That is exactly how the Drake SP75 speech processor works - Hank K7HP You connect your microphone audio to a little AM or DSB generator, working at some frequency such as 455 kHz. Then you compress o
Just checked my Centurion circa Feb of 2005 and it is exactly the same as Bob's - 150 ma idle while QSK relays are still in . With the Orion even at 100 percent CW QSK DELAY the meter barely damps ou
Looking at Gary's schematic attachment , it looks to me like the output network is a PI-L and the padders are at the "midpoint" rather than at the 50 ohm point. Dunno ham designs what TT designs a PI
Bob - I think your thought about 2nd harmonic may be a very significant factor. I know that in my original Orion 565 I was trying to do a AF freq response watching the RF amplitiude on a meter - Thin
Go to the SONY website and prowl around to service parts and you should find a listing. I have bought a couple replacement pairs for my SONY MDR-V6. To get in the vicinity - the box for mine was mark
Oh , might as well try an "Orion salute" = Master reset - or the whole shebang - maybe its little brain got scrambled. Hank K7HP I run FSK through my DigiKeyer a lot, and have not seen this offset. N
Another lone voice - I also really like my OII - but sure wish both receivers were on same freq when both are using same vfo - not some 5 to 6 hz apart. 73 de Hank K7HP -- Original Message -- From: "
Carl and others - I have never encontered a condition with both rx on same freq, not to say it could not happen if both were general coverage . But I think it has to do with mathematical resolution l
I have talked to guys who say the O1 was closer and in fact my 565 seemed to be more like 3 hz apart - I have had two 566 O's in the shack and they were both off 5 plus fractional hz. I never worked
DE K7HP I have never encontered a condition with both rx on same freq, not to say it could not happen if both were general coverage . But I think it has to do with mathematical resolution limits in t
Very well clarifies it - but in the original Orion with some early 1.3xxx versions at least - even when it said the hardware blanker (off:H) to OFF it still was on !!!!! Where I live in a bed of high
Anyone recognize the "HHF 16" that TT uses for their pushpull PA driver in the OII 566 . I cannot seem to get any hits Googling. Forgot to look and see if they were marked the same as what the schema
For anyone interested - the part is a Mitsubishi RD16HHF1 - explains why I could not google it as HHF16 - Hank K7HP Anyone recognize the "HHF 16" that TT uses for their pushpull PA driver in the OII
Duane / Fotis - Turns out I have been looking at the 566 PA module for some different reasons than getting more power - but - the output devices are pushpull 2SC2290 bipolars - the driver for that st
I had not thought about the move of the notch between ver 1.3XXXX and the ver 2.0X or OII - but I know I have seldom seen any use for it on CW with 10 hz tuning steps for the notch center freq. I wor
Have you tried switching the load to ANT 2 ? Is the power supply current changing as you raise the power ???? Hank K7HP yes, thanks. Keying loops are off and transmitter is ON. I do have the rig goin
Dunno how the link disappeared - it was on my "sent" . http://www.users.qwest.net/~pfizenmayer/ Here is a link to a pretty complete SPICE analysis of the A9 board - its the bottom line in the table.
Ron - a word on how the 22.7 multiplier comes about - It is not just voltage - Illcap says going from 35 volts to 6 volts approximately a 2X multiplier is valid for voltage . The rest of the multipli
The TenTec capacitors in my O 565 and O 566 were NOT Chinese made - nor were any others of which I am aware (about 5 other Orions) - they were made by Illinois Capacitor - the capacitors were of good
