WH> HR> WRONG again, spec is 100m per segment. WH>Actually, this depends on type of cable... Well... NO, While in the real world, you wouldn't try to run it on cheapie "silver satin" phone cord...The IEEE specification for 10BaseT defines a maximum segment length of 100 meters irrespective of cable type. Now, elsewhere in the spec you can find what cable types are acceptable for 10BaseT, but the maximum (or .6m minimum for that matter) segment length does not change. And in TODAYS real world, CAT5 is cheap enough to be considered THE standard. HTR --- . OLX 2.2 .

How much distance was between the area where the LAN was and the actual transmitter itself ?! I can't imagine a tech not keeping those two things as FAR away from each other as possible, by at least housing the xmtr in an RF tight box perhaps on the roof - near the antenna so the transmission line (coax) could be as short as possible ?!? Of course, if you're talking about a studio that uses a satellite network to broadcast and the only xmtr is the uplink at the giga- hertz level instead of a groundwave array, then I can understand why there is no problem with RFI. Also, the frequencies that TV are at is quite a bit higher than that of Shortwave and Amateur HF stations (1.8 - 29 Mc). Plus, I imagine that the 'mode' (FM vs SSB/AM) has a lot to do with S:N ratio. I have a UPS here that puts an S-8 noise signal on my shortwave receiver (both the Yaesu AND the DX-380) in ALL bands. It's not some cheap UPS either, it's an Exide 600va 'top-o-the-line' that cost me about $1/VA (just to explain how susceptable the lower freqs are to manmade RFI (QRM)). It's not until I get at LEAST a block (300 yrds) away from the house that the noise falls into the static level. I figured since the NIC actually has an oscillator and is basically an RF tranceiver (unless "T" is much different than "2"), they would be a VERY harmonic 'rich' source...

We have a Tally5 on Novell Netware 3.12 and Win 3.1. Whenever the largest of the voucher is opened it gives out of memory error. The node is P-60/32 MB RAM/260 MB HDD. The swap file size is 76 MB since the dealer recommended it more than 20 MB & maximum possible. The server is a Pentium-100 with 32 MB RAM, 1 GB SCSI on PCI-SCSI NCR. I even downloaded the entire software on local harddisk with the lock placed on the local machine's parallel port but it would still give me the same problem. Anyone having faced the above problem & found a solution would be ready to help I am sure so thanks in advance, God Bless..... Reply to me at fortune@lwbbs.net Regards and thanks, Kshitij Kotak.

Good idea Will, and I had originally planned on a BNC network, but unfortunately the NICs that the seller advertised as "2/T" - showed up as "T" units. Since the price was pretty good ($9 for 4 SMC NICs, $5 for 2 3COM NICs), I decided I'd give them a try. The NICs are set up to allow connection to STP RJ-45's, and I figured if the hub was going to be too pricey for an STP model - I'd just put it in an RF-tight 'box' and run a drain wire from the shell of the RJ-45's to a common ground inside, after running the cables through grommet (not the dog :) holes/slots in the box.

Huh? I snagged a copy of that a while back, and you had your choices of whether you wanted install from your HD or diskettes, and whether you wanted network support or not, but it was just a straight install as far as I can recall, no compile or anything remotely resembling that. I do recall hearing something about them making source available too, but that doesn't seem to be a required way to get it going as far as I can remember. email: roy.j.tellason%tanstaaf@frackit.com --- * Origin: TANSTAAFL BBS 717-432-0764 (1:270/615)
