You can send your DSL service wirelessly to your home a number of ways.

The best 802.11 units for the money I found are the Senao NL-2611CB3 radios.
They run 200mw and there is also a 400mw version. Also the receivers in these
units are better than most low end radios. I have a 2.5 mile non line of site

If it's line of site, you can probably get away with a good wireless

Mathew,
Did you order just bare crystals to put in some existing channel elements,
or did you send the elements to Bomar and have them compensated with the new
crystals? That may be part of the problem, but usually the lack of
compensation doesn't prevent the crystal from operating- it just
I ordered just the xtals from them. One the UHF version, the crystals that I
had tuned them up are at 434.850, was neither high or low side injection. The

Could it be that far off.

Ok, gonna sound stupid here. The xtal that originally came with the unit was
set for normal frequency range. Does everything have to be redone when you go
with a high side xtal? At this point it will not receive even with a 5 watt ht
next to it, aside the 0 dBm my service monitor gives it.
Yes, you must re-tune the oscillator by the book (LBI, actually) when you
change frequencies.
One of the easiest ways to check for oscillation and adjust the channel
frequency is to set your service monitor to receive the local oscillator
frequency. Place the monitor's pickup antenna close to
Yes, it is a sensitive adjustment. How can an LO crystal not be either high
or low side injection? When you order a receive crystal for a Mastr II or
Exec II radio, you must state whether it will be used for high or low side
injection.
