WiMo PicoAPRS-Lite APRS Transceiver Module
PicoAPRS-Lite APRS Transceiver Module - the little brother of the popular PicoAPRS. This is a tiny APRS tracker weighing just 7.2 grams*! Even though the PicoAPRS-Lite was developed with balloon flights with APRS payload (Pico balloons and stratosphere balloons) in mind, it can naturally also be used for many more APRS purposes. Thanks to its small measurements of just 27.8 x 66.9 x 6.3mm this tiny tracker can, for example, be installed nearly invisibly in cars. This allows for APRS usage without annoying wiring in the car or too short antenna cables. You can even carry the tracker around in your pocket! An SMA antenna jack is offered separately since its weight of about 2 grams is an unnecessary extra load for the light Pico balloons. This is also the reason why the tracker is being delivered without a case. Special functions of the PicoAPRS-Lite: - Automatic or manual frequency tuning on request. E.g. automatic for worldwide balloon flights. - In areas without APRS coverage and with automatic frequency tuning the ISS APRS frequency is used to be heard even in these situations. - Temperature and air pressure sensor. The values will be sent as an APRS comment in every position. - As an energy source a small solar cell with buffer capacitor can be used, as well as single-use or rechargeable batteries. - Voltage range ca. 3.2 - 5V. - When using a solar cell the PicoARPS-Lite will stay in battery-saving mode use only about 0.1mA until the buffer capacitor has stored enough charge, then sends a beacon and will go back into battery-saving mode to recharge for another beacon if needed. - Even with just one solar cell which supplies the buffer capacitor with just a tiny amount of current it can operate forever in sunshine! Ideal for a world trip with a balloon. - Even when using batteries the energy-saving mode will be used between beacon transmissions to extend the battery's lifetime. - Micro USB port for settings configuration with a terminal software. - Integrated GPS module with balloon mode up to 80km height, ideal for stratosphere balloons. - Transmission power configurable between 0.5 and 1W. - 7-pole lowpass filter to eliminate unwanted spurious emission. Status LED - Firmware updates via USB possible. Future wishes of users and product improvements can be uploaded later. Beware that this device has no voltage regulation! When operating with a solar panel and buffer capacitor the service voltage will usually drop to zero at night. With sunrise the device will be operational soon again. It's important that the tracker can be used with as little power as possible. A voltage regulator would cause a voltage drop which would be inconvenient during sunrise/sundown. To limit the maximum operating voltage a beacon will automatically be transmitted when reaching about 5V in balloon solar mode to use up stored energy. Doing so the maximum operating voltage won't be exceeded even when the idle solar cell provides too much voltage. *1) Weight without antenna jack, case or any energy source. Suggest accessories to be obtained from other sources: - SMA jack for circuit board mounting, upright, with long thread, for single hole fixing. If the device should be in a case and used with a regular antenna. - Lithium polymer battery 3.6V/800mA, as well as compatible connector cable for an external energy source. Beware, the PicoAPRS-Lite has no voltage regulator for batteries! Never charge batteries via USB! - Small USB charger for 4 LiPo batteries max.

WiMo Transceiver Lifting Handles
WiMo Transceiver Lifting Handles let you lift your expensive transceiver and set it down vertically, without risking damage to the rear panel connectors. Available for a limited number of popular transceivers, these black powder-coated strong metal handles are available in two styles. Angled handles flair out, away from the controls for a better grip. Straight handles allow equipment to be set side-by-side. All versions of the WiMo lifting handles come with mounting screws. The FT-710 version of the lifting handles are angled on the front and have a cutout for the SD Card slot. The Universal version of the lifting handles are straight. Set your transceiver face up on the floor or desktop without worry. Order WiMo Transceiver Lifting Handles from DX Engineering

WiMo Aluminum Telescoping Masts
WiMo Aluminum Telescoping Masts are convenient for many tasks. Made of a strong yet lightweight weather-resistant alloy, these metric-sized masts are primarily intended for temporary and portable use. They may also be used for long-term installations with the WiMo WMO-23050 Metal Guy Ring Kit. The versatile masts have a range of uses, including vertical antenna construction, installation of weather stations, and mounting of a security camera. They're made of slotted aluminum tubing that can be extended to the desired length. Mast models are available with extended lengths of 5 to 16 meters (16.4 to 52.5 ft.). Each section can be locked solidly in place with the attached clamps. Load capacity of the masts is determined by the clamping length and height; depending on the diameter, weights up to 4 kg (8.818 lbs.) or more are possible. The maximum extension length of each section is limited by a marking ring at approximately 20cm (7.874 in.) above the bottom of the tube. The sizes of the telescoping aluminum tubing are in 5mm (0.197 in.) increments, with a nominal wall thickness of 2mm (0.079 in.).
