MAN, you guys are good !!!!..? Very obvious thing overlooked. HI.? All good now.? I had schematics out last night trying to figure out what components could be bad.? You made my day.? Any of you

Check to insure the MOX button is not pushed in. The MOX button is right under the power switch, easy to push by mistake. 73, Tom K6EU [email protected]> wrote:

I have a 847 that had been working fine until I started tinkering with the DATA IN/OUT jack trying to interface a computer.? Now when I turn power on it is in TX continually and cannot get it out?

Dear Stanley, I good suction desoldering tool will help here to get as much solder off as possible, there are two ways, I find with a broad soldering tip and an iron of around 60-80 watts, flux the

1)? At a bare minimum you need a hot air rework station. 2)? Better is a hot air rework station and a PCB preheater. 3)? Best is what I use which is a automated computer controlled rework station

what is a good procedure for removing the PA from the FTM100 motherboard? I have used solder wick to remove most of the solder but of course it is still attached. I have no special tools for that. Any

Thank you very much for this info, A65BR Oleg. You are rigth, the capacitor is C1280, see attached photo. Thanks, OZ1BXM Lars

HI Lars I could find Q1107 on the schematic diagram, maybe you can find C1200 ? if I see C1200 is around pin 12/13/14 of Q1107 ? Good Luck Sjoerd PA3DOL Sent: donderdag 16 mei 2024 10:49 To:

Hello group, I've replaced the chip Q1107 on the AF-CTRL board, but I lost C1200 (sits near Q1107), and I cannot find a parts list for FT-847. Does anyone know the value of C1200 on the AF-CTRL board?

At this point, the transmit level needs to be 5 Watts (+37 dBm) for driving my current transverter(s). So, just using the normal output, not any taps internal to the rig. -- Cam, W4XXV

Was the plan to use 0db as the drive level, if so the lpf issue won't be a problem because your bypassing the PA [email protected]> wrote:

I should have added? "and other transverters". I also want to make use of 222 MHz as well, requiring the use of 28-31 MHz transmit. So, the question still stands. -- Cam, W4XXV

Cam, why do you want to use a transverter with the FT-847? Is there something deficient with the 2M mode of the Ft-847? If so, seems like it would be far easier to address the problem than to go the

You can easily change the FT847 to TX from 144 to 174 MHz, Also the use version goes from 144 to 148, http://f4cqa.free.fr/modposte/tf847/ft847.htm 73 Andrew Sent: 15 April 2024 18:05 To:

Hello all, I'm trying to research the capabilities of the use of the FT-847 with a transverter, requiring the use of 10 meters. The issue may be the requirement for opening transmit to 32 MHz to get

John, There some magic inside that SL to close the circuit to allow the audio to pass to Tx on the rig. I just cannot figure out what is happening to make it work with the Easy Digi board and the pg
