From www.wiierrorcodes.com Wii Error Code 50300 - 50399

This error is caused by incorrect internet connection settings, such as network name (SSID), WEP/WPA keys, or any manual settings.
To solve this error :
Ensure you have correctly entered basic information such as network name (SSID) and WEP/WPA keys.
Try changing the channel of your wireless router to either channel 1 or channel 11 which can increase download speeds. Be sure to test both channels to see which works better or faster.

I have a manual for this radio which I could upload.

You can try to reset it by unplugging it let it sit for a minut or two count to ten and least then plug it back in this lets the micro reset itself

HI mullinsallya unplug it from the mains, plug the aerial into the hole which says RF in, then assuming its a Scart type, plug the Scart lead into the TV Scart socket on the freeview box, then the other end into the TV FULL scart if you have two, plug it in and switch it on, may need re-tuning due to the channel 5 fiasco. Menu button settings, or setup, or installation, if you see a "First Time Setup" use that, as it will wipe all previous installed channels and give you the latest channel config. , then usually its a case of save and exit or sometimes just exit by pressing the menu button again.

Perhaps.
[Haven't been involved with this for a Number of years, so bear with me]

You need the correct number of channels first of all.
Each channel operates something on the radio guided craft.
1.You need 1 channel to vary the throttle speed of the engine. (Makes the Main Prop, and the Tail Rotor spin faster or slower)
2.You need 1 channel to tilt the Prop.
[To go forward]
3.You need 1 channel to move the tail rotor vane. [To turn]

If the radio controlled RC car had the options, 1.Of how fast it would go, (1 channel),
2.The wheels turned, (1 Channel),
3.Plus had Lift, (1 Channel), you're good to go so far.
[Lift = RC cars that had option to raise the front end up, like a real car with hydraulics]

Next comes the question, of how far the radio controlled car's transmitter will transmit.
You not only have to take into consideration of how Far away from you, but also how far UP.

Fly out of range, and your 'bird' will drop to the ground like a Rock! (No wings to glide down)

You can't "select" channel 70, nor can you talk on channel 70. Channel 70 is reserved for the exchange of digital data between radios.

And it is not possible to address an "emergency" (do you mean distress? or urgency?) message to an individual recipient.

Your radio is not allowing you to do any of these things because it has been (correctly) programmed to discourage you from doing things that would be illegal.

If you set up a routine call with your friend (or anyone else), you should find that once the two radios have completed their (almost instantaneous) exchange on Channel 70, they will both switch to whichever working channel you had selected, and he will get a beeping sound to tell him that there is an incoming call.

Sounds to me like both radios are doing exactly what they are supposed to.

to get digital, you need to do the autoprogram or channel scan.. then it will find them and add them to your channel. point your antenna toward your towers and re-scan the channels. if you want digital cable, you need a cablecard (where applicable) or cablebox to decode..

THERE IS A TAB ON THE VCR TAPES IT CAN BE BROKEN OUT TO KEEP PEOPLE FROM TAPING OVER YOUR PERSONAL TAPES.LOOK AND SEE IF THIS IS NOT BROKEN OUT. IF IT IS PUT SOME TAPE OVER IT AND IT WILL RECORD ON THAT TAPE AGAIN.
