The first Chinese HF rig?

Post by VK2AXL »

This may be a wind up. But it may be real. Its interesting though.
It was only a matter of time before our Chinese neighbours started ripping off Japanese HF rigs.

Check the price - $400 ! It looks to have programmable preset channels rather than a VFO.

This is a broadband transmit radio for marine use only. So I know that all amateur radio licensees will have the integrity to resist buying one on ebay from Hong Kong.

I now have a mental image of ACMA staff with their heads in the hands weeping.

Not only that Jack, a 10m FM box (27.5 - 39.5 MHz) http://www.ecvv.com/product/1227996.html

Thats 10m FM rig looks interesting. I'd be interested the hear the price.

Amateurs in other countries will find it useful. Sadly not this one. We cant be trusted :evil:

RX sensitivity of these looks very poor - you won't hear too much with 0.5µV or even 1µV while even
mid range transceivers from Yaesu, Icom, Ten-Tec and others are as standard at less than 0.2µV
Most likely similar are specifications on TX (IP3, IMD) and other specifications ...

Probably it will take some time before they can produce competitive transceiver

Yes you'd need 0.2uV for VHF/UHF gear but I'm not sure it would make much difference on HF due to the higher ambient noise, particularly in an urban environment.

If anything modern rigs have too much sensitivity and too much AGC, which tends to make them sound noisy and flat.

Provided there is a reasonable increase in noise when the antenna is connected then that should be enough.

The trade-off between receiver gain and strong signal handling is probably optimum there.

I would be much more concerned about other factors eg the phase noise of the frequency synthesiser, artefacts on weak signals, filter characteristics, transmitter IMD, quality of tx/rx audio, ease of tuning, smoothness of t/r switching etc if reviewing a budget rig. These things can really affect its pleasantness to operate.

If the Chinese transceivers are anything like their cars and other trash they export to Australia, well, I will leave it to your imagination... :roll:
