 >Hi: From time to time I get information from www.sv1afn.com regarding 
his many interesting devices, including for time-nuts: GPS antenna 
splitters, GPSDO blocks, 10 MHZ filters and isolated output distribution

Hi Don,
I would like to have a Oscar100 rtx completely timenutted, including the 
rtx/sdr.

Just acquired a couple of Makis(SV1AFN)'s "triplexers" to send to the 
Hristiyan's SGLabs transverter( SG Laboratory Ltd. (sg-lab.com) 
<https://www.sg-lab.com/TR2300/tr2300.html>, very good) 10MHz from 
GPSDO, 12VDC and 432MHz uplink for Oscar100 with a single coax.

Another one, Jan (hamparts.shop <https://hamparts.shop/>) very 
reasonable prices. I used his parts to have a LNB fed with single coax 
downlink with power supply, 10MHz uplink and Oscar 100 rx downlink.

Radio(FT-857D) is still to be timenutted, using a PLL from DF9NP (27MHz 
PLL for LNB , 10MHz Clock Buffer Verteiler , etc. (df9np.de) 
<http://www.df9np.de/page4.html> another timenut related guy with nice 
stuff).

Latest item (still in transit), the new version of Hans's ProgRock 
version 2, to build a low cost GPSDO (adding QLG-2, no oven):

ProgRock2 triple programmable crystal (qrp-labs.com) 
<https://qrp-labs.com/progrock2.html>

But take a peek at the QCX mini too...you will be amazed about the 
technical solutions squeezed in such a small case at that price.

Just a satisfied customer, no relationship of course. All of them are 
*very* available answering questions about their products and a 
demonstration of commitment to many hobbyists.
