Cheap GPSDO kit - a must have for service bench.

Sometimes we all need to compare quality of our equipment, make some tunning of circuits, or just check/recalibrate rig frequency. 

For those working on TRX repair good stable and accurate signal frequency is a must have. Unfortunately, modern (mostly from BY) cheap frequency counters using (as per description ) internal TCXO generators, but the truth is, they are not locked perfectly and from my experience they are "no go" for proper RIG tuning/calibration. All this lead me to "buy" some GPSDO. 

Because I am not happy "buying" things I can make with my own hands, so decided to buy a kit instead. 

Fortunately polish ham Marek SQ7HJB designed some neat GPSDO device with Arduino Nano, GPS module and SIS5351 with two signal outputs, and neat OLED display. Max frequency is determined by SIS5351 and in my case ends up at about 155MHz.

Completed PCB - pic source: http://sq7hjb.pl/index.php/mini-gpsdo/

 GPSDO diagram - pic source: http://sq7hjb.pl/index.php/mini-gpsdo/

Overall cost of this GPSDO kit (without Hammond enclosure) is ~ 50 Euros. That's not the price to make bank loan.     

Below You can see my approach to this nice piece of equipment, if You decide to make something similar I can help You with Polish language :-)

Below You can see a kit - THT version of PCB, Arudino, encoder, WaveShare GPS with ceramic antenna, OLED display and SIS5351 generator.

Comple GPSDO kit - pic source: https://radiohobby.pl/projekty/gpsdo-z-si5351-generator-czestotliwosci/

After soldering all joints, voltage regulator and pins ( which takes ~1hour and it's very easy ) we can power the device and check for proper voltages, non intentional shorts etc. If all is ok, now time to solder heart and brain of this device. Be carefull as all of them are ESD sensitive! 

Asembling instructions is VERY accurate and exact, unfortunately in Polish but this should not be a problem. All vital information You can see on RADIOHOBBY project page, if You need more info, mail me. 

You should end up with PCB looking something like that : 

 If all well GPSDO is running form first shot showing some information.




You'll see LED on GPS module lit (red one on pic above), and will start blink immediately after picking up satellite signal.

After some minute or two when generator will be locked at programmed frequency "LOCK" LED(green) will lit as well and after few (2-3) GPS count passes we can switch the display to show frequency correction. Small @ on the right show that GPS is locked, and accuracy is better than 1Hz.

There are several ways to program frequencies - with encoder, or with PC. If You are familiar with Arduino programming sources are available on project page in package. To be honest I get mine already programmed kindly by Marek (tnx a lot).  

4 memory banks for most needed frequencies can be programmed with multi encoder, which is also suitable for QRG step change, time zone settting and display switching.  

Two outputs of GPSDO can be populated with low pass filters - i.e one 10MHz filter for frequency counter clock, and second for frequency You need. Or - just leave the second one unpopulated - feed directly from SIS5351 output for various frequencies as I did. Also, if needed (as in my case) - I had to change GPS antenna for ordinary external GPS car antenna block with 3m RG174 cable.

All this fit perfectly into Hammond enclosure, but this depends on your choice.

In case anyone need more info - don't hesitate to drop me @.

Digging in the "salt mine"

 My friend Arvo ES1CW (R.I.P) said to me one day, that working with the QSL's card is like salt mine digging...well, Arvo was main ES (ERAU) QSL manager, so his salt mine was much bigger than mine. The only thing I have about, it's every QSL is like piece of crystal, keeping inside "moment" of QSO. Each one is different, and each one should have it's way to recipient. You can have e-qsl, LOTW - but it won't give You same personal memories when You keep paper card in your hands..

So if You have in your log S.E.S callsign 3Z95IARU (I know few of You 6m op's worked them) - You'll get your card soon (I hope). At least I'll do my best to make it happen. 

95yrs of IARU S.E.S QSL
  
Small :-) 31kg's batch just sorted for each DXCC. Guess which DXCC is won ths battle? 3rd column... yes, it's DL packet. Imagine how big it must be in Central PZK Bureau...?

2020 ARRL EME contest and 70MHz #JO57GG by Danish op's

Same as last Year, well known group of Danish operators will be QRV in ARRL EME Contest, on 144 MHz and 1296MHz band during 2nd weekend of October, 10-11 under the call OZ9KY.  



They will be located same as usual in JO57GG, at the Jorgen's OZ1GWD QRA. Although they plan to do extensive run in EME contest, in the meantime 70MHz operation is also planned for those who need this rare #. 

 Lot's of various equipment will be set up, so no doubt they will have fun :-)

Please contact Henrik, OZ8ZS with OZ2OE (inspecting the setup above) for sked schedule and more information.   

GL all !

New Polish 50MHz beacon

 On behalf of Jurek, SP3SLU I'm glad to announce following info :

From beginning of September 2020 there's new beacon SR3KWA/B active on two bands 50 & 144Mhz from permanent location in Turek, JO92GA. 

Working frequencies 50.345MHz and 144.463Mhz CW mode. 

Both transmitters are 5W output TX feeding Squalo Antenna on 6m, and Cross dipole on 144MHz. 

 
Location at Zbig, SP3GRE property, on local hilltop, overall height for 2m antenna is 158m a.s.l and little lower for 6m Squalo antenna (pic below).  

Both transmitteres were donated by "Polski Klub UKF" and adapted by SP5XMU and SP5MX. 

Initial idea of beacon - Jurek SP3SLU and Zenek SP3JBI, all work done by SP3KWA members and fellows from OT-27 (Southern Greater Poland) branch of PZK.

Any reports welcome - please send us note with your locator, equipment or just report SP3SLU@WP.PL

Tnx Jurek.
