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

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.

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

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...
