Leading up to the release of the 2024 DX Engineering Amateur Radio Products Catalog in a few months, OnAllBands will be featuring some of the new products you’ll find inside this latest edition. Today we’ll be highlighting a new amplifier perfect for low-power HT operation, a 50A switching power supply, and a couple of excellent new radio reference guides from the Radio Society of Great Britain. Can’t wait for the catalog? All spotlighted gear, along with 30,000-plus other amateur radio and electronics products, are available right now at DXEngineering.com.
RM Italy LA-435 Wideband UHF Amplifier
Take your UHF operation to the next level with this compact linear amplifier. Measuring 4.7″ W x 1.6″ H x 9.8″ D, the unit is ideal for low-power handheld operation. It features 405-480 MHz coverage and required input drive from 1 to 5 watts, which delivers a nominal 60 watts of full output power, 70 watts of PEP maximum. Other perks include automatic “RF Sense” switching between RX and TX, small transmit-receive delay for smoother voice operation, and a rear panel European-style removable DC power connector cable for easy installation with a user-supplied power cable fused for 15A at 13.8 VDC.
RM Italy 50A Switching Power Supply
This dependable, well-built switch mode AC to DC power supply comes with variable output voltage and is suitable for use with all electronic and telecommunication devices. It comes with illuminated voltmeter and ammeter, along with a knob for adjusting output voltage. The power supply (50A continuous/peak load) can be set for a fixed output voltage of 13.5 VDC or adjusted from 9 to 15 VDC via front panel slide switch. Cooling is provided by a large internal rear panel fan. Rear panel DX connectors are five-way binding posts with removable red and black thumbscrews for stripped wire, ring terminals, and banana plugs. The unit weighs 6.4 lbs. and measures 7.2″ W x 4.4″ H x 11.2″ D.
Radio Today Guides from the Radio Society of Great Britain
The DX Engineering catalog will once again feature a nice selection of paperback Radio Today Guides for specific transceivers (IC-705, IC-7300, FTdx101, et. al.), including new ones for the Yaesu FT-710 (208 pages) and Yaesu FT-991A (176 pages) by Andrew Barron, ZL3DW.
These guides go well beyond what is provided in the manufacturer user manuals. ZL3DW takes a deep dive into how to get the most out of these versatile transceivers, including hidden features you might miss, best practices for setting up your rig, using the array of controls, troubleshooting, and operating in various modes. You’ll receive comprehensive, practical, and easy-to-understand advice covering all aspects of these radios, which are both available at DXEngineering.com (FT-991A HF/UHF/VHF Multi-Mode Transceiver; FT-710 AESS HF/50 MHz Base/Portable Transceiver).
You’ll find a wide range of other RSGB reference books, from Building a Transceiver to Stealth Antennas, at DXEngineering.com.
