Yaesu Ft847 No Power On Sideband
The FT -847 is carefully designed to allow the or lead components only. Knowledgeable operator to make nearly all ad- While we believe the technical information in justments required for various station conditions, this manual is correct, Yaesu assumes no liabili. Your FT-847's 'talk power' is enhanced by the built-in RF clipping-type Speech Processor which increases average SSB output by approximately 6 dB. And the transmitted IF passband frequency may be adjusted via Menu, to match or enhance the frequency characteristics of your voice pattern. Best Answer: how are you measuring output power, you say it is not transmitting. In SSB mode there should be no output power in the absense of modulation. Put in CW mode to tune. You need to be connected to a resonate antenna or a dummy load to tune. To trouble shoot remove the 12BY7 tube, use a ham receiver and listen for the oscillator output on channel when keying. Verify the VFO is working.
I have installed the TX & RX Collins SSB filters and the CW Narrow Collins. I’ve also converted the Icom EX-1514 External Vox to compliment the unit. Now to the best!!I’ve read about and have always worried about the power switch! Though my power switch has showed no problem as of yet(maybe because of the lack of use) I ran across a idea that I couldn’t resist and it has turned out terrific.
My power switch now only conducts 30ma of amperage-Interested!!-I was!!!While at Radio Shack I noticed a small 12VDC relay @ 10 AMPS Contacts that looked small enough to mount behind the front panel!! Still interested? I was!So for $3.99 I took a chance that my memory was still active. The following photos shows how perfect this relay fits. It’s as though it was made in heaven!
The wiring is pretty much straight forward so you shouldn’t have any problem with it, especially with the photos. Basically, the original green and white wires to the circuit board plug(on the front panel) were cut and re-routed to the relay switched contacts. Then I tapped 12VDC at the rear power connector BEFORE the relay switched + 12vdc(activated by the front panel power switch) and spliced that to one the front panel plug leads that was cut(Orange wire).Then the other lead of this front panel plug was connected to one of the NEW relays coil contacts(Red wire/White tracer).The other lead to the NEW relay’s coil was connected to ground(Black wire). As shown in the photos, the relay was mounted with double sided tape next to to cooling(unbelievable perfect fit!) fan and high enough to clear the phone plug circuit board when the front panel is tilted back into place. Now the power switch only conducts the voltage and current to activated the NEW relays coil!
Oh, life is GOOD!Use this information any way you please so other users can quit dreading the Power Switch gremlin from visiting their shack’s.Cheers and Beers-The Radio Shack Number for the relay is RS-275-0248A.
Yaesu Ft 847 For Sale
My Yaesu FT847 losing power on HF but still around 50watts on VHF? After some basic checks (only check) open cover do some troubleshooting - supplies, fuses, plugs, burnt smells, all seems ok. I was thinking to work out the PA Units Adjustments before that im looking for anyone who knows this symtomsJust so you know i was very active on ft8 mode with the wsjt-x before this happen. Power seems unstable that time, but i wasn't really aware that is some abnormal behaviour so i ignore until i lost the power.Any help would greatRegardsDave, 73's.
Fallout 4 institute mods. I'd love to collaborate with some creatives and developers to make this happen. Indeed, it appears that although the G3 Synths emerge after creation with knowledge of speech and whatever skills are imparted during that process, the G3 Synths often require remedial training. .Generation 4 Synths: While the Generation 3 (G3) Synths are the peak of this technology, they are flawed because their programming can be corrupted, and they can stop obeying orders or think that they are sentient (rather than malfunctioning). It is possible that because the Synth Component keeping them under control is bio-tech, that it degrades over time.
