Baby steps to MK-1 - General Coverage Receiver

Baby steps to MK-1 Presentation: Click Here (MK-1.ppt)

Hello Everyone,

We would like to introduce a new receiver to the family of receivers. First, we had the GR-40 which was a 40-Meter Rx. Then we have been busy with building a GR-20 Receiver, which is a 20 Meter Rx.

Then got us thinking why not build a general Coverage Rx. so that we can have multi-band support. Well these are the baby steps or stepping stones to building a multi-band Rx. Introducing the Mark-1 Receiver.

The MK-1 Rx. presently is covering a range from 1.5MHz to 7.5MHz. We have received a lot of DX on air and the gain is quite good.

More tech details and updates coming soon. Stay tuned.

GR 20 UPDATE

As per our Guru VU2VTM, OM Marcus (popularly known as Indian Marconi). We should always make more than two to three units to conform the repeat-ability of design.

We found 18.432 crystals is not easily available which were used as IF Filter. So we switched over to 10 MHz IF and anyway 10 MHz IF for 20 meters is standardized in world famous BiTx 20 meter TRx developed by our good friend OM Farhan VU2ESE. We made three GR 20 and here is the photo

The sample stations received: VU2AU, VU2OO, VU2RAK, ER4(Ukraine), VK6 ( Australia ), VU2KNN, VU2WWF etc.

Simple 20 meter drooping dipole is used. Here is the photo
