served agency's? A ham needs to know how to set up his equipment. That's he's job and that's why he's the ecomm guy and not doing something else. As far as the served agency - I'm not sure what the trend is for personal use, but I think Outlook/Exchange is still the predominate corporate email system. So volunteers who are business users will know how to use Outlook. However, I would not count of any of them being able to set up their mail clients. That's what they have IT people for. But now that I think about it ... If the goal here is to make it easy to set up clients for a ham network, maybe we need to be thinking about setting up our own web mail system. Why? It's far easier to create a book mark in each client browser to point to our local mail server then it is to to to install a new email account on every client PC, finding out they don't have admin rights, trying to figure out how this version of software wants it's settings and a whole host of other nasty stuff that only get uglier when done under pressure with people' welfare on the line.

Since I use Gmail mostly these days, and my ISP also has Webmail, I skipped setting up Outlook Express. I wonder if what I did is a sign of things to come? Perhaps many others will eventually just use Gmail or Yahoo Mail type applications for accessing their email. This raises the issue of mail clients for emergency communication systems. I recall that a few years ago, the desire was to make sending emergency traffic as simple as sending an email. Applications incorporated Outlook Express templates within the program. I know it is not really difficult to set up things like Outlook Express but am I the only one that thinks having to set up mail servers represents a step that will confuse the casual operator that suddenly finds themselves having to figure out how to send an emergency message?

Re: [digitalradio] Re: RFI-Free PCs?
I remember it as just the opposite. The idea was to protect broadcast radio and television. Class B was for use in the home where it might interfere with a neighbour. Class A was for commercial use as it was expected to be further away from any homes. If a business interferes with itself, it has the means to correct it. Neighbours don't have that kind of technical knowledge or resources.

The first step is to power your radio from a battery. If doing so cuts the noise, then the noise is traveling up the power cord to the receiver. A noise filter on the AC line will help. Once the radio is battery powered, then go and cut the main power to the house. That will tell you if the problem is in your house or not. These days, most any kind of device that plugs in can be the culprit. It doesn't have to use RF (like cordless phone, etc.)

Re: [digitalradio] The Asus Eee low cost laptop computer
Looks like a nice inexpensive little machine. If your interest is in emergency communications, you probably should think about power. Depending on which battery you pick, you're either looking at 11 or 12W. To run 3 days from battery only power, that's about 72AH of 12V battery just for the computer alone. In contrast, the One Laptop Per Child project is looking at 2W of power, or 12AH for 72 hours of operation. Depending on your application, the difference can be significant.
Re: [digitalradio] The Asus Eee low cost laptop computer
http://laptop.org/ Through the give one, get one program, you can order one for $399 until Dec 31. The laptop was designed for kids in developing countries. It looks like a kid's toy and we'd probably find it a bit underpowered. But from what I can tell, it still has a functional sound card, and the power draw makes it attractive for emergency use. I'm tempted, but I'm short on time (aren't we all?) to find out how this can be put to use. If you've got a generator or even access to a car, I don't think the power draw of a conventional laptop is an issue. But if you've got to survive on battery power, it can be.

Usually about 70Hz. If you push higher, you sometimes loose sharpness as you push the video and crt drive circuits to roll-off frequency limits.

Re: [digitalradio] Mono mic input?
Line inputs are stereo. Microphones are mono, but have a third wire for powering condenser mics - hence the stereo plug and the need for any extension cable to be stereo. If I recall correctly, the tip is power, it's the middle ring that's the audio input, so any attempt at using mono connectors just shorts out the audio input.
