FAQ MKU UP 2424 B and MKU LNC 10 QO-100

Please note that the Up Converter module MKU UP 2424 A is no longer available.We have a new model MKU UP 2424 B with great enhanced features:

• includes additional module for optimized frequency generation
• synchronization by external 10 MHz-reference signal ( SMA-connector )
• enhanced frequency stability (+/- 0.5 ppm between 0°C and 60°C )
• various IF-frequencies in 2m-  and 70cm ham radio bands

 

As requested by many users of QO-100 the new MKU UP 2424 B  will come up with a 10 MHz reference input to synchronize the LO frequency

You can use the Gain control to adjust the output power. With a 144 MHz input power of approx. 500mW, the 2.4 GHz output power is approx. 400 - 500mW.

Please attach the MKULNC10QO-100 as close as possible to the duo-band feed of DJ7GP. The connection is best with using a piece of semi-rigid cable that is as short as possible and has an SMA connector on both sides.
For connection to our LNC, please use an SMA connector male, on the opposite side the suitable counterpart to the duo-band feed.
Please make sure to use a high-quality semi-rigid cable and connector, otherwise the sensitivity of the LNC suffers.
From the LNC output, you can pull the satellite cable into your shack then.

Please note that a 50 Ohm coaxial cable must be used for the MKUUP2424B, SAT cable is not suitable for this purpose. Good coax cables would be, for example, ECOFLEX 10 or ECOFLEX 15 to keep the attenuation from the shack to the antenna low.

We recommand to use "HTERM" but other programs should also work.
For a detailed description please have a look in the manual of MKU UP 2424 B.

Please note there is no protection against high power. Please always keep input power max. 5W. Protection circuitry
against bad VSWR ( e.g. antenna ) and overtemperature are integrated in the up-converter.

We did not plan to build a weatherproof case for the Up converter.
The first tests with Es'Hailsat have shown that it is possible to have good signals with 10W transmission power. The up converter makes 20W, so you might want to consider installing the up converter under roof, and to connect with the antenna with a good coax cable.
