4mtr info

Paul Williams All Messages By This Member #168 开云体育 Hi Mickey, ? Can I ask you , is your ft 847 a C2 model if it is, then 4 meters comes as standard. Check your serial number, that’s serial numbers after 9E so that means May 99. ? 73’ Paul ?

Hi Paul. No worries on my name, many people also choose to spell it with an 'e', but I don't. I don't look anything like that famous Mouse... I also have just received my FT-847, my best friend had one that his widow agreed to sell to me after he passed away in July. She had sold it to someone else before I got down there with the money. Anyway, I finally found one, and am currently putting it thru it's paces to see if everything is working OK. I am able to program memories using the FTBasicMMO software just fine now, thanks again for the tip. You will need the software if you choose to program the memories for SAT use, (not REALLY necessary, but it helps a lot!) makes crossband programming a lot easier. I don't have the AZ/EL rotor and antennas necessary yet for satellite use, that is probably the last thing I will work towards this year. I am not sure about the 4M mod, how would I check to see if it is enabled? Is there a setting in the extended menus for that or does it require pulling the covers off?

Micky Corrow All Messages By This Member #169 Hi Paul. My FT-847 does not transmit on 70 MHz. It is a 0M serial, which should place it at November 2000. After looking at a detailed photo that I took this morning with the bottom cover removed, it appears to be un-modded.? I did a bit of digging on the Internet and it looks like Keith G4FUF is the master of this particular mod. From his writeup (??) it does not look really worth it, at least I am not willing to tackle it. If I weigh the risk versus the reward, I don't think there is enough activity here in the NorthEast to justify modding my radio. Then I would need a whole new set of antennas... Micky K1XH
Carey W4TFZ #170 Remember that 4 meters is not legal in the US; where it is a small band available in Europe. The 4 meter band frequencies fall into the same range as some of our original 13 VHF TV channels for over the air broadcasting. Channels 2-4 are 54 MHz to 72MHz and Channels 5-6 are 76MHz to 88 MHz according to frequency allocation chart. I'm pretty sure that any US models would not have that option.? Carey W4TFZ
Paul Williams All Messages By This Member #171 开云体育 Hi Micky ? Ahh! I can see that there is a difference between the U.S. and the U.K model. Carey W4TFZ pointed out there is no 4mtr band allocation in the U.S. Thanks for the heads up Carey ? ? Hey Micky there is only so much aluminium(antennas) a radio tower can hold! ? ? Paul GW4ZYG ?

Andy Bosworth All Messages By This Member #172 For what it is worth. The 70Mhz enabled radios (C2) do not work well without modification.? Approx 12 watts output for 15 amperes current draw, and a very deaf receiver. Add spectral purity on the output signal that includes a signal at 48Mhz only about 4dB down.? The problems appear to be the wrong value of components fiited in filters on the TX side, and the requirement for a pre-amp make it an expensive way to get on 4. A friend of mine weighed it all up, and decided on a transverter from 10 metres, which works considerably better, and easier to implement.
