We could add any of the dozens of LO frequencies that have been used in the past 20+ years, but if they aren't used, why add them?
Easy to add KA high band if there are FTA services.

At this point, the smarts and beauty within are more important than winning a MIss STB Contest. Don't get me wrong. The GUI is very functionable and we have reworked the layout, text and functions, but I have never been a fan of the default graphics and design.

Okay, subject to confirmation, let's see if I got this right.
In a normal LNB, the LO is 10750.
Being lower than the incoming signal, this is called low-side injection.
The incoming range is 11700 - 12200, MINUS the LO Of 10750 equal 950 - 1450mhz.
These are the vertical transponders in a stacked LNB.
rcvFreq....LO.......receiver tunes
11700 - 10750 = _950
12200 - 10750 = 1450
But, having the two local oscillators too close in frequency, leads to all sorts of bad things.
So, having the second oscillator set for high-side injection, you'd get this:
The incoming range is 11700 - 12200, MINUS the LO Of 13850 equal 2150 - 1650mhz.
rcvFreq....LO.......receiver tunes
11700 - 13850 = -2150
12200 - 13850 = -1650
This is where the horizontal transponders appear on your cable between LNB and receiver.
Ignore the negative sign on the frequency. It's meaningless.
So, the Vertical transponders occupy the range 950-1450 on your cable, and Horizontal is located in the 1650-2150mhz range, and backwards.
Now, any simple splitter can feed multiple receivers, and each receiver can select vertical or horizontal, without interfering with any other receiver.
The stacked 10750/13850 is no problem and will be implemented. Thank you for the parameters!

A Standard type LNB is a single LO. An Universal type LNB is a dual LO with a voltage controlled polarity and a 22KHz switch at a defined frequency switch point. A Stacked type LNB is a dual LO with fixed voltage and polarity defined frequency range.kodaz said:if i select standard LNB, is the 10750.13850 option still available?

We will be releasing the Owner Manual at the time of the product release. Sorry, no prerelease.rzg00 said:Is there an alpha (or better) version of the receiver manual yet
No as this is a USALS calculation limitation.cracklincrotch said:Does the MicroHD allow more than 40 degrees of travel on each side of a true south satellite using USALS?
My DG2100 covers at least 58 degrees (to 15W) east of due south and 66 degrees (to 121W) west of due south when used with Coolsat 7000 and USALS. I believe its physical movement specs are +/- 70 degrees. USALS is best only to find the first satellite or two anyway. I find it's best to use DiSEqC 1.2 to precisely aim for each satellite, maybe since I'm closer to the edge of many footprints with little leeway for error....50 degrees of travel east and west of true south, for 100 degrees total, would be cool, if possible.
