Antenna Tuners For Sale
Antenna Tuners For Sale: . Nye Viking MB V-A High Power Antenna Tuner For Sale: The rugged Nye Viking MB-V-A 3 KW HF antenna tuner features a silver plated variable inductor with a vernier dial, 7,000 volt variable capacitor and 15,000 volt switch selected capacitors. The frequency range is 1.8 to 30 MHz continuously. Dual metering provides for hands free SWR monitoring. The backlit dual meters show SWR and power continuously. You get push button antenna switching from the front panel. Outputs are provided for two coaxial cables, one single wire and one balanced line. The extra heavy gauge aluminum cabinet provides effective shielding. This tuner is a real brute; they rate it at 3000 watts, and I believe it. Cosmetically, this one looks close to new. Both the SWR meter and power meter work, including the lamps. It uses a 9 volt battery. It will tune most any thing. Everything is 100%! Buy this great unit with paper work for $400. . Dentron "Super Tuner Plus" For Sale: The Dentron Super Tuner Plus is a heavy duty antenna tuner covering the HF bands from 160 thru 10 meters. It is extremely rugged. The manual says it will handle 1000 Watts CW and 1200 Watts PEP SSB. The "Plus" indicates that it has a built in output meter on it. The built in balun is very large. Much larger than the baluns in the MFJ tuners. This one works fine; it is built like a tank! Cosmetically, it looks great. Buy it with paper work for $145. . Vectronics VC-300 DLP Antenna Tuner For Sale: The VC-300 DLP lets you tune any antenna from 1.8 to 30 MHz, including MARS and WARC bands.

The VC-300DLP backlit Cross-Needle Meter display shows SWR, forward and reflected power simultaneously. It reads both peak and average power on 30/300 Watt scales. Meter lamp has front panel switch and requires 13 V DC. The VC-300DLP antenna switch lets you select two coax fed antennas, random wire/balanced line or built-in dummy load for use through your tuner or direct to your transceiver. Bypass position bypasses your tuner but keeps your SWR Power meter in line. A dummy load is built in. This tuner is much more rugged than most of the MFJ tuners. This one works 100% as it should, and looks very close to new. Buy it with paper work for $120. . MFJ 949B Antenna Tuner For Sale: The MFJ-949B is designed to match virtually any transmitter to almost any antenna. A 4:1 balun is built in.

To read reflected power simply turn the FUNCTION switch to 30 or 300 on REF. The ANTENNA SEL. switch allows selecting two coax antennas either direct or thru the tuner, a balanced line antenna or wire antenna or a built in 50 ohm dummy load. The 50 ohm dummy load is rated at 200 watts. This one looks great, and functions 100% as it should. Buy it with paper work for $100. .

MFJ-1263 9
Hello, I don't know if I'm being stupid or I just cant see it in the manual. I have a Yaesu FT-847 and an FT 101D I use a mix of Microphones, But want to tidy the desk and only use two so I bought the MFJ-1263 Microphone/Radio switch. (Microphones are Yaesu M100, Heil Pro 7 and Heil HM12 and MH31 on the Ft-847) I can't seem to find any information on the pin settings for Yaesu to Yaesu in the manual. Like I stated, I'm probably being stupid and am missing it completely. Please put me out of my misery.

MFJ 1898 Collapsible Antenna 8
Hello: My first post and I have had a reasonably good experience with the MJF products. Just before MFJ announced their closing, sad for amateur radio. I purchased the 1898 collapsible antenna which came with no directions. My question, has others used this antenna? Do you have any tuning suggestions, I find it a bit touchy to tune. Or have you worked out a Tuning Chart for the bands as to how to set the lower and upper sections ? Thanks Charles W5CRY

Troubleshoot an Ameritron ALS-500 Remote control 3
wonder if anyone on the list has a schematic of the ALS-500RC? I don't see one on the MFJ website. Or , can anyone suggest how to trouble shoot one that doesn't seem to be working with my ALS-500? Your assistance will be appreciated.

