I heard there is a downconverter in the pipeline,
when will this be available?
Kind regards

There was one, but we can’t make the numbers work for a reasonable retail price. Instead, we’re working on a radio that can tune to L-band without the need for a downconverter.

But! We do have about a dozen downconverters in stock. They are proto-designs, but tested and operational. Feel free to make an offer.

Syed Karim,

Thank you for the fast reply.

Wat about actual cost+ 50 %, that won`t hurt ,I think:relaxed:
That wil linclude a copy of documntation.

Kind regards

So that everyone has the information, we can offer the downconverters for $75 each. However, these are protoboards, so unfortunately, there is no documentation to speak. Only a very simple set of information, such as the LO and target gain.

Hi Syed,

What’s the rough spec of these units?

Cheers
Andy

sorry for the bump but , did you happen to sell all your prototype downconverter boards ?

We have a few left, but we can’t offer any type of warranty on them because they were made as prototypes.
