Microwave advice Nera link equipment

[gu6efb]

Hello

I have just removed two microwave link system the data plate says freq 24.25 Ghz to 26.50 Ghz
I have a full system both ends the TX/RX unit complete with 30cm prime focus dishes. The link was operating over a 60KM path. I have also all the power supplies and POE switches and controllers.
The equipment was made by Nera and has the number FL26AAA0A R1K 40103565
Has anybody have experience with this equipment and converting to amateur use?

I also have a full system from Nera for 7 to 7.6 GHZ as above and 60cm dishes again could they be made to work at 6cm?

I have no experience at these dizzy heights so any advice gratefully received.

Hi Keith,

Having looked at similar systems the general feeling is that only the dishes are worth keeping. Most of the gear is very wideband, programmed for frequencies above and below the amateur bands and if built in the last 15 years highly integrated. If it is older than that there may be some mixers / amplifiers connected by semi rigid which are worth recovering...

Hope this helps.

Hi Noel

Many thanks for the reply. I will take the covers off and see what is hiding inside.

Hello Keith,

That's an interesting setup you have there! For the 24.25-26.50 GHz system, it should be possible to convert it for amateur use on the 24 GHz amateur band, though you may need to make some adjustments to the TX/RX units, such as tweaking the local oscillator or modifying the waveguide components. It's also worth checking the output power and ensuring it's within legal limits for amateur use.

For the 7-7.6 GHz system, operating it on the 6cm (5.65-5.85 GHz) amateur band could be challenging due to the frequency gap. Modifying the equipment for lower frequencies might require significant hardware changes, especially in terms of filters and amplifiers. However, some amateurs have successfully repurposed commercial microwave gear, so it's worth reaching out to others who may have worked on similar conversions.

Good luck, and I'm sure others with more experience will chime in!
