tuner

so i built this linear loaded SWL antenna, a project i found on the swling website, which involved getting a a NooElec 9:1 balun in the middle of two 15ft pieces of romex bound at the ends in a way that it effectively makes a dipole with 45ft elements. this balun is not made for any kind of...

When I try to tune my IC7100 at frequencies lower than 20m, the tuning signal ramps up and resets over and over... it wasn't always like this, and I'm sure I've changed soemthing to cause it, but I have no idea what. Works fine 20m and higher - anyone have any ideas? (video link below of it...

Greetings all, I have an Icom AH-4 long wire antenna tuner that is not working. Checked it inside the case for the usual suspects like burned components, cold solder joints or anything else obvious but the unit will not tune up on any band. Looking for a shop in Georgia familiar with this item...

i'm new to HF... and as i posted in a different thread i'm considering an MFJ Octopus, which is effectively a fan dipole. i have to choose 4 dipoles made of hamsticks to put in this - which will connect to my tuner. i was watching one of Dave Casler's videos (the man has taught me so much)...

relatively new to HF, everything i've done so far has been FT8, and i was super proud of the 20m dipole i built... until a branch fell and did epic damage to my house and took out my dipole in the process... my MFJ tuner couldn't get my 20m dipole to work 6m, so my plan once the roof is...

new to HF here, always on FT8... i have been using a 4010 EFHW for a few months with an MFJ939i tuner to my IC7100. I was always able to tune the EFHW from 40-10 as expected but could also tune it to 60m and 80m and even 6m. but i had to position it in a way that was causing RFI into my...

Hi, I've decided to remove a EFHW antenna I had and put up a end fed long wire antenna attached to a FC40 tuner as I wanted to try to get 160m to 6m The tuner is right outside the window of my shack and the cable goes up 9 metres on a budget flagpole across 14 metres to a 12m Spiderbeam. The...

Greetings radio people. I have a remotely controllable AM/FM broadcast band tuner which I stream to internet for my own private use, although the stream is not protected in any way. I put up the stream so that I could listen to my radio at home when I am not at home. This radio is located in...

Hi, I have a LB CDM1550 radio that has its squelch set too tight. The squelch breaks at ~-111dBm or .63uV. I need to readjust the radio so squelch opens at ~-120dBm or .21uV. Using a comms tester I read the radio using Moto's Tuner app (admittedly I have only used CPS in the past and have no...

Hello, I have an Icom IC-745 radio that has a new problem. When you power the radio on, the frequency indicator and the radio itself starts to constantly tuning down all the bands at a slow but steady pace without touching the knob. If I hit the lock button it will stop tuning down but...

Hi Yaesu FT-600 (SYSTEM 600) is an old rig. Its manual states FC-800 as its external tuner. I've found a FC-30 for sale (which is rather a new model) but I don't know if I can use it with my rig. Anyone here has the experience? (With Icom, you usually can use any rig with any tuner. They have a...

I found that once you train the tuner to your antenna, and you then improve your antenna, so you SWR goes from 3:1 to 1.5:1 on a particular band, the tuner will not be triggered into tuning on a frequency that it already has in memory. So you will see your SWR is higher than you know it should...

Just happened across a FC0013-equipped EZCAP stick that someone gave me because "it wasn't as good as their new E4000-based one". I fired it up and compared it against another E4000-based RTL stick head-to-head in dual SDR# windows with identical whip antennas. My particular FC0013 sample...

Hello All, I recently bought an 800 MHz radio off of eBay and have run into an issue. I am able to read/write the radio using ASTRO Spectra CPS Version R05.03.00 just fine. When I try to read the radio with ASTRO Spectra/Saber/XTS3000 Tuner Version R01.03.00 the radio will not read. If i'm...

Does anyone have any good recommendations on a good tuner for random wire antennas on HF band? I am receiving only shortwave broadcasts and wondering if a tuner would give me a decent signal over what I have now. Any suggestions or info would be great. Thanks

Hi, can any one please tell me what kind of cable/wire should be used between an Auto tuner & antenna. The antenna tuner is a Barrett 911 ( 911 Automatic antenna tuner ) the antenna we have is a 18-20 foot aluminium vertical with just a single screw for connecting the wire from the tuner to...
