• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Interested in getting licensed for your own HF frequencies? Step right in!

Complexity and points of failure. HF requires ZERO infrastructure whatsoever, not even a satellite. That means that no matter how far apart yapper 1 and yapper 2 are, you only have two devices to troubleshoot. There is a nice simplicity to that.
And the atmosphere. I think that’s where reliability is lost.

Financial traders like it because it's speed of light(-ish) directly between points.
Satellite has a longer delay.
IP networks have a longer delay and varying paths.

When stocks are getting traded quickly, those few milliseconds can add up to a lot of money. A direct point to point connection can be worth a lot.

Fiber has a VF around 66%, similar to RG-58. I read about those high speed trading firms putting in microwave links from the Chicago bored of trade to Wall street to get milliseconds shaved off an internet based VPN. Who da thunk?

Plus all the routing that happens on IP networks. You never know what path your packet will take once it hits the interweb tubes.

Surprisingly, there was even a movie about it: The Hummingbird Project. It didn't do well.

Simplicity? Propagation, solar conditions, etc. might not agree.

I mean, that's a very very fair point, and I don't discount it.

You and I both know I was speaking in fear of Parkinson's Third Law though, where it intersects technology. An adequate tech spec will know how to add complexity to a system. A GOOD tech spec will know how to remove it. I just hope and pray I can be good enough to not have a complex system failure during my career :oops:.

That said, yeah, there's a lot of math and dice rolling that can go into getting HF to work too, so you got me there :)
