Yes, they are. Generally speaking, authentication is legal, obfuscating is not legal. So you could do a cryptographically signed hash that would be legal in the United States to transmit over Amateur Radio. It's worth mentioning that there is some debate as to how legal a cryptographically signed hash would be. I believe it would be legal, so long as it was ...

There's a few parts: §97.109 Station control. (d) When a station is being automatically controlled, the control operator need not be at the control point. Only stations specifically designated elsewhere in this part may be automatically controlled. Automatic control must cease upon notification by a District Director that the station is transmitting ...

How you do this will be dictated by the software you select. However, most software I have seen uses some of the control lines on an RS-232 serial port. Calling it a "standard" might be a stretch, but there seems to be a convention: More at the source, F8EHO.net. It's also possible to use some of the other control lines to drive an opto-isolator or relay ...

A really easy way to do this is to take an old USB mouse (or even a new cheap one) and solder the key across the left mouse button. You can then use key directly as mouse button input on most computers and Android phones (with an OTG cable) and use with Morse software or websites expecting mouse input e.g. :- http://morsecode.me http://www.web-adventures....

I'm not aware of an application that has full control of every feature. However, there are a variety of applications available that work for basic functions. FLRIG will give you many of the most common features. I use the related program, FLDigi, for operating digital modes with my FT-450D. Its rig control is sufficient that I don't generally have to turn ...

The "data" cable you picture provides only audio in and out. Some other device, like a TNC or a computer, must provide the modulation and demodulation to provide any data capability. Additionally, the cable picture does not expose the PTT connection on the data port, so with that cable alone there's no way for the computer to key the transmitter. However, ...

Yaesu makes software like what you're looking for: Go the yaesu.com and find the FT-450D page, click on the Files tab, and look for: PCC-450 Software V1.13 and Reference Manual (07/18/14) The PCC-450 software runs on Windows and connects to the radio over a serial port. You can drive nearly every feature of the radio. I find it easier to use this software ...

I believe that according to §97.3, logging in to a remote base through the Internet is considered remote control. Therefore, the amateur logging in is the control operator, and the normal identification rules apply. The base does not need to identify separately. That said, if there's a repeater linked in to the system, such that transmissions are ...

OK: Windows host for SoftRock Ensemble RX II, remote control of digital modes - why not an COTS (Cheap Off the Shelf) solution, such as TightVNC or other VNC solutions? Since you are talking about station control, not voice, the lack of voice is not an issue, is it? It's GPL open source (free as in beer), even cross-platform, and supports Android and ...

A remote control is just a radio transmitter (maybe even a receiver if you expect to get data back from whatever you're controlling). To get started, you'll need to learn how to build a transmitter/transceiver that operates at the appropriate frequency. That's probably the easy part. schematics for VHF/UHF transmitters shouldn't be too hard to find. The ...

Well, I can't answer as to “standard” as I'm just learning myself, but I can think of a couple of ways to do this without getting into completely custom interface hardware and drivers, or needing an interface with directly readable signal lines like a serial port or parallel port which is less common these days: Connect the key to a code practice oscillator ...

The inactivity timeout is controlled by the auto-power-off menu setting where you can designate the number of minutes, such as 30 minutes, for the radio to be switched off. But, this is tantamount to turning the radio off just as if you had pushed (and, held) the power button on the front panel. It is not some "sleep mode" where functions are still active, ...

When you suspect timing problems with FT8 decodes, simply manually adjust your computer clock to see if the situation improves. This is also the standard recommendation when you suspect the transmitting station's clock is off. It is quite possible that you are having timing issues since the Internet is nondeterministic. It is not uncommon that in a ...

The YT-100 will not automatically initiate a tuning cycle when there is high SWR present. There is, however, a simple solution to your problem. The YT-100 has a 1/8 inch jack that facilitates a remote tune button (see page 16 of the manual). You could run a shielded, decoupled cable to a push button at a convenient location; you could use an RF keychain ...

According to clause 17(ff) in Ofcom publication, UK AMATEUR RADIO LICENCE, Section2: Terms,conditions and limitations, "Remote Control Operation" applies, "...where the Licensee has the ability to control the Radio Equipment from a different location to that where the Radio Equipment is located;" Since your control means and your radio will both be located ...

Yes, remote control is not only possible, but it is easy. The FT-450D is not like a naked SDR. It may be one internally, but it does not need a program like SDR# to operate it. That being said, there is a great program available that allows the front panel of the radio to appear on your screen, and you can use the keyboard and mouse to control it via ...

Please see: §97.309 RTTY and data emission codes. (a) Where authorized by §§97.305(c) and 97.307(f) of the part, an amateur station may transmit a RTTY or data emission using the following specified digital codes: (1) The 5-unit, start-stop, International Telegraph Alphabet No. 2, code defined in ITU-T Recommendation F.1, Division C (commonly known as “...

That software appears to mimic all the controls of the rig. As it is free, it's worth trying it out. There is a useful list of alternatives here: http://www.dxzone.com/catalog/Software/Radio_Control/

I am the author of the free-ware DXLab Suite, one component of which -- Commander -- provides transceiver control that supports the IC-7100. However, Commander is not designed for remote control. The two applications most frequently used applications for that purpose are TRX-Manager and Ham Radio Deluxe . Neither is free, but both offer a free trial. User ...

Many CW keyers (such as the WinKeyer) will convert what you key back to text. I used flwkey to see what I was (attempting) to send as code practice.

If you're feeling technically adventurous, then I have written something that might fit your needs. I wouldn't consider suggesting this if it weren't that as far as I know web-controllable SDR software is a very small field (there is only WebSDR, my thing, and another early-stages program I've forgotten the name of). My ShinySDR is a SDR application based ...

This might be better as a comment than an answer (Mods feels free...) but... Given your callsign is from the USA, your terms are different from mine in the UK, but please check the terms of your licence... I could be wrong but I suggest that what you are proposing using ham bands for is outside the privileges contained therein. Furthermore, remote control ...

The not yet commercialised FlexRadio FLEX-6000 series is said to be going to offer OS-independent remote operation.

Ten-Tec Omni VII HF+6m Transceiver supports MS Windows. The remote GUI program can be downloaded here. I do not know about Mac OSX or GNU/Linux.

I recommend you don't reinvent the wheel. There are two amateur radio bands in the US the FCC sets aside for line-of-sight remote control for planes and surface craft (boats, cars, etc). The RC community has determined standard frequencies and uses the same modulation and protocols as on other license free bands, so as long as you follow their guidelines ...

I would strongly consider a Zigbee or 802.11 based approach. Both have cheap hardware available, are relatively easy to integrate with electronics (via a microcontroller such as an arduino), and operate on frequencies which you have extra privileges with your ham license. Depending on what you are wanting to control, it would be fairly easy to control via ...
