Build your own HF balun
EA4EOZ
A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cable. From the RF point of view, the shield can be modeled as two conductors, the internal shield (the real shield, this is, ground) and the external shield, who is really far to be ground. In this way, your dipole has 3 arms, the two from the dipole and the coaxial cable shield (external face)

ApacheLabs Andromeda

ApacheLabs Andromeda is the result of a project realized by a young and innovative team of expert electronic and computer designers that has given birth to Andromeda, an innovative 100 watts HF + 6 m SSB, CW, FM, RTTY, AM and digital modes transceiver with top performances.

Andromeda integrates all the typical elements of an SDR, a software-defined HF radio: PC, display, DSP and RF are all integrated in a single unit for true stand-alone operation.

The front panel is fully integrated with THETIS software and offers state-of-the-art DSP with “conventional radio” usability.

The front panel features a VFO with high-resolution encoders, six dual encoders for a wide range of settings, and twenty-nine buttons. All encoders and buttons are programmable allowing the user to reassign them to other functions from a menu within THETIS.

Andromeda features a giant 7″ touchscreen display. A set of configurable “softkey” buttons at the bottom of the screen can be used to perform most of the user settings needed to use THETIS; other commands are accessible through configuration menus.

Also in the advanced stages of design is an ATU that will be provided as an add-on.

The Andromeda features an Intel i7 CPU running Windows 10, 8GB of RAM and 128GB SSD, three USB 3.0 ports, 100/1000 Ethernet port, HDMI port. Measuring 35x13x30 cm and weighing 6 kg, the Andromeda runs on 13.8 V

ApacheLabs disclosed that the delivery date for the first orders is estimated to be December 2020, January 2021.

Universal Radio To Close Store

Dear Friends Of Universal Radio,

Time waits for no one, and that includes Barbara and myself. We have decided to retire and our current location in Worthington will close on November 30, 2020.

Even though the store is closing we will fulfill all existing customer orders and have a large amount of inventory to close-out.

The Universal Radio website will be maintained for the foreseeable future to sell this remaining stock, publications and some select products. Unfortunately the lack of a store front showroom will preclude us from carrying some manufacturers’ products.

I am very fortunate to have been in the radio business for over 50 years, 13 at Radio Shack and 37 at Universal Radio. We have met many wonderful people along the journey who have supported me personally as well as Universal Radio.

It has been a privilege to have a continuous career in the fascinating field of radio since 1969.

Please accept our sincere “Thank You” for your support of Universal Radio for these many years, and for the months to come. Our new address for correspondence and mail order is below.

This is not a store front.

Universal Radio Inc.
752 N. State St. Unit 222
Westerville, OH 43082
Phone: 614 866-4267

Thank you. 73,
Fred Osterman N8EKU Barbara Osterman KC8VWI

Universal has been offering the finest in amateur and shortwave equipment from central Ohio for over 60 years. Universal was founded in 1942 by F.R. “Gibby” Gibb W8IJ. Universal Service, as it was then called, was located on North Third Street in downtown Columbus, Ohio.
