Not sure what the power 'should be', but a transmitter with a pa rated for 100 watts pep should give about 25 watts carrier when the ptt is pressed. 25 watts of carrier plus 100% modulation would be
I just got my Orion 565AT back on line after the DSP board serial port died on me. Turns out the chip capacitors that produce the negative volts had gone bad. Ten-Tec kindly fixed the board I had shi
I use a variety of software but mostly 2.062a and the latest beta. There are something's in the beta I really like and I'm sure the continued development will only improve on these whilst hopefully f
Some time back I recall seeing messages to the effect that a new version of the Orion II firmware was going to be released and indeed was released. Since then I have heard little in the way of feedba
Late last year the serial port on my Orion failed. The DSP module was returned to Ten-Tec who replaced the 4 ceramic 1uF capacitors. I replaced the board and it worked well. Until today. I have been
Thanks, It seems to be working again now. Or at least I was eventually able to load code into it and it seems okay. The symptoms were that the firmware loader was telling me it could not find the rig
After being able to load software into the radio again, not sure if it was PC serial port cable or connectors but it's okay now, I'm now seeing that at almost every power cycle the radio does a maste
There's a battery? Who'd have thought. I know it says battery failure when doing a RAM clear but had assumed (ha) it was just a way of saying that the process had taken place. Maybe standard device t
Okay, now I'm really confused! I'm looking at the V2 sweep mod document and have my 565AT in bits in front of me. Cannot for the life of me identify a battery anywhere on either the document or the h
DSP/CPU board, U501, Yellow oblong, ST device marked C996160215, M4T28-BR12SH1, Timekeeper Snaphat Lithium Battery. Looks like it's plugged in to a 16 pin DIL holder designed to be mounted SMD style.
And some more, The schematic I have calls out an M48T35AV, a combined 256K SRAM real time clock, power fail control circuit and battery. Fitted to my radio is an M4T28, a 48mAh battery and crystal. H
Spec says 2.8 volts nominal. Mine says 0.8 volts! Whaddya think? --Original Message-- From: tentec-bounces@contesting.com [mailto:tentec-bounces@contesting.com] On Behalf Of Martin Sole Sent: 16 Octo
Indeed, but oh so defeatist, hi hi! The thrill of the chase an all. An email or phone call to Tentec could save a lot of investigation. Carl Moreschi N4PY 121 Little Bell Drive Hays, NC 28635 www.n4p
Got it and thanks, boy that wiki takes some digging through. Looks like I need to get one on order, maybe the 120mAh. The one fitted is 48mAh. As a quick fix I think I can fit a coin cell holder with
Thanks for the information Ken, I have no real issues working on smd stuff, I have most of the right sort of tools and can do all but the really scary hundred legged devices. So far as I know I haven
Thanks Rick, Looks like I'm about a year late, oh well, now I know. Will try without the crystal to see what happens. BTW. Just finished a Z10000 buffer amp and installed it using your notes. Great j
Snaphat battery and crystal removed. Coin cell holder temporarily lashed up and fitted with CR2032 lithium battery. No crystal fitted. After initial resets radio appears to function normally and afte
This problem interests me. I note that Ten Tec has a good reputation for fixing older gear where it can but it seems there are a few older Ten Tec radios that have problem parts made of unobtanium. J
Have you been through the various reset sequences, master reset, RAM clear reset? Okay, well this thing is acting very weird. I did some more testing tonight and here's a quick summary. - The main re
So I thought I might have a play in the test this morning. Well first I need to hook the Orion up to the pc. I have a keying interface that has 2 transistors arranged to pull down the PTT and FSK lin
