This is a short review because the INTEK is basically a Baofeng UV-5R on steroids. A new PA stage effectively doubles the power output of the radio: maximal 8 Watts on VHF and maximal 7 Watts on UHF. Contrary to many fantasy brands found on AliExpress.com INTEK doesn’t make up crazy numbers. So far, so good.
Changes in the INTEK KT-980HP
– TX Power Menu offers three output settings: Hi, Mid and Low.
– The INTEK is slightly heavier: 217 grams versus 210 grams.
– More efficient heat dissipation (and it works)
– Special firmware (HP 3.01)
VHF: High 6.4 Watts, Medium 4 Watts, Low 1.1 Watts
UHF: High 5.3 Watts, Medium 3.9 Watts, Low 1.1 Watts
Not quite at the promised levels, but the difference is substantial.
VHF: 2nd harmonic not detectable (!), 3rd and 4th harmonics -57 dBm
UHF: 2nd harmonic -42 dBm, 3rd harmonic -53 dBm.
Acceptable on VHF, slightly disappointing on UHF.
There’s one thing bothering me: what’s the point? Doubling the output power (+3dB) doesn’t necessarily translates into a better range. At high elevations and completely free line of sight (between 2 mountain tops, for example) you might expect an improvement of around 30-40%, but at ground level you likely won’t notice an improvement at all.
All reservations aside: INTEK did a reasonably good job. The radio didn’t quite meet the factory specs, but at least we see some new developments on the market. One thing: the stock antenna is poor, runs dangerously hot and should be replaced by INTEK as soon as possible.
