Re: 29-Dec-2019 3cm opening

Nicholas Shaxted
 

Conditions are dropping now that operators are appearing.

 

Overnight some insanely strong signals from the beacons DB0GHZ and PI7ALK.

Along with F5ZTR, OZ5SHF, DB0VC, OZ7IGY (up to +7dB pi4).  

GB3LEX and GB3MHZ received a few minutes ago (10.15 utc) looking out over the North Sea at 52 deg etn along with PE9GHZ and PI7RTD on the same heading (rain bearing cloud)

I am glad to hear one of my former local beacons (DB0JK) has been heard in the UK. It should appear frequently but it does have a tendency to decide to wander about the band in “warm” weather. It can appear on 10368.843 for weeks during the 30+ deg summer heat. It gets hot in the Colonius broadcast tower.

DB0GW should also appear and am surprised it has not been heard (.852 to avoid GB3SEE).

 

Have fun all I have used my allotted time for the day 😊

There were some amazing sigs on 3cm last night, HB9G at 995km, plus the beacon near Orleans and DB0GHZ. Only worked one station in the JA session, but Maurice was 20 over 9 at one point. I could copy him well while he was beaming east from JN18 to DL3IAE

I am tied up with visitors today so probably won't be able to play

I hear DB0JK beacon on 10,368.864 MHz. 23cm in reasonable shape too.

Hi Martyn.

I have one too.. .. Its a two stage 1w PA for 13cm. I use it all the time to talk to you on 13cm It drives my SSPA.

I have seen two varations of it I think the earlier one used two similar devices and the later one had  much more chunky output device marked 5A 16B (MGF0905A). Mine is the early beta test one. Input device TGF2960 (SHF-0189) and output device TGF2961 SHF-0289

Nice little module to produce 1w on 13cm from 1mW.Beware max drive 4mW. Dont forget to apply the bias suppy!

Hope this helps

Where is everybody tonight on 13cm? I just worked ON4CJQ/P for new country and locator on 13cm

Re: ADL5375 Chips

Andy G4JNT
 

So far had expressions of interest (sent as PMs) for around 5 chips, which makes it worth ordering ten to benefit from the bulk discount.   So I'll put in an order either tomorrow or Monday, (depending on countryside / New Forest walking programme :-)
I'll include your TCXO as, well Barry.

I did my own PCB for this IC; its quite a simple bit of circuitry.  Photo in the ADL5375 Tests link sent earlier

Is any one interested if I buy more than I need myself ?

These chips are quadrature upconverters that operate over 400 - 6000MHz .  I/Q drive is differential, 0.5V pk-pk (each side, so 1V diff pk - pk) centred on 1.5V  That means it is near enough compatible with the dsPic D/A converter with direct connections to its D/A output pins. I'll be  using it with the G8ASG Weaver generator  http://g4jnt.com/DsPIC_Weaver_DUC.zip   (update in the next RadCom)

Re: 3.4GHz bits

John Worsnop
 

I'm always up for a 9cm test. Just email me on the reflector so everyone else knows you're QRV. The kit lies gathering dust for most of the time. I often see enhanced propagation from the Midlands and PA beacons. Usually rain or aircraft scatter. I can also be QRV off the moon with some notice. The fact that I've had more EME QSOs on 9cm this year than on terrestrial is a sad reflection of the lack of use of this threatened band in England. I'm completely agnostic as to modes. CW, SSB, JT4/9. I run 20W to a twin dipole feed sharing my 60cm dish with 10 and 24GHz.
