When something in the power to it totally craps so there is no display at all - its blue - hope to have that issue resolved later today - TT says probably the -20.5 volts on the power dist board. Han
So far its the 5 volt totem pole regulator on the 81936 power dist board now that I have it open - the 20.5 neg supply portion is still fine . Have not figured out where the smoke escaped to yet. Rat
FWIW - The OII has a separate amplifier for headphone independent of the speaker amp. OI did not have this. The headphone amp appears to be in the order of 3 ohms output impedance as close as I can m
Try checking where you have the taps set under FILTER . I find that at other than even spacings of 20 - the DSP will start oscillating at narrow bandwidths when you vary the BW. It seems ok at taps s

George - There is a trick whick may or may not nelp your firmware dsp blanker (not HW blanker)- I operate mostly cw with 300 hz filter and DSP even narrower and on some noises I find that forcing the
FWIW _ I have had two Orion II in my shack - one stays within 1 to 2 cycles at 15 mhz from cold to hours of contest or normal operation. The other one was abysmal (in relative terms) it moved about 6
While you guys are on the subject - is the CW sidetone adequate with the Heil Proset ? - I have some SONY MDR V6 phones and the cw sidetone is very marginal. Regular RX audio is fine . I only get 60
I would like someone to give me a second check on the CW sidetone on the OII. I have some SONY MDR V6 phones and the cw sidetone is very marginal. Regular RX audio is fine .The SSB monitor level is f
Beats me why TT offers us nothing for EXTRA (beyond that sold with the rig as standard) filters and in fact tells us to take them out - I vote - NO WEASEL - PS - Since my O II appears to be a keeper
A "trick" under uncrowded band conditions that sometimes makes the DSP NB very effective is to force the main rx roofing filters to 6 or 15 Khz - then try the DSP NB. I stumbled into this one evening

Have a 219 250 hz filter left which is surplus to my needs. Its from my 565 Orion I traded in recently . Asking $65 and I ship. Can do paypal or money order. Hank K7HP _______________________________
RE OII VFO A 14254 TX and RX VFO B 13974 SUB RX ONLY Works fine on mine . I also checked with another rx to be sure it was tx on 14254 and not 13974. 73 Hank K7HP ____________________________________
FWIW - A much higher voltage breakdown generally indicates a higher resistivity substrate is used to start with and so the "ON" resistance might be higher than a lower breakdown device - for this app

I should preface this by I don't know if the Omni VII sweep is different than the OII sweep - but here is my opinion about the current OII sweep. Maybe its just different strokes for different folks
The OII has an entirely separate headphone amplifier IC from the speaker amplifier IC. The master AF gain affects both speaker and headphones - but the basic levels are settable in firmware . Both IC
