Hand held radios, I wouldn’t know what to do without them. For a while I had the feeling that not much spectacular developments were to expect. That proved not to be true. There are some trends in our little radio world standing out lately:
- more output power
- more bands
- independent VFO’s
- cross-band capability
- Digital Voice (DMR, dPMR)
One of the brands trying to hitch a ride on some of these trends is the not-so-well-known brand Topsung. Their latest offering is a hand held covering three bands, delivering up to 10 Watts output and a 2500mAh battery to power it all. DTMF, ANI, CTCSS, DCS and a scrambler are standard features.
Personally I don’t find anything above 5 Watts output very useful, as range depends more on antenna quality and terrain than raw power. Pumping out 10 Watts close to your face might not be smart either.
Also, the third band (350 – 400 MHz) is pointless and illegal almost anywhere in the world. I’m sure my friends in the USA would prefer 1.25 meters, and we Europeans would kill for 4 meters or 23cm.
