FWIW - At Dayton this year - I bought a few feet of stuff from Heil that is nice and flexible - has two twisted conductors in a shield and two more outside the shield. Just says Heil Sound on the out
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
Speaker output on O II is MONO. So a simple dropping resistor in series with the speaker will reduce speaker level if needed - but none of the various combinations are available . In fact I know peop
Now lets see -- 4:30 pm - Eastern time - but is that EST or EDT ?? So 1630 EST to UTC is 2130Z - but if its EDT its 2030Z By same token 5:30 pm becomes either 2130Z or 2230Z . Now my QST says from fi
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
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
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
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
QUOTE ""All-new suite of ORION II-specific roofing filters is arranged in one, single bank to allow user to select the absolute ideal roofing filter for mode, band conditions, and personal preferenc
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
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
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
