Programming a Baofeng UV-5R for PMR446  Kijk naar?

Technical Reference/Programming Radio
Nice feature of the Baofeng UV5R family is that they support 6.25kHz tuning steps. That fact makes it possible to dial in the radio to use the exact PMR446 channel frequencies rather than a nearest fit which is the case in many other transceivers.

ICOM IC-756 PRO II Review  Kijk naar?

Radio Equipment/HF Transceivers/ICOM IC-756
I give the Now Long Discontinued ICOM IC-756 PRO II (2) a luke warm Thumbs Up for Shortwave Listening use due to it is fair to poor receive audio quality. The matching power supply and speaker fare even less . But as a hybrid DSP set for the Amateur who will be transmitting as well as receiving, the PRO II is a good deal in my view.

Yaesu FT-450D Review  Kijk naar?

Radio Equipment/HF Transceivers/Yaesu FT-450
Nice affordable Transceiver for Amateur use, but understand the caveats. Receiver performance is actually good, however the fair to poor ergonomics, hissy receive audio and fan noise just in receive mode make a sour outcome for SWL use
