    Close proximity to objects will change the SWR so you will get differing results in different locations. You should be able to tune it by adjusting the feed point. Kind regards, Phil

    Ok roger on the coax, I can improve on that, but would still like a better swr. Might try a choke at 5 or 10M. Pee Dee

    Ok thanks. I did that, replaced top two sections with bamboo cane, but still swr of 2. So will probably play about with coax length, maybe a choke at 10M. Pee Dee

    Sounds like switching transients in the power supply are not being filtered out and are therefore superimposed on the "pure DC" output. Filtering should be the manufacturer's concern if it's a new power supply (still under warranty). If he's not willing to fix it, it becomes your problem to repair or get a new supply that you can try before you buy.

    SWR is the least of your worries. Even if the Slim-Jim had a perfect 50 ohm feedpoint impedance, 15m of RG174 coax on 2m will dissipate 70% of your power as heat in the coax. 10 watts out of the 2m rig becomes 3 watts delivered to the antenna. RG-213 would more than double your radiated power. LMR400 would be even better.

    I found that the tone/hum is only present when the rig connected to switched power supply. It is not present with linear power supply or battery. Maybe someone could explain this....

    Its probably the carbon in the fibreglass (I guess) making the mast partially conductive. Black plastic pipe has this problem too. See if you can remove a couple of top sections and replace it with wood...

    Pee Dee started a thread swr problems in Antennas
    Hi I have made a 2 meter slim jim from ladder line, and it works well hanging from the upstairs ceiling in the landing. Can work all the Poole Radio Society members in the area with 10 watts on the weekly net, but I decided to see what happens if I raised it up outside, So I bought a 10M roach pole, and 15M of RG174 coax, attached it to the top of the pole, raised it up the full height, connected the coax to my handie via psu, but no matter where I connect the coax to the Slim can I get a swr below 2, I guess that aint bad, but I was getting 1-1.3 on the landing. I wonder if the long length of the coax is affecting this? Any ideas please Thanks Pee Dee

    Pee Dee started a thread keyer in Accessories
    Hi all Can someone help with this? My CM Howes, 80's vintage, keyer is playing up. Dots coming out as dashes and dashes dragging out to make long ones. I can only assume it is rf getting in. I have already changed the keyer box from plastic to aluminium, and replaced the lead from keyer to TX with coax. That cured it for a while, but now it's started playing up again. Would the solution be ferrites on the leads? Advice appreciated. Pee Dee

    Hi everyone, This kit was previously modified for use with DDS: http://prekladatelia.info/chinesekit.jpg I used ceramic resonator as Y2, tuned by a series variable capacitor around 130pF. It tunes from 3.5MHz well into the phone segment of the band. However, when I soldered in the rx part (using an LC bandpass instead of Y1), it makes a continuous sound as seen in this video: http://prekladatelia.info/vacuum.3gp

    they should not be sending you a new product that needs updates...it should have all the current stuff on it when you get it. If they come up with updates that can be loaded onto a product at a later date, so be it... but new ones should go out up to date. If a dealer sold you an older model that did not have the updates on it, that is on the dealer and should be updated by the dealer at this cost, or the dealer should have told you so up front and given you a discount if he could not update it, then you could choose to take it or get an updated one somewhere else...IMO.

    When I buy a product, especially an expensive one I never, ever install any firmware upgrade until the manufacturer or distributor tells me to. I buy the product based on what it does, and what I need it for. If it functions, then I keep it. If. to it goes up. firmware upgrades are for improvements or fixes for bugs. I have loads of radios here that I hire out and most are on their original firmware, when loads of updates have been and gone. What are the problems the radio had that needed fixing? If my new expensive product was flawed, then it should have gone back.

