- No. I disagree. It is a code. Its plural is 73. Here is another word, SHEEP. Have
- yos seen many sheeps recently? Back to the point, 73 is not English. You would not

- Sure, some folks have operated mobile above 1300 MHz. I think it would be the

- Uh, yeah. Read my first paragraph again. My emphasis was indeed on
- mobile activity. Wasn't that clear?

-
- These are (more or less) line-of-sight paths in the upper UHF range
- (L- and S-band) with a predictable path loss.
-
- However, if you operate well below line-of-sight you had to allow for a
- huge fade margin to fill out the shadows, since diffraction doesn't
- bend the signal around corners and roofs very much and you have to rely
- on reflections from buildings on the opposite side of the street.
- Even the free space path loss increases rapidly with frequency (or
- actually the capture area for an omindrectional antenna is proportional
- to the square of the wavelength), so you have a bad initial situation
- before you even start to concider difraction or reflection losses.
-
- If you want similar omnidirectional (horisontal) coverage as with
- repeaters in lower bands, you need much more ERP. The radation pattern
- at the repeater site can be flattened to a few degrees, the mobile radiation
- pattern to maybe 10-30 degrees and the portable to 40-90 degrees to get some
- antenna gain. Beyond this, you have to use adaptive phased arrays and
- have to forget about round table operation.

-
- Yes, but the cell size is much smaller than in amateur repeaters.
-
- The cell size in cellular phone systems (NMT-900 and GSM (900 MHz))
- in urban areas are usually a few hundred meters. Outside urban areas
- there are short towers every few kilometers along main roads with highly
- directional antennas aimed along the road. This way you will get
- high ERP on the road but no coverage one kilometer off the road.
-
- To use smaller "cell" sizes in amateur systems, you need
-
- - a high amateur density to (financially) support a large number
- of repeaters
- - to a number of repeater sites
- - large number of _cooperative_ amateurs to build repeater networks
- for any usable coverage.
-
- The last requirement might be the hardest part :-)

- This makes much more sense.
