Re: Question ....

Brian Flynn GM8BJF
 

Hi  Gordon,
 I have been using an ADF4351 t generate 27 MHz for an octagon. I am programming it with a Arduino Pro-Mini. I copy the the "sketch" below if that is useful. Also I recently bought another ADF4351 board on Ebay from this seller.
https://www.ebay.co.uk/itm/35MHz-4-4GHz-PLL-RF-Signal-Frequency-Synthesizer-ADF4351-Development-Board-HighQ/253611628632?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2648
It seemed to be the cheapest one around. It arrived promptly and I put it through its paces testing it with the AD evaluation software and a Cypress board. The only thing I did to it was to add a bit PS decoupling to improve the PN to what it should be.
The adf4351 was used to generate 54 MHz from a 10 MHz reference which I then divide by two. It allows the 27 MHz to be "tuned" around.

The code programmes the ADF4351 and then puts the Arduino to sleep to reduce the chance of noise of the SPI bus.

* Sketch for controlling an AD ADF4351 synthesiser

* Arduino program and an SPI  enabled peripheral chip.    
*                                                          
* The routine reads in the hex vales from the sketch and sends

*                                                           
* The SPI library uses pin 13 of the Arduino Uno for clock. 
* Serial data is sent out on pin 11.

Hey Conrad,

 

i'm sure it isn't a PLL version, i think you have this one:

 

Octagon Optima OSLSO Single Slim LNB 0,1dB

 

Today i did some tests on rx the EB high beacon:S/N 22dB with Triax 95*85 dish, Octagon out-of box PLL LNB; and some other modified LNB's  with the board from a Octagon PLL connected to them via sma, into a SDR RTL dongle. Polarisation is H. No reception on the EB low beacon due to some exremely high noise level, so need that to find out .

I have in my possession a single output Octagon OSLSO and I got the lid off only to find that the Xtal is on the underside of the single PCB. I have seen details of dual Octogons but I am not sure how to get this board out.  I presume that the edges cannot be soldered so maybe it is just the vias that need to be desoldered. I'll start with desolder wick, I hope that this works!

Re: Octagon Quad LNB green OQSLG

Paul G8KFW
 

Hi all

There appears to be several variations of the Octagon with  OQLG going for  £ 13  and OQSLG  going for  £18 

 

There also references to  Multi Switch    HQ   and  HDTV     I assume the later are just advertising

So is the  one below  the one we should be using

 

 Octagon Quad LNB green OQSLG HQ 0.1 dB NEU OVP

You can search for Inverto or Goobay LNB's too, they have also PLL.

Hey Conrad,

i'm sure it isn't a PLL version, i think you have this one:

Octagon Optima OSLSO Single Slim LNB 0,1dB

Today i did some tests on rx the EB high beacon:S/N 22dB with Triax 95*85 dish, Octagon out-of box PLL LNB; and some other modified LNB's  with the board from a Octagon PLL connected to them via sma, into a SDR RTL dongle. Polarisation is H. No reception on the EB low beacon due to some exremely high noise level, so need that to find out .

I have in my possession a single output Octagon OSLSO and I got the lid off only to find that the Xtal is on the underside of the single PCB. I have seen details of dual Octogons but I am not sure how to get this board out.  I presume that the edges cannot be soldered so maybe it is just the vias that need to be desoldered. I'll start with desolder wick, I hope that this works!

Hi Conrad,

Question ....

Gordon REASON <gordonj.reason@...>
 

Needing a >800m Mhz LO .......

Has anyine been successfull , with a Arduino Nano , with one of the Chineeees   ADF4531 boards .

And who is the best source of those boards ......

My brain is'nt capable of creating a sketch , so some help needed .

Hi Conrad

 

That rather looks like a DRO based LNB.

Re: Es'hail-2 NB transmit

Conrad, PA5Y
 

I have to agree with Dom. I have many DF9NP synths in use, 15.6 MHz for my TS2000x, 116 MHz for injection locking 2 x Anglian 2m transverters, 101 MHz for reflock on Iceni, 42 MHz for a 4m Anglian and a GPSDO for 10 MHz reference. They all perform very well and have good PN at the price point.


I have PN plots of some of them done on an FSUP, in each case I used the high stability 10MHz reference on the instrument.

Hi Pete ,

have a look here
http://www.df9np.de/
www.df9np.de
Homepage of DF9NP JN58LU DOK: B15. Welcome to DF9NP`s HAM PLL Webside ! I am QRV on 2m , 70cm and 23cm focused on DX and weak signal. On 2m 230 Squares and 47/3 DXCC Europe, Asia, Africa


the PLL's can be ordered programmed up to 4 different frequencies for a
single board. Price is low , in fact , it is difficult to save money by
building it yourself.
This man is very helpfull and serious

there are a 2.4Ghz simple transverter , with a companion amplifier using quite low cost MMIC. On RX , a 10Ghz converter going to whatever IF one needs.

Lo's are DF9NP , but one can build his own , and the RX side migth be cheaper too by using a PLL LNB.

Hi Barry,
Have seen the tone steps at approx 1min past the hour and 1min past the half hour this morning , with several step sequences repeating each time .

These 4 tones seem to occur just after the hour and maybe at other times too. Sync signal?

The webSDR I mentioned in my posting yesterday is a good way of checking this and any other behaviour. Yesterday the main beacon frequency seemed to be moving around at times in discrete steps - not drift.

Ah !
I use a 27MHZ locked Octagon LNB , so 10368 = 618MHZ output.

The Eng Beacon is on 10706MHZ , so 338MHZ above 10368MHZ and displayed on my Airspy RX at 956MHZ ( Airspy is not externally referenced at this time , so displayed carrier frequency is slightly LF of 956MHZ) .

This normal  carrier occasionally is shifted in three steps , symetrically +/-   , but lasting for maybe 3 seconds .

Have you seen this behaviour ?

Hi Matthias,
I think the one at 956MHZ , nominal .
The additional ones , when running ,are showing in the waterfall equally offset above and below this main carrier .The lesser continuous amplitude lines HF of 956 MHZ are artifacts .
May be local cellphones !
Fortunately the narrow and wideband transponder output areas are free of add ons .

I see the occasional add on carriers around the basic one at 28dB/noise .

It is the Eng Beacon ....?   (SDR is running unlocked )
