Dear All,

Im looking for some assistance for my walkie talkie set, Icom-V90.

Anybody is using this walkie talkie here?

Besides this, anybody here know any expert walkie talkie dealers in Ipoh?

Thanks and regards,

Pheww took me alost 2 hrs to read all the thread
from starts and need some help and your advice

Me and my friends just got 4 sets of Moto T5720
for this coming long holiday convoy to Samui and
was very disappointed with distance as claims from
the packaging and wondering any sifu's can help

As we will be travelling with 6 cars and hv tested
the range and am worry that when using the last car
might not hear me..

Cheers, :tq:
Basically Moto T5720 Talkabouts are only 0.5W and on the road it is only valid if you can see the car in front of you. If you cannot see, it is most likely they cannot hear you.

If you do this often, I suggest the following solution. Let the lead-car use a 30W in-car unit instead of a handheld to broadcast instructions to all the other 5 cars. Everybody will be able to hear but may not be able to feed-back. Then car 6 relays to car 5 who relays to car 4 and if car 1 can hear and answers "copy", the other cars need not relay. The 30W in-car Wei-Er-Wei set I saw in Shenzhen was the same price as their 5W handheld and they have 128 programmable channels (mine is 400-470MHz) - only RMB300 per unit.
Lean not on your own understanding

I have used the T5720 in convoy of 3 cars only. They work fine, even though slightly out of sight (ie. a few other cars in between). I guess 6 cars is a bit of a stretch. If all 6 cars don't have any other cars in between, then I think it should be OK. But usually, in traffic, some will be caught in traffic light and so there will usually be a few other cars in between.
Like jasonlee said, one solution would be for the middle car to relay the info to the cars at the end of the convoy.
Anyway, the advantage of the T5720 is that it uses big AA batteries instead of the AAA batteries, and also the aerial sticks out quite significantly (compared to the small stub of some other models). That is why I like the T5720. Cheap and good.
