    thanks that's great to know so have at least eliminated one so then I'll have to narrow down between the mfj 956 which is an antenna tuner and preselector or the mfj 959c which will do two radios off one antenna so I could have my own alinco and grundig satellite 750 hooked up and definitely balanced the line to the receiver but it doesn't have a preselector and the increase in signal-to-noise ratio I have not mastered yet but that's half the fun!! If the antenna was already match the mfj 1046 Passive preselector would be the best but from what I've been researching without an antenna tuner I am missing signals out there. Any experience or knowledge on that is that true?

    Read. The. F***ing. Manual. How dare you sir! I'm an engineer, to suggest such a sensible course of action is heresy! ;) Many thanks for that - to be honest, I had never noticed it before and I'm pretty sure I have played with all the knobs, buttons and twiddly bits before. Most embarrassing!

    There is nothing wrong with your radio. This is normal operation for the RF gain control. If you have the operation manual, see page 11. Otherwise you can download it from http://www.icom.co.jp/world/support/download/manual/pdf/IC-735.pdf. From the manual: "This control varies the gain of the RF stage when the transceiver is in the receive mode. Slide the control upwards for maximum gain. Note that as the control is slid downwards, the 'S' meter needle rises, and only those signals stronger than the level indicated by the needle will be heard. In the FM mode, regardless of the control setting, the RF gain is fixed at the maximum."

    Auto-ATU's usually need a transceiver to work. Go for a simple manual type tuner - you won't need anything elaborate for a receiver. An ATU (at its simplest) is simply a variable capacitor and a tapped inductor. Search for L-match or Π-match and build one for around $10!

    I just installed 160-6 meter 117 ft wire fed antenna with a 9:1 Transformer the qso king from mapleleaf and to be honest it really works great for my alinco dxr8t I need to have it set on 20 + decibel to hear however I do need an antenna tuner and I was wondering between the mfj 956 the mfj 959 C and the mfj 1046 which would be best for receive only the mfj 939 is an automatic antenna tuner that might be a route to go to and it saves memory Has anyone used any of these on long wire fed antennas and could recommend which one they think is best thanks so much

    WZ7U replied to a thread TS-480 Finals in Kenwood
    How do you know the watt meter is calibrated correctly? Is this an external meter or one built in? I ask because it seems that one antenna terminal is connected to the internal tuner & one isn't if I'm reading the manual correctly. Next thing that comes to mind is are you generating a single, solid tone or a series of dahs/dits? That might explain the discrepancy. Is the power turned down in a menu somewhere? 80 watts is too close to rated maximum for me to suspect bad finals. I'm more inclined to think peak vs rms meter readout or something as sublime as that. Can you transmit in RTTY and see what you get? Manual here - https://manual.kenwood.com/files/4fb9df09b7216.pdf

    Personal suggestion, go tho this link, https://www.icom.co.jp/world/support/download/manual/disp_down.php?SWT=&ID=20010101116&GNR=Amateur&TYPE=Base%20Station&PDNM=IC-735&INQWORDSWT=No&INQWORD= , download the manual, and start from scratch. I did this with my 757gx and found some very interesting things that assisted with setup and running the transceiver. 73s. God bless and good day. KD9KVS I have a brain injury.

    My ICOM IC-735 has been working OK for several years, but I have hardly used it as I didn't have a decent power supply. Last week, I finally got one. I hooked up the radio and... nothing! A symptom of the fault seemed to that on power on, there is burst of regular noise from the speaker, but then it fades to nothing and the needle of the S-meter moves fully to the right. I pressed just about every button, clicked every switch and twiddled every knob, but to no avail. A couple of net searches later, I thought I had found there answer. An thread from some other forum indicated that the problem could IC8 (CD4021) in the PLL circuit had died. So, I replaced it. The problem is still there. While poking around a bit more, I slid the "RF GAIN" slider all the way and the needle returned to the left and the regular radio noise came back. Moving it up and down, the receiver goes dead and the needle moves.

    There's nothing new about vertical dipoles. Just few suggestions: The higher from the ground the better. Run the coax away from the feed point at 90 from the vertical for as long as practically possible or if you're using tubing, run the coax /through/ the lower element. Virtually every book about aerials for amateur radio will cover using dipoles vertically polarised.

