WorldwideDX Amateur Radio Forums

I could be wrong but I seem to recall there was a MOD that you could do to some Yaesu radios that would open up a wide receive range well beyond what you could transmit on, so I suspect that is what might be expected here.

However from what I read, I thought that this software just opens up the band that the radio is capable of so it can transmit out of the HAM band to the limits allowed by that model of Radio. So for example if you have a 420-520 that's all you'd get. I also vaguely recall that you can open up the radio and tune it by shifting the band if you have a scope, but others here would know more about that than I would.

In Canada the KG-UVD1 managed to get DOC Type Approval, so it seems that many of the ones that are being sold there are already open for transmit on the bands they are rated for so this software may not be required. I'm not sure about the demographics behind the HAM versions, are they mainly sold in the USA, or are they also being sold elsewhere?

hji all am noew to radio and having trouble with what numbers to put in and where..
can any one help ?
thanks

Hi Remote.

Yes, you are correct.
One should be very carefull on transmitting outside the ham bands.
Where i live the 155.475 is mostly used by hunters, timber lorries, forest workers etc.

Radios usually consist of two main blocks, a microprocessor and an RF deck. You can use software to change the frequency range that the processor will display. It is usual for the VCO in the RF deck to be aligned to work over a set frequency range, and possiblly a bit outside the advertised range. So even though the micro is displaying a frequency the VCO ,and therefore the radio , will not work unless it is aligned for that frequency. VCO alignment was done in the factory and may involve changing a capacitor or software to change the VCO parameters, or most likely both. I have not been able to find a VCO alignment procedure . Dont expect the radio to work outside the advertised bands unless you can realign the VCO.

Hey guys, I'm having issues getting a driver to work with the radio and cable. Could someone be so kind as to take a looky and see what driver windows is using please? I'm on Vista. Thanks.

Mine is the Prolific version 3.2.0.0 dated 7/31/2007

And that one did the trick! Thanks mate, now I can go back to the fun of deciphering the Wouxun manual

I must say that for the money these little jiggers are amazing. One hell of a lot of radio for very little investment. It makes you wonder about the cost of the SRP-9100s that these will be replacing in a lot of cases around here. I bet they don't cost all that much more to make.

I opened up the band limits on my Wouxun with no problems. However, I was wondering is there a way to program the channels/frequencies so the unit will not transmit on a channel?

For example I have the local WX freq. 162.550 mHz programmed into the radio and I don't want to say sit on the HT and irreverently transmit on 162.550 and have the FBI come knocking on my door a few days later.