    Yes..... I'm trying really hard to hold my patience with this nonsense, If knew this would happen I would have even paid to have updates done before they shipped this radio.... I like this radio so far after learning some basic function on the FT991A, but we will see had pans out.... cause I may not ever bye another Yaesu again, I don't like being screwed over after paying this much $$$, nobody should have to deal with this kind issue. Now after reading another post, a fellow said he waited several "Months" to rectify the problem! Think I'll will phone dealer, may have ship back (my expense), not sure warrantee even covers this & if it cost my more big $$$, Yaesu will be on my sh^! list !

    I find it very hard not to expect dealers to ship products with the absolutely latest stable firmware in them. It seems mad that you need to take a perfectly good radio and then risk wrecking it yourself. I would find receiving a brand new expensive radio and then having to do this an example of a dealer or manufacturer simply asking for trouble. Clearly, they are lucky in that their customers have a higher than average chance of completing firmware and software upgrades successfully. It's not good customer care to ship a radio and say, have a go updating the old stick radio we shipped you yourself.

    Did exact same on my new FT991A, wish I seen this post before trying to upload the new firmware..... It seemed to install first main firmware, but when I went to install the TFT firmware...... say to plug usb, no external power, the push & hold F-M-list +Band + Mode + Power at same time, this is suppose to power up the Computer screen panel for installation. It didn't do anything! Not sure if I damaged the radio or not. Not sure what to do now ... should have left it alone, seems like the radio was working fine, used it on FM, C4FM worked, I really like this radio ... could not get WiresX going cause I figured it needed update ... oh boy... but I just had to try updates hhmm ... KG5HFO did you get you issues resolved, if so, any advice or is I'm I going to have spend more $$ to get fixed? KG5HFO I'm feeling your pain & frustration ... after retrying several times Thanks for any advice VE7OPL

    Well, in this case, reading the manual did not help very much! I have been a ham a long time and have had many rigs. I think my interpretation of the manual was reasonable, although I can see another way to interpret it. Anyway, if any of you FT-857D owners out there start experiencing RF gain drop out, my experience may help you. The problem had me frustrated for weeks, and even Yaesu suggested I send the radio in for service after I described the problem and even sent them a video of the symptoms. The problem was a little tough to diagnose. I wish I had figured out the solution before spending the money to ship it to Yaesu.

    As long as you are transmitting within the conditions of your licence i.e on an approved frequency and less than 10w erp, you are perfectly legal. You are not restricted to just speaking with other amateurs in the UK. Using a hotspot connected to the internet is no different than using a local repeater connected to the internet. Kind regards, Phil

    David, Maybe not want you want the hear but I had the same problem with my 991, couldn't get the updates to work. Was told it was the lead, purchased a new one had some given but finished up with five in the end but still got so far and then said can't find com port, took it to the dealer twice (half day road trip there and back) for two updates then update #3 didn't work so after 14 months traded it in for an FT450D. Love Yaesu radios but the SDR type radios are not welcome at this QTH!! Get someone with a Lap Top to pop around and try that way - Good Luck hope you get it sorted.

    Hi i am very interested in getting a dmr uhf radio. I want to use the radio with a internet hotspot to make new friends and socialise with new people. I have bought a uk foundation licence book and will be working up to passing a foundation level licence. I would like to know if this licence would allow me to connect and chat to talk groups outside of the uk or would i be restricted to chatting to only hams within the uk? As i would only transmit on 1w to the hotspot i would meet the power output restriction but im finding it hard to work out of if this would legal or not. Any help or infomation would be greatly appreciated. Thank you

    Well after playing with new FT991A, lots of fun , but decided to read & reread the Update manual for Firmware. everything seemed to install the Main YFSWO24 & AHO67 ****.SFL files. Did reboot as per following exact instructions, step by step.... Went to install the TFW.... & this is where it won't connect to port to allow com port for update stage... If I knew the FT991A was going to be so difficult to update this unit I would have got the Ham store do it.... I tried to redo procedure to no avail, now the terrible thoughts of shipping & cost to have the unit fixed cause of my lack of computer programming skills ... Any advice would be appreciated :distress: VE7OPL David
