Box 10 pcs PNI HAM27 Multi Band Portable Radio Scanner for Amateur Radio, All Strip Scanner

Design and general purpose

PNI HAM27 is a portable radio scanner — intended for receiving radio signals — designed to cover a wide spectrum of frequencies, from very low frequencies to over 1 GHz. The device is compact and easy to carry, with small dimensions, which makes it suitable for mobile or portable use. The antenna can be connected via a standard connector, and the difference from a complete radio station is that the PNI HAM27 only offers reception (RX), so it does not transmit.

Reception and frequency coverage

A strong point of the PNI HAM27 scanner is its wide frequency coverage: it can receive between approximately 0.153 MHz and 1160 MHz, offering an extremely wide spectrum — from low bands to UHF and even beyond. The scanner also supports up to 999 stored channels, which provides flexibility for monitoring many frequencies simultaneously. The reception quality is supported by adequate technical sensitivities: for example, for FM — at 21 dBm, for WFM — at –108 dBm and for AM at –100 dBm, offering the possibility of capturing signals with very varied power and modulation.

Functionality and operating modes

The scanner interface is designed to provide flexibility: the user can switch between “channel” and “frequency” (VFO) mode, allowing either the selection of preset channels or the manual setting of the desired frequency. There is the option of dual reception (dual-watch), although with some limitations depending on the selected band. The side buttons allow quick access to useful functions: for example, one of them activates the monitoring function or — by a long press — activates the FM radio function; the other button allows activation of the LED flashlight. Thus, the PNi HAM27 is not just a radio scanner — it also has auxiliary functions that can be useful in the field.

With the radio in frequency mode, press the # key to enter the desired frequency.

Power supply and autonomy

The device is powered by a 7.4V Li-Ion battery with a capacity of 2500 mAh — which provides a reasonable autonomy for portable use. Charging can be done either via a dedicated charging station (docking station) or via the USB-C port, providing flexibility depending on the context. It is important to note that the battery is not delivered already charged — so the first thing after purchase is to fully charge it — and that charging should be done in a dry and ventilated environment, avoiding overcharging.

Limitations and safety aspects

Although the PNI HAM27 offers a wide range of functions and coverage, the device also has important restrictions and limitations. First of all, it is not waterproof — thus, its use in rainy conditions or in humid environments is discouraged. The scanner can also generate interference and, therefore, its use may be legally restricted in certain regions — it is the user's responsibility to comply with local legislation regarding the reception of radio signals. In addition, the use of non-original chargers or batteries can lead to malfunctions or safety risks, so it is recommended to use only approved accessories.