ALS-1300 and ALS-1406 compatibility
I would like to know if anyone has tried using their ALS 1300 power supply plugged into their new ALS-1406. I just ordered a 1406 and am hoping the power supplies are interchangeable. That would make a nice backup situation.

MFJ-998 tuner Excessive RF Radiation 11
Has anyone experienced excessive RF radiation from their MFJ-998. When I run a signal (any mode) on 80m more than 70 W through the tuner I have adverse effects from several devices including my oven, computer monitor and remote controlled lights, all devices have RF chokes on them. When I bypass the tuner I do not have the same issues.

MFJ 1263 Yaesu - Yaesu pin set 2
I'll try this again with some photos this time. Help needed as I'm still drawing a blank on this. Hello, I don't know if I'm being stupid or I just cant see it in the manual. I have a Yaesu FT-847 and an FTDX101D I use a mix of Microphones, But want to tidy the desk and only use two so I bought the MFJ-1263 Microphone/Radio switch. Microphones are Yaesu M100, Heil Pro 7 and Heil HM12. I will keep the Pro 7 in line all the time and mix between the other two. I can't seem to find any information on the pin settings for Yaesu to Yaesu in the manual. Like I stated, I'm probably being stupid and I am missing it completely. The factory pin settings don't work. Please put me out of my misery. If you have a similar setup, please share your pin set photos.

1708B-SDR
When I use the 1708B-SDR it will occasionally put the radio in transmit. This doesn't happen if the unit is not in the loop. At first I thought it was RFI so I have toroids on everything and a common mode choke on the coax from the antenna. Only happens when I am using the 1708. It happens if I just use RF sensing mode or in combination with CTRL to PTT. Any ideas?

MFJ-993B LC Limits 2
If anyone has any experience, could you please tell me how this adjustment is performed. From my reading by default it's prevented so high voltage and damage won't happen. It's suppose to allow slightly more or less capacitance and inductance than what's available by default. I run low power and wanted to find out if either more or less cap/Ind would help with some tuning. I have read the manual a few times and I am still a bit confused how you extend the range. thanks Ken N1KK

Autotuner for Drake R8B? 3
I would appreciate recommendations on antenna autotuner for receivers Drake R8B and Drake SW8. I am not a ham, but have listened to SW and ham operators for the past 65 years. I'm 73 years of age and thinking maybe it's time to get licensed (not sure my brain could do it.... lol). My radio shack (tool shed) is arranged so that my radios and existing MFJ-959C tuner and antenna switch are kiddy corner to my Dell AIO computer and TV (to avoid interference). I control the R8B with Fineware software from my computer. I have two antennas, a Delta DX-SWL sloper (60'), and the MFJ-1886 loop antenna with rotor. Instead of getting up and walking to my radios, I would love to have an autotuner to do the work for me. Any suggestions? Thanks in advance. Bill

S-match tuner and MFJ modification 2
While researching balanced tuners, I ran across a website that describes the "S-match" tuner. https://pa0fri.home.xs4all.nl/ATU/Smatch/smatcheng.htm Digging a little deeper revealed a detailed modification of a MFJ-989 to an S-match. https://pa0fri.home.xs4all.nl/ATU/MFJ-989D/MFJ-989D%20conversion%20to%20S-Match.htm Has anyone here done that and if so, what were the results? More generally has anyone used an S-match and how well does it work? WB6YZZ Prineville, Oregon

Howdy; Looking for help or suggestions here. I have an MFJ 1278 original, not the b version. It will not respond to signals coming in, but will transmit tones and the Digi I am connecting to responds. I am looking for a better schematic. I have the book, but the drawing is small and hard to see. Don't know if doing a scan will work.manual is for rev 2, my board is ver 7) Anyhow, this is driving me nutz, and looking for help or suggestions. Thanks 73 Mike - N7ZEF
