Enzo,
I had the same problem , loose of rx when transmitting.
The culprit, in my situation, was the DC injector ; i used the same model as on your picture.
So i changed this DC injector with another model and bingo....continuous RX.

Feed holder is made of a plumbing pvc tube + a heated muff pvc.
Lnb is a modified Gosat + tcxo.
What do you mean by 'original rill feed' ?

Hello to the group,
An old vintage primefocus dish, made by Philco USA and used by the NATO microwave network, is now in the garden.
Diameter 190cm, depth 30cm, so f/D 0.39.
Results with the DJ0ABR linux webserver show an average noise transponder of 5.1dB.
Technical comments on the results with this dish and its usage on 2.4 and 10GHz are really welcome .
Some infos about the ACE network are also appreciated.

Hi Robert,
Extracted from the Amsat Converter Doc : "Attention: The reference clock is only applied to the WB-LNB connection."
So I do not understand further more....
So do we need to have the NB AND WB together connected to the LNB ? I was using only the NB part.

hi, dj0abr
Hello Kurt,
Tnx for the comments.
The LNB used a tcxo 25Mhz clock ; so I modified the jumper position as the doc recommendations ; 10A ; so jumper on horizontal position....helas !..no signal...
Any ideas ?
tnx

Again thank you

Hello Robert,
i use a lnb with an internal clock modified by tcxo ;
the previous amsat downconverter works like a charm !

Hello to the group,
I plan to use the two types ( OCXO /GPS) of Amsat downconverters to listen to the NB transponder in a first step ;
for this, the LNB signal is injected in the upper left F connector and the 144 Mhz signal comes from the upper right bnc connector.
The jumpers voltage are in position 'by default' and the 4 leds on the right side of the pcb are illuminated except the 3rd one (green) which is blinking.
The output frequency selection is on 6 which corresponds to 144.550 Mhz.There is hiss but no audio.
What am i doing wrong ?

Hello Thomas HB9SKA
Tks for reply !
In fact, I use a PE1CMO transverter which needs a PTT (grounding) signal.
Normally I use an ft100 which has this signal on the ACC connector (idem for FT736).
But TS811 has none....that is the story

Hello to the group !
Is there any body using the Kenwood TS711/811 for driving a transverter ? if so, would you please supply the detailed schematics for PTT output.
73 tnx

Hello Neil,
I dont hear is0grb anymore too...so perhaps it was a testing phase.
Notice for .625 ; any problem with .645 ?
Tks

Hello,
Following these positive and excellent tests using the vara modem, I will put on the air the BPQ32 switch in the next few days on 10.789.625 ; access via the Vara modem in a first step.
A question : should it be interessant and possible to use the 'old' PB-PG FTL0 protocol used on the first microsats ?
