Are you frustrated or having trouble trying to hear signals on the lower HF bands? The New Mini-Kits EME234 Magnetic Loop Amplifier Module might be the answer. Extensive testing in recent months has confirmed how effective a magnetic loop is at being able to actually hear signals on the lower HF...

The Mini-kits EME182 HF 100kHz to 80MHz Active Antenna Module has been updated to make it much easier to construct. The New EME232 Module still has the same excellent strong signal handling with an OpIP2 of +79dBm and IpIP3 of +39dBm. This is equivalent to most commercial designs at a fraction...

Recently we have had a number of enquiries about fake Mitsubishi modules and RF MosFETs, and I can assure our customers that we only sell genuine Mitsubishi manufactured products from Japan. It appears that the Chinese may have reverse engineered many modules and MosFETs which are being sold on ...

There has been an increase of interest in FM Amateur Television recently in Australia and Europe, so we have now produced a New 2.3 to 2.5GHz 12 to 13cm band FM ATV TX version of the popular 1.2GHz TX. FM ATV compared to digital TV is much easier to transmit as it does not require linear amplifie...

A very busy day today making up 36 x PGA-103 amplifiers for a commercial job. There are 16 parts on each board that's 576 parts placed onto the boards with tweezers and around 30 solder joints per board, that's over 1000. It took around 5 hours and I still have to solder connectors on the boa...

We have added many new products into stock in the past few weeks including Epcos / TDK Ferrite cores that are suitable for suppression of noise, and for use as chokes in power amplifiers on 137 and 472kHz. I have tried to keep the part number generic like the Fair-rite brand with T157 being a 1...

The Mini-Kits 20dB Directional Coupler Return Loss Bridge module Is ideal for checking the return loss measurement and impedance matching of the input and output of amplifiers, filters, and antennas. The module uses a Mini-circuits ADC-20-4 coupler that has a 5 to 1000MHz frequency range and has...

With recent WSPR tests on the 630m 472kHz band using only 5W into the very inefficient resonant antenna, a problem has been found with causing interference to the ADSL modem that causes erratic performance with poor and intermittent data throughput. Another Ham has also found the same issue and ha...

The final version of the 472kHz 630m band Transverter Kit is now in stock. In most cases you can use an existing HF dipole like a G5RV as a top loaded vertical, and a series Inductor of around 500uH on a low frequency ferrite to get resonance on 472kHz. With WSPR expect stations to hear your sig...

Built up a quick variometer and matching transformer for 472kHz this afternoon and got an extra 5 to 7dB sig to noise. With the New EME223 472kHz Transverter and 5 Watts, it might now be enough to hear on WSPR interstate.
