Is a WS 1040 easy to program or does it need to be connected to a computer to input freq
There is a learning curve in programming any of the scanner models that use a system different from what you had used before, even moreso if this is your first scanner. While the WS1040, as well as all of the other scanners on the market, can be programmed manually, using software is much quicker, especially when trying to enter text tags for the systems, talkgroups, and channels being entered. Another advantage of software, especially for a new user, is that it's much easier to spot and correct errors and omissions in system entry. You are seeing most, if not all, of the information required at one time on the screen instead of having to step through multiple screens in the scanner's menu, one at a time, to find what needs to be changed or added. Also, with software, you can post your programming file for others to help you find what's wrong, or someone familiar with your scanner or area can provide a programming file to get you started. You can also use a provided file to see how things should be set for proper operation.

Learning how to also manually program your scanner is also a skill that is to your advantage, in case something needs to be added or changed when you are somewhere else, and do not have access to your PC.
