Δημιουργήθηκε νέο TG σε BrandMeister με αριθμό 31699 και όνομα GREEK-AMERICANS . Το συγκεκριμένο TG έγινε με σκοπό να εξηπηρετησει όποιον επιθυμεί να επικοινωνήσει με Νέα Υόρκη στον τοπικό αναμεταδότη, με hotspot ή αναμεταδότη μέσω BrandMeister.  Η δημιουργία του έγινε από συνάδελφο στις ΗΠΑ.

Usually the case is that we are close to a radio station transmitter(for repeaters) transmitting with some kilowatts, or near an airport and this is causing problems!!! In such case you need to have a filter cutting out these bands. The filter described here is for the VHF Band (2m) and it is really easy to construct. You will need the following: Notch filter block diagram Coax cable (good quality LMR-240,400,600) T connector ,bnc or n-type Signal generator & spectrum analyzer so you can tune your filter to the desired frequency A plastic electrical box to use it as enclosure (if you wish) I personally wanted to create a Notch Filter for a near by Radio Station that transmits on 94.5Mhz. So after some quick calculations: The Wavelength of 94.5Mhz is 3.17m LMR-240 VF = 0.84 So for the 1/4λ coax stub: 1/4*3.17*0.84 =  0.6657m = 66.57cm For the 1/2λ coax section between the 2 stubs: 1/2*3.17*0.84 = 133.14cm = 1.33m Personally i constructed a one st...

The review for this handheld radio will be a quick one! First of all to sum up   DO NOT BUY THIS RADIO   if you are an amateur radio operator Pros: Robust construction Splash proof 10w tx power output Big battery Easy to program Cons: One timeslot Low tx power 4w Bulky Not amateur radio material Bad modulation Produces high BER even when you are 5m from the hotspot(when other radios are perfectly fine) If you want to spend money on something better go a offer the value of this radio to someone who needs them because if you buy this radio is like throughing your money to a dumpster. For some people that think that there might be a solution to the one time slot thing, there is not!!! This radio only trasmit in one time slot TS2. You cannot use it on a repeater because you will produce a mess!!! Finally this radio is not support by the DMR community so you will not find information nowhere. Even TYT says do not buy this radio if you are an amateu...
