Re: FRV-7000 RE: New Member from Australia
- Hi Andre,
what I found to be the key to making the FRV 7700 work at all is totally in tuning it up.
The best way I can explain it is to do the following.
Firstly find a know transmission frequency on VHF, in my case I looked on the internet and found 126.800mHZ for the local airport.
Select the appropriate band on the FRV, eg 118-130 in this case, then set the FRV to VHF on the funtion switch.
Set the FRG to 26.798mHZ (mine is out by -002 at this point)
Remembering that the FRV adds 100mHZ on 118-130
Set the FRG to AM-W. Turn the volume up a bit so you can hear noise.
On the FRV rotate the IF preselector until the noise on the FRG increases the most, then rotate the RF preselector until the noise on the FRG is the loudest. This will make sense when you do it.
Even if there is no vocal being transmitted at the time for some reason this process of tuning the noise dials you right into the specific frequency. Then select AM or AM-N or FM depending on what is required and you will have it loud and clear as soon as there is a vocal transmission.
I have tried the same process on 144mhz, tune the IF and RF on the FRV until the FRG (AM-W) is loudest, switch to FM and you will receive good quality sound from repeaters etc.
I also have a Uniden Scanner, the FRG and FRV absolutly kills the Uniden in signal strength and sound quality tuned in this method and both units tried on the same antenna.
You need to retune the RF and IF Preselector for every different frequency, but it is worthwhile!!!

- Thanks Web,
the set was in regular use up until about 2 weeks ago and was upgraded to something more modern. It has one meter lamp out and thats about it, I had a look on FoxTango and got some information to get another lamp. Will let you know when live on 10M.
