This Transceiver does it's job very well since 1997!

max. 5 Watts output

Kenwood TH-F7E

Nice Transceiver with a missmatched antenna.
Not usable for amateur radio frequencies. So I had to buy an appropriate additional antenna.
Not a good advertising for Kenwood!

SWR-Meter RS-1000

SWR-Meter: Maas RS-1000

This RS-1000 is equipped with two separate input-ranges for different frequency-ranges.
Frequency-Range: 1.8 - 160 MHz / 430-1300 MHz
Power-input: up to 400 W (switchable 5 W / 20 W / 200 / 400 W)
Min. power for SWR-Messurement: 0,5 W
@ 5W Range: +/-5%
@ 20W Range: +/-7,5%
@ 200W Range: +/-10%
@ 400W Range: +/-12,5%
Insert attenuation: 0,2 dB (1.8 - 160 MHz) / 0.3 dB (430 - 1300 MHz)

SWR-Meter by DJ9PK

SWR-Meter by DJ9PK

It is a Standing-Wave-Ratio-Meter (SWR-Meter) and Wattmeter (also PEP) for Shortwave (1,8 - 30 MHz) with good accurency (typ. 5%) and a great range of measuring (0,5 - 250 Watt).
A frequency counter (up to 50 MHz) is also implemented.
If you wish this SWR can also be issued with 800 or 30 Watt measuring range.

Digital Modes Equipment

My TS-590S is directly connected to the computer via usb-cable without any further equipment. It works very fine and without any problems in all digital modes I am on air.

With my TS-2000 I use a separate soundcard-interface to work in digital modes (see below).

Lightning Warning

Gewitterwarner GW1

Lightning-detection up to 40 km
Detektion for lightnings against ground or cloud/cloud
Blanking functions for technical incidents like switching operation and other interference pulse / glitches. Sensitivity adjustment is available, so that it can be used to detect lightnigs within buildings or outdoors. 3 Open-Collector-switchable outputs for warnings, lightning events and all clear signal for dissapearing thunder are configurable as impuls or steady output

Available at ELV

Additional Measuring Equipment

Dummyload with attenuator


100-W-Dummy-Load with 40-dB-output-attenuator.
It is usable up to 150 MHz and a input-load up to 100 W for measuring purposes over a -40-dB-output (BNC)and N-Type Input-connector.

It is a very usefull for my measuring purposes and it's often used!

Several Attenuators


Kit for a 30-dB-Power-attenuator
max. load: 5 W (shortly) Impedanz: 50 Ohm


Different attenuators with 3 dB, 6 dB, 10 dB, 20 dB, 30 dB.
0-2 GHz, 50 Ohm, BNC, 0.5 to 1 W




It is a very good and usefull measuring equipment for my purposes!

Inductivity: 1 nH to 100 mH (with high metering frequency)
Inductivity: 1 µH to 100 H (with low metering frequency)
Digital resolution: 4 Digits
Supply Voltage: 5 V (over USB- or DC-Connector)
Dimensions: 81 mm x 47 mm x 30 mm " - Box73">

Antenna Analyzer



I bought this analizer second hand. It helps me to design my homebrew antennas.

My summary: It is not the very best and accurate analyser but it's ok for the most of my applications, so far.
One time or other I intend to get a more reliable vector-network-analizer.

MFJ Enterprises Inc.

WiMo Antennen und Elektronik GmbH



I received my new analizer in Dec/2014 and I am very fascinated about this instrument.

My summary: It is a yery cute appliance and it does a very fine job, as far as I can say up to now.
I will test this device in the near future and get more aquainted with it.

There is more in this instrument than meets the eye :-)

This device is developed by Melchor Varela, EA4FRB.

Signal Generator


The XG3 is a programmable signal source.
Miniature RF source for shack or field use - Synthesized signal
1.5-200 MHz range, with a typical resolution of 1-24 Hz. (Up to 1400 MHz via harmonics)
12 programmable bands for 160-2 m (Or use as arbitrary memories on any frequency.)
Four calibrated power output levels: 107 dBm (1 uV), -73 dBm (50 uV, S9), -33 dBm (S9+40), 0 dBm
CW and RTTY Beacon Modes
The XG3 is a programmable, 160-2 m RF signal source with four calibrated output levels. It's ideal for receiver calibration, sensitivity tests, signal tracing, and as a VFO for home-brew projects. It's also useful outdoors-for antenna evaluation, field strength measurements, micro-power cw beacons for T-hunts, etc.
The XG3's serial port allows you to use a computer to set up its frequency and output level, assign frequencies to band switches, and set up sweep step size and rate. You can use the supplied PC software, or write your own XG3 applications.

Power Meter


The PM4 is a Dual Channel 500MHz RF Meter
It consists of two main parts:
- the Graphic CPU-0613 and
- the PM4 Sensor

It measures power levels from abt. -70 dBm up to less than 0 dBm (1mW) at a frequency up to 500 MHz.
I like this instrument and it's fine to assemble it on my own.

Thanks to the guys of Fox Delta for developing those devices.
