HI Bruce quietly use two preamps through MENU 29 and 30 UHF-AMP and VHF-AMP power supply The FT847 is not full duplex, so it will only feed one at a time and the current, at least with my LNAs, have

*FT847 QRP or QRPp for TRANSVERTER* HI I have to use a low power output, *with no possibility of high power error* , to drive an external transverter for 13 and 23cm or QO100 upconverter. I would not

But does the 847 not supply the required voltage?? It is not from the pre-amps.? The radio powers the pre-amps. Grim? - ZL3TV

Hello. Sorry, but I don't understand why you may be looking for trouble connecting the DC supply of the AR's LNA's to the FT-847. I can tell you that after 6 months of working on a faulty FT 847,

The preamps I was looking at were the 160 Watt thru power premaps (MSP144VDG-160 and MSP432VDG-160). These require 200mA each during RX. After further investigation I thought the UHF port was broken

Morning Bruce I just looked at the website for Advanced Receiver Research, and they say all their receivers require 25ma. Well within the parameters for the 847. Even the military receivers were at

I just acquired a used FT-847 and plan to use it for VHF/UHF work including getting into satellites. I have one question. I plan to get preamps and am looking at 2M and 75cm mast preamps from Advanced

Does it matter which mode the rig is in?

Talk to Geoff at Castle Electronics. I think he can replace the cpu on your board. http://www.hamradiosales.co.uk/CASTLE-1A.htm?LMCL=FREueB&LMCL=UAj68Z /Nils SM7DVO

Hi FT847 users I have a question: I have a FT847 that will transmit immediately when I turn ON the TRX not always but nearly always Now and then the TRX works fine for some time , then suddenly

Hi Leighton, No I haven't changed the battery as the frequency and other settings on the radio do hold after restart. Its the internal microprocessor values that doesn't hold where you enter into the

Hi Gilt, one question - have you replaced the internal coin cell battery ?. Leighton. GW3FSP.

I have a fantastic rig but the microprocessor is not working well means cant hold the settings and cannot return to factory settings all values are reset after power off and switched on later. wonder

I looked at Mouser.com and DigiKey.com both. They had them. 73 -- 73 Douglas Richards VE3FFR ve3ffr@...

I bought 10 on ebay and paid all 10 pieces together for only $ 5 and shipping included: they were fine. On Ebay you can find them at very low prices! Just search MINI DIN via google or via ebay and

Yaesu uses a 5 pin mini DIN plug on the FT-847. This plug is used as a connector for a cable to key a linear amplifier. Actually they use the same connector for HF, VHF, and UHF amps. I had a

I double checked and its the same for my 8900 and it works fine so I'm confused. I don't know if it's a delay issue and if someone knows what that number should be I would appreciate if you could

Morning John I just went to Tigertronics website, and they have cables and wiring instructions for both the Data and Packet ports. Hope this helps. Douglas

I've thought of using the mic input also. I don't know if my 847 is an early unit or not. I forget now but the serial number has to be G or later if I remember correctly. Doesn't matter because my

My 847 is an early model and I can’t use most digital for it. I didn’t find out in time to send it in for the update. However the only way I ever got packet to work is through the microphone
