1. [TenTec] Logging programs (score: 1)
Author: G3JAG <G3JAG@patents.freeserve.co.uk>

I use an obsolete beta test version of Hyperlog under Win 98SE on a 200 mHz Pentium. It sees the Omni-V.9 as an IC761. It also sees the KPC-4 TNC.. No problem apart from the fact it is an obsolete pa

2. [TenTec] INRAD filters (score: 1)

Date: Fri May 23 20:17:24 2003
My Omni-V has had only INRAD filters in it for several years now.. Never had a problem with them, ringing or otherwise. Never thought of swapping them out for the original TT filters But I do prefer

Author: G3JAG@patents.freeserve.co.uk (G3JAG)
Date: Fri Feb 7 16:08:06 2003
It seems that key clicks from FT1K rigs are well-known. I understand that there is a fix (see the W8JI website). TenTec keying is famous for being smooth and click-free and I never had any complaints

RE:- X2404P Serial Eeprom in Omni V (Anthony Bowyer NT4X) I have been using one of the X24C04 eeproms in my TT 253 auto-ATU for some time now. I got my first replacement X2404P from TT, but then I bo

I have been using a 253 for years now to feed a 40m inverted V dipole with 400w of RF, via 20 feet of coax to a Centaur balun followed by 50-60 feet of ladderline. I work all bands 80-10m with this s

A new (to me) problem just showed up. On 30m, even into a dummy load, the overdrive lamp flickers and the RF output is a tad down (just a tad from my usual 400) If I increase the drive from the Omni-

I have an old K2 and an even older Omni-V.9. Yes, I plan to have an ORION when I win the Lotto and that stupid stupid stupid Star Wars HAARP project is turned off so the ionosphere returns to normal.

With the US dollar crashing downwards every day it looked like a good time to spend the kids' inheritance and come over to collect an Orion, maybe at Dayton. But if (when) BPL arrives here, ham radio

I still run my Omni-V.9 and I admit to having put a heap if INRAD filters in there. Yes they work fine. But, and its a big BUT, after an awful lot of use on the LF bands, there is little point in spe

The product detector mod I mentioned is applicable to the Omni-V and Omni-VI. I have no idea if it might be relevant to any other TT radio., probably not at least for most folk. Product detector perf

Date: Fri, 17 Sep 2004 18:50:29 +0100
The original RS232 interface is difficult if not impossible to use. There is no provision for handshaking and accordingly PC software (MAC or whatever) has no way of stopping the Omni sending data. I

My 9420 sits under the bench on a couple of wooden rails, just clear of the carpet, in a very confined space. I do not have any added provision for cooling. I have never burnt my feet on it, and the

I notice that if my Omni-V.9 has been on for any length of time, the gain seems to fall off. The is especially noticeable on the upper HF bands and I have to turn the RF gain way up. This is probably

Its heavy and tends to knock lumps out of your shins, but it never blows away in a storm ..... As I get ready to try to disconnect and drag the 9420 out from under the bench I've been looking at the

For years now I have used a pair of ancient Heathkit 4-way coax switches back-to-back. I did retro-fit them with C connectors but I need not have bothered - the isolation between outlets is not all t

Looks like there is more choice than I thought, but the one thing to avoid is firing RF into another rig instead of an antenna. My back to back Heathkit switches do this for me; the one leading to th

The eight transistors are matched. Swapping just one or two out for unmatched replacements could spell trouble. A note I added to figure 4-6 of my Herc manual says set the bias for an idling current

The thing I forgot to mention is that the 253 uses an 8 pin DIL non-volatile ram chip to store the settings. The same chip is used in the Omni-V and maybe in the Omni-VI. That chip has a finite life
