Artur,
one more question again:
The OCXO from Mouser (Datasheet https://www.mouser.de/datasheet/2/3/AOC2012-Series-1545756.pdf has a power consumption at startup around 720mA, but the LP2985 3V3 can only deliver 150mA with a maximum at 350mA.
Can this work ?
And, is the SMD-mountd OCXO really connectet to the 3V3 line, not to the +6V or +5V line ?

Ok, which solution do you prefer ?
Which diodes i should use ?
I check all the existing XO´s here and than, maybe, i will ask again

Hello Artur,
2 questions about the TX branch of the TRV2:
1. what is the reason for the use of the SF2124E in the TRV2 compared to the TA1070A in the TRV1
2. from the layout of the PCB - can you also use 2 transistors in the PA in parallel?
Thank you

Hello Artur,
to the PCB V1.3 in the AMSAT forum I have the following questions:
1. there is a picture for this PCB to see the changes to V1.2;
2. What is the tup of the VCOCXO? where can it be procured?
3. are the adapter PCB for the VCOCXO available individually?
how much it costs incl. shipping
Thanks

Artur,
i have one more question, this time about the chokes 47µH in the 12V/1A-Powerline and the Line to the Poty:
I´ve installed a ferrite inductor with 47µH and 150mA, 11 Ohms with Size 1008. Is it OK or should i change those inductors, and if yes then please give me some examples.

Re:New TRV using ready module RX-TX-switching
« Reply #35 on: 19. June 2020, 16:27:47 »

Hello Artur,
the RX-TX switch does not work on my TRV2. Scon in RX mode, the voltage +RX5V is not generated.
I suspect the TLV2231.
My question:
what voltages must be attached to pins 1, 3 and 4 of the TRV2231 in RX mode or generated on pin4?
Thank you

Hi Artur,
thank you for the answer.
YES I used the BAT-54S.
The imprint is: KL-AD

Artur,
thanks for your reply.
One more: Do you have a drawing of the heat sink for this Transverter? I have contact to a metal construction company, they will make me a new heat sink because the heat sink from the Transverter 1 is bigger than for Transverter 2 and only has two holes for screws.
Actually i wait for the 3V3 VCTCXO from Aliexpress you´ve mentioned here: VCTCXO generator 0.5ppm 2.00 $: https://aliexpress.com/item/33013343039.html.
And i have to order one chocke 47µH and 2 pinheaders 3fold for the ADF-Board, which i have already received last week.

Hello Artur,
unfortunately no positive results yet.
A question about the LED:
what kind of type is this? In the circuit with the resistor 10k and a standard-led flows a current of 370µA (!). Thus, the led cannot shine, nor glow.
Thank you

My LED is an Osram LG R 971 with an Normal Current of 20mA, so i have changed the resistor to a value around 300 Ohms.
Then i can bring the LED to shine :-)

Hello Artur,
Thank you for your information and hints.
the RX-TX-switch module works.
Also with control of the mcHF 1W at 29MHz.
The reason was the poor contacting of the GND connection of the TLV2231.

Artur,
many thanks for your help (drawing radiator and so on).
What Do you think - is the PCB-Version 1.6 the last one or do you want to go forward with this project?
Because i ask: If it will be the last version, i´ll finish my Version PCB 1.1 and think about to build a Version 1.6 - but then with the Case from You and of course one of those 500 last SF2142.

Hello Artur,
a question about the difference in the schematic V1.2 to v1.6.
in V1.2 the order (TX) is SAW - TQP3M9009 (PGA103) - SPF5189Z,
in V1.6 SAW - SPF5189Z - PGA103..
Has that a special grind.
Thank you

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?
