Hallo,
als Info:
habe gestern den OCXO (Rakon 25MHz 3.3V 0.5ppm 14*9mm Square Wave HCMOS OCXO) über ebay erhalten und auf dem Adapter von PCB V1.2 aufgebaut.
Signal ist sehr sauber, Strom im warm-up 320mA, im stabilisierten Zustand (nach 2 - 3 min) 120mA.

Hello Artur,
is there an article name for the weatherproof housing?
What weather protection is provided for the patch antenna?

Hello Artur,
is there a proposal for dimensioning for the PA-drossel 5nH?
Thank you

Hallo OMs,
heute mal kein technisches Problem.
Artur hat ja die Entwicklung des Projektes bis zur V1.6 vorangebracht. Die diesbezügliche PCB und weitere Teile sind bei ihm erhältlich (mit der Lieferung zur V1.2 sehr gute Erfahrungen).
Wenn auch das ADF-Board trotz Nutzung eines programmierten ATTINY von Artur noch nicht läuft, andere Baugruppen funktionieren gut, habe ich die V1.6 bestellt.
Vielleicht geben sich andere OMs mal einen Ruck und "outen sich", wenn sie sich auch mit diesem Projekt beschäftigen.
Da könnten wir in Erfahrungsaustausch treten (mit DL2GMI klappt das schon hervorragend), Fragen sammeln und so ein positives Gesamtergebnis für alle erreichen.

While preparing the BOM to order some missing parts for my next try to Build the TRV2, i´ve collected some questions:
1) I Have problems to find the Coils 18n and 7n5 in size 1008 - can you tell me a company who can deliver those? I´ve looked at Digikey, Mouser and Reichelt
2) The Diode BAT54S/A: Which type is the correct one - in the shematic it is a BAT54S, in the BOM a BAT54A ? I think BAT54S is correct ?
3) Which type of BC847 we´ll need - BC847A, B or C ? I have one C-type here.
4) Do you have a shematic and Bom for your own ADF-Board ?
5) Do you bought the LED at KAMAMI.pl ?
6) For example, is this Coil correct: Mouser 710-744762212A for 120nH ?
Thank you!

Many Thanks!
But i see that the Coils you have linked to are size 0302 or 0805 or 0605 and not 1008 as it is written in the BOM ?
Thank you for the Shematics of ADF-Board, i will apply the components to my own BOM.

Thank you!
I´ve some more questions - in the BOM i´ve found 510R, 2 pcs. 220 (Shematic 3 pcs), 51R vs. 50R - which is the correct one - the PCB or the BOM ?
I´ll now order some parts by E-Mail at your side.

Artur,
this week i have received the Parts/PCB/case and today the LNB with Poty - many thanks for the quick transfer! I´ve already started to solder the parts.
Addititional to my questions in the thread before i have one missing value on the additional PCB for VCTCXO.
See the picture for detail.

Artur,
two more questions. Sorry for that, but the project makes big steps at the moment :-)
1) I have decided to use the Mouser VCOCXO (815-AOC2112VAJC-25C), i hope this is better than the TCXO from Aliexpress and the right decision. Do you agree ?
2) The AG303-86 is not longer available at Mouser, so it could be a problem in future... I have contacted mouser already.

Hi Artur,
Hi community,
the AG303-86 is not longer available. The new one is the AG303-63 with new footprint and size.
The Building of the TRV2 with PCB 1.6 is nearly finished, except some Coils with special Values and the AG303 - my special thanks goes to Michael_K who has send me one.
Now i make the BOM for the additional ADF-Board. Please check the attached BOM and tell me the mistakes.
And, can you please attach a Placement plan of the parts ? The assembly imprint is not readable (SMD size 0603...).

Connect a 10K resistor with + 5V to the point on the photo. The LED should light up.
|
|
I have the same problem as Michael_K. I have the BAT54S installed, the imprint is "KL 4"
The TX/RX-Switching is not working. With the resistor described as in the Photo the Red LED light up.
Where can i search the issue ?
