Hello to all,

I connected the unit to a 11m of H-155 cable(assumed 4.79dB loss "worst 
case" at 1.5GHz), thrown the GPS antenna on the balcony horizontally and 
this is what I got:

Seems to work (? I understand this from GPS phase and FFOM 0, not sure 
about the hold position status) I have somewhat stable 10MHz output, 
tomorrow I will use a mast for the antenna to get it higher slightly 
above the roof, (vertically this time!).

- I got the software from the seller but complains about some ancient 
OCX stuff don't want to mess with ActiveX anymore, hopefully Lady Heater 
will support it soon.

- Given the attenuation (less than 5 dB) do I really need to change the 
cable for something better?

Leds are Yellow Activity solid, red unnamed blinking fast,  Red 1PPS 
blinks once a second and DC green is solid.

Anything else special to check?

PS: the other clock (qrp-labs) is way behind schedule, but hopefully 
will arrive soon
