HAM Projects

Optimization and Quality

Hamradio Projects

Here are my current Ham-Radio Projects to improve knowledge, expierence and to optimize the shack.

Remote ColibriDDC Receiver Project (April 2018)
The small Russian company Expert Electronics has developed and produced digital amateurradios. The main product of this company has been the SunSDR radio. Lately, Expert Electronics has produced a SDR-Receiver: the ColibriDDC SDR.
The ColibriDDC SDR is a high-quality receiver in mini size! The reception leaves nothing to be desired. The software ExpertSDR2 is very neatly arranged and easy to be operated despite the numerous adjustment options.

SDR-Play RSP1A as Pandapter for the IC-7700 (Dec. 2017)
It's just amazing to see the whole band on the panoramic screen while connected to the IC-7700 over Omnirig. Download the SDRPlay Panadapter Quide for many types of transceiver (ICOM, Kenwood, YAESU, etc.) here [1'326 KB]

The first version I was using only a BNC T-connector to feed the signal to the RSP1A and back to the IC-7700 RX-IN. I was told that in addition to the >3db signal loss I ran the risk of introducing all sorts of unwanted signals into the IC-7700 receiver. So I was looking for a powered lossless 2-way active RF signal splitter and found the "Boni AntennaJet AAS300D" from Bonito Hamradio. Installation was simple. I connected it to my central 40 Amps 13.8 V power supply.

Boni MagaLoop FX Active Antenna Test versus my Inverted-V Antenna (January 2018)
I made the tests at my home QTH to compare the signals with my current Inverted-V Antenna on top of my roof and the new Boni MegaLoop FX Active 80cm Loop on my balcony just 3 meters below the Inverted-V antenna.

Here are the audio files (13. Jan. 2018, 10:00UTC):
14.222 MHz - USB - 59 - CT1EHI - Loop [64 KB]
14.222 MHz - USB - 59+10 - CT1EHI - Inverted-V [187 KB]
14.222 MHz - USB - CT1EHI - Loop - Inverted-V - Loop [237 KB]

14.289 MHz - USB - 59+10 - LZ1833PSS - Inverted-V [147 KB]
14.289 MHz - USB - 59 - LZ1833PSS - Loop [228 KB]

7.131 MHz - LSB - 59+20 - DL8MLD/P - Inverted-V [307 KB]
7.131 MHz - LSB - 59 - DL8MLD/P - Loop [303 KB]

Summary:
It seems that my Inverted-V Antenna is performing great compared to the Loop. I've got no advantage from the Loop in order to receive a stronger or a better signal with less noise.

Project Clean up my Shack (Sept. - Nov. 2017)

- reduce overall noise with an excellent grounding
- remove all small 220V noisy power supplies
- use only high-end components
- for best usability
- for easy maintenance

- new Shack furniture
- new AC and DC (13.8V and 5V USB) Power Distribution and cabling
- new grounding concept based on a main copper plate bus
- new computer (USB & RS232) and network cabling
- etc.

Clean and ready to go ...
