Re: Rotator question

Hello John ('XDY, this time!)

Fitting a shaft encoder into a '2051 shouldn't be a big problem. I've played with magnetic encoders while (too slowly ...) developing a new EME dish mount but I'm certain there would be no problem mechanically, with that rotator, providing the end-float problem was considered.

I'm very happy - so far! - with the OE9PMJ az-el controller, but I'm sure that for a simple azimuth controller an Arduino based approach would be pretty simple to implement.

I have been using a Prosistel 2051 for nearly 10 years now and its proved its worth. It fitted the existing Altron head unit with no problem.  Like others I'm on about my third indicator pot and am considering changing to an absolute encoder and rebuilding the controller to suit, but that's not a simple task. I believe Prosistel do now make a version with a shaft encoder with 0.1 degree resolution. The PstRotatorAz software package from YO3DMU works well too.

Hello John,

I used a Prosistel 2051 to turn some big-ish HB yagis when I lived on an exposed site in NW Carmarthenshire. I wish I hadn't sold it! Like Nick, I did have problems with the direct drive of the readout pot resulting in its eventual destruction. It just needs a flexible shaft coupler eg.  a length of reinforced neoprene tube, to take-up the end float which did the damage. Nowadays I'd replace the pot with an absolute encoder and modify the control box accordingly.

Hi John,

 

I use a ProSisTel PST61 and have had it for around 10Years now. As you may know I live in a very exposed site on the eastern edge of the Pennines and have a large antenna array and have over the years that I’ve lived here have destroyed several of what were considered “Large” rotators. The PST61 has withstood all that the Pennine winds have tried to do to it and I’ve had no mechanical failures with it. It easily resolves to 1deg with my 80Cm dish on 10Ghz and I’ve used it successfully for several years now. The only problem with it is the pot used to feed back the azimuth readout which becomes noisy on a regular basis and needs replacement. Mine currently needs this done for the third time and I intend making some modifications this time which are supposed to alleviate the problem..........We will see! You may find that the PST61 may be too large for the Versatower headunit, mine’s home built and somewhat larger, so you might have to consider the smaller PST2051 to fit.

 

Good Luck and 73s

'Evening all

 

What rotator do you use at home for the microwave bands ?

 

I have a Yaesu G-1000 here. It's man enough for my couple of dishes (2m and

1m) and a small yagi, but it has a backlash of about 1 degree. That's not a

lot of help when my 3cms dish has a 3dB beam-width of around 2 degrees !

 

Whatever I get, if I do change, will have to fit a standard Versatower head

unit.

 

Most makers don't specify the backlash, but I'm expecting those rotators

which use a worm gear off the motor will be better ?

 

A cue for tales of rotator woe perhaps ........

Hi John,

I am working on a rotator with a 100:1 worm gear driven by a stepper motor.  Not sure of the backlash at present but I intend to use it for Yagis on the tower so there is no low backlash demand.  I hope to use a similar system on a big microwave dish (2.4m) so will need good accuracy but as it will be moon tracking in one direction only the requirement for low backlash may not be too severe.

For an off the shelf soultuion you could look at:-

http://www.prosistel.net/
click on the union flag.

or
https://smart.antenna.it/
Not sure what would fit in a standard head unit but mine is like the GE 2500 NS and the gearbox has been modded to fit.

My first contact on 2.30 GHz NoV band

Graham - G3YJR
 

I did an on-air test with Keith G4ODA and it worked, so he became my first contact on the NoV band.
I'm running with a BPF now; the loss is a bit more at 2.30 than at 2.32 GHz. I run both transmit and receive through the BPF. On receive, I hope this keeps a lot of out-of-band signals from the Crosspool transmitter masts out of the pre-amp.

Something like a 3 section post-coupled waveguide design.    Or perhaps an evanescent one in WG20.

Unfortunately the need to do them with SMA connectors / probes makes the setting up more tricky than in WG alone.

Pity I have no network or even scalar analyser that goes to 10GHz, otherwise it might have been a tempting project

Re: G3WDG Boards

Andy G4JNT
 

The other option is image cancelling I/Q upconversion.     The 'DGU board used this with a 144 IF and managed better than  15dB image rejection, which then meant a more relaxed filter spec could be used.

I took his design (had a spare Tx board) and carried things further, feeding the mixer diodes at baseband for direct upconversion.  Now, since the image lies on top of the wanted signal, poor image rejection doesn't give OOB spurii and at -15dB doesn't degrade the wanted signal by too much.   It's also quite easy to trim I/Q balance when you're at baseband.

And these days, you can get  I/Q baseband SSB a lot easier:   RadCom April 2017 page 27    and http://g4jnt.com/DsPIC_Weaver_DUC.zip
