PRV-10 height finding radar, ZZ Exclusive modell, 1/72

Recommended Posts

a little known model I suppose...

the PRV-10 is a height finding radar for incoming aircraft. It was used in a Sa-75 battery (Sa-2), as an aid for the SNR-75 Fan Song attack radar.

This last one had the disadvantage of a very narrow searchbeam. This radar aided with broadening that view to make searching the targets more easily.  Range was approx. 296km.

 

The actual PRV-10 radar

More specificaties:

Frequency: 2 Ghz (E-Band) 
Power source: 2 MW (peak) 
PRF: Resolution: 3 km, 500 m height 
ON/OFF time: unknown

Detection fighter sized aircraft at 500 m height: unknown 
                                                     10000m height: 300 km

the housing: I added some tin to the PE-parts to make them look less flat :

I have to say that I admire your etched brass soldering skills. That's looking really good.

Soldering PE is simply a must. Beautiful to watch this work from you, as with the little TKS Tankette from another thread, it just looks the part and its very solid.  

It shall be a practical modeling goal for 2020. I used to solder a lot, I just need to pick up that gear again.

Every time I see a thread like this, I promise myself to do it that way again and again, but no.

Very interesting build, will follow along.

 

Kind regards,

 

Robert Jan

Building goes slowly lately...

 

Antenna received it's cover plate:

It is a PE mesh with fine diamonds. I've cut the part in 3 parts, not alone for handling, but also to save a bit on material. I hope the seem won't be that visible after painting... It has been filed to fit the frame after soldering... Also the hinges received some solder, not to make them rounder, but to reinforce them.


The antenna-housing is also as good as ready. Cables, receiver, etc are added, only the entrance step needs to find it's way onto the assembly, but I thing this will be done prior to painting:

The frame is now only missing it's cable for connection to the towing truck. Other cables and the steering mechanism are added:

The connector for the missing cable has been made (with a file, no lathe...) size is ø1.7 x 2.3mm ahum:

To the next which will be primer and basecoat hopefully...

Thank you both

 

Tried again with my new AB (H&S infinity 0.2mm nozzle), but it feels like I can't do the same as with my old one (a very cheap AB from ebay, 0.3mm nozzle) and it is hard to paint some variation in the shades..

 

Antenna in basic colors, only 2 holes gor filled by paint, some slight retouching needs to be done

The housing needs a second color:

Some handles broke of this one, just to be determined to add some lighter colors to the top surfaces

Very nicely done, the dish looks great. I've never soldered anything in my life, but sure looks like a very useful skill.

I have some mixed feelings about this, but I am curious about your opinion.