    OH8GAD replied to a thread Upgrading a handheld in Amateur Radios
    I would say neither, until you know what you what from "upgrading". I mean, what can they do, that you need, that the Baofeng UV-5R cannot? If you need more range, then build a direction aerial. Seriously, a few watts and a good beam aerial go a looooong way! If you find just using FM is restrictive, but want to stick with 2 metres and 70 cm, then look for a radio with SSB. But to get the most from that, you will need a direction aerial too. If you want to use a digital mode, such as DSTAR for example, then you need to decide which mode you want (i.e., which is used most in your area) and ind a radio that supports that.

    IMHO I would stay away from both of them until CHIRP supports one or the other. Do either of them have software for programming or are you a program from the radio kind of person? Sent from my iPhone using Tapatalk

    Okay, So I'm nearing a year with my Baofeng UV-5R V2+. I'm interested in upgrading to a new handheld pretty soon. I'm looking at the Retevis RT82 or the Yaesu FT-70DR. What do you guys recommend?

    Does anyone know the number for the finals in a TS-480SAT and where I can get them? My rig only gets 80 watts out on CW with a watt meter and a dummy load connected and the rig tuned. I thought there was a way to bypass the tuner to test the finals, but I can not find one. Please help. 73's Dave

    WZ7U replied to a thread Using a Dipole As An Upright in Antennas
    May I suggest you will have better luck if you add at least two (or three) more 1/4 wave counterpoise elements evenly spaced around center, horizontally at the base. Not that what you propose won't work, it's just that you will get a more omni directional pattern from your RF output. This is commonly known as a 1/4 wave ground plane vertical, which is what you are proposing here. You shouldn't need any sort of UNUN/BALUN for this to be efficient, however the impedance will be slightly less than 50Ω, probably around 35Ω or so. You can bring the impedance back to around 50Ω by tilting the ground plane elements downward between 30 and 45. At least that's been my experience with the 40 meter 1/4 wave ground plane I put up here in CN86jc using 12ga wire and a big bamboo sprig. Check out my zed page for a less than stellar view of what I did. https://www.qrz.com/db/WZ7U I really should put up a clearer picture some day... Try these resources -...

    I ordered up some FT114-61 ferrites from Amidon planning to make a 10m 9:1 unun. However, when I excitedly wound it and soldered on a 450ohm resistor to do a sweep with my rigexpert, I was very disappointed in the SWR curve. What I did: 2 stacked FT114-61 ferrites with 11 turns (trifilar) of 18AWG solid-core insulated wire. The SWR is at 2:1 at 28MHz, I expected better. What I assume (from reading online, I'm not this smart): is that the more turns I use, the lower the self resonance and thus the lower the common-mode impedance at higher frequencies. I assume the higher I go in frequency, the more it acts like a choke. What I would like to know: 1st, is what I assume correct? And 2nd, does anyone know the optimum number of turns for 10m given 2 stacked FT114-61 cores?

    I had an idea to use my 10 meter dipole as an upright. If I put one leg up a tree, and the other out to the side as a ground plane, from my understanding I will have made a quarter wave upright. I am asking as much as stating. If anyone has done this please share your experience. Also making this adjustment, i should remain at 50 ohm resistance and have no need for an unun/unbal. any input on these thoughts are appreciated. KD9KVS I have a brain injury. I am not my brain injury. This does not define me. P.S. I appreciate all the input, for some reason my responses are not being approved. but they are coming once the button is clicked.

    I just got my ham license last year, and my first rig was a TH-F6a. I chose that radio because of its size and design, which I really liked. The problem is that all activity in my area is digital, and the F6 is analog. So after a year with a ham license, I still haven't contacted anyone. So I tried to get a digital rig, and my favorite was an FT1XD. I really don't like touch screens, so I didn't want an FT2. I'm more of a purist, and the FT1 is just my style. I wanted a new one, and I knew that the radio was discontinued and no longer available, so I thought I really lucked out when I saw that new ones were available from Japan. Not knowing about the band plan difference, I bought one. What a surprise when I found out the 'Error' I was getting on my club repeater's freq was because it was above 146. I learned about the mod for this rig, where you remove solder from the board in the hole in the back of the radio, so that's been done, and a reset has been done multiple times, but nothing has changed...

    Speaking of price gouging, I looked up the zastone zt-v8 I was gifted, they were 2 for <20usd now to find one at that price seems like a good deal. If I am remembering correctly, that was this past December they were at that price. Maybe I just happened upon a great deal. Just a thought.
