MFJ 998 part needed
2
Hi fellow operators I am looking for a power switch and button cap for my 998. I have pretty much exhausted thingybay and amazon, Aliexpress etc are a no go and I cant find a UK stockist that does that size of button cap. The 6 pin switch I can source so can anyone point me to either a complete switch/button cap assy or just the button cap please. Failing that has anyone stripped one for spares? Regards Garry.

Schematic MFJ/Vectronics VEC-1380

I'm looking for a schematic for the VEC-1380K. I picked one up at a recent hamfest. I want to get into it possibly modifying it for lower down the band. The only schematic I can find is the downloaded pdf from MFJ or the various manual download sites. All of them are basically unreadable even when I max out the print quality on my printer. A clean scan of the printed manual would be great. Thanks. 73 Clif K5LIF

All, This does not seem right.. Powered on ANT to XCVR= -50DBM to -35 DBM ( 2 Mhz,30Mhz) ANT to SDR= -2dbm across frequencies 2-30 Mhz Power on in TX Ant to XCVR= 0DBM Ant to SDR= > -60 Dbm across band 2-30 mhz Question is WHY is there a 2 DB Loss from ant to SDR in RX ?? and why is there a -50 db loss to XCVR port.. Seems that it should also be 0 dbm for both.. HELP Skip PS MFJ doesn't respond to my emails..

Changing The Coax Connector on MFJ-4601, Window ANT Feedthru

I have an older MFJ-4601, I would like to change one of the SO-239 to a “N” type connector. I was wondering how hard is this going to be? Are the panels glued to the board? I don’t want to destroy this in the process. I have a 1.2ghz antenna, it uses “N” connector. Thanks in advance. Thomas Mackell Sr KI4FRU Sent from Mail for Windows

Scammer "MFJ" website
There is a scammer site that's been reported to the FTC. From MFJ's site: "There is a SCAM website currently advertising as MFJ. Please be aware that this site is not MFJ Enterprises, Inc. We have reported this to the Federal Trade Commission. Do not purchase anything from scammer website." This is the REAL site: https://mfjenterprises.com/ Also note that if you allow them to have your email address, you can get a free copy of a book, 73 DIPOLE AND LONG-WIRE ANTENNAS. There is a link on the above page to do that. HOWEVER, their link to subscribe and get that is broken. I suggest contacting them and arranging to get the book for free. It's not a book you'd sell your soul for, but it's free, and it may give some members ideas on simple wire antennas. The book is for sale for $24.95, a bit overpriced in my opinion, but they appear to have bought the rights to it and it's out of print except there. To do this ethically, you should sign up for their email list, but I don't see how to do that with their broken site. Then you are taken to the URL below, where you click on the words: "Click Here" and that gets you the publication at the URL below. So you can get it there if you wish; it takes you to a Google Drive document in PDF. It's an OLD book, first published in 1969, and I think it was then distributed by 73 Magazine, a Wayne Greene publication. https://mfjenterprises.com/pages/email-list-sign-up-completed?_pos=3&_sid=f814406ff&_ss=r Donald KX8K ---------------------------------------------------- Some ham radio groups you may be interested in: /g/ICOM /g/Ham-Antennas /g/HamRadioHelp /g/Baofeng /g/CHIRP https://rf-amplifiers.groups.io/g/main

MFJ 993B Intellituner & 30 meters (10MHZ)
2
Hi I am using an Icom 7300 with my MFJ 993B Intellituner with the MFJ interface cable. I notice today that the tuner would not tune up 10MHZ. I normally tune at 20 watts power. But then again if the antenna is already resonate for that frequency then I may not see anything happen I do not know. I normally tune anything from a 3.5 swr to 1.1 swr. Thanks

MFJ-993BRT
I recently made some repair work on my MFJ-993BRT tuner. Unfortunately I forgotten to check the followig: 1. Can the switch board (atop the main pcb) be easily removed? 2. IMO the tuner should work normally with the switch board removed. 3. Is the microcontroller U1 (PIC16F76-I/SP) read protected? Thanks for any reply, Robert W4BCZ

MFJ -993B autotuner
4
Anyone using an MFJ-993B with an MFJ-5124Y interface cable to a Yaesu tranceiver? I have been attempting to get the unit to work correctly. At low power it autotunes correctly; when I increase power the SWR increases so that I have go through the retune process several times. MFJ tech info service is useless and is no help, as expected. Is it just this unit or is it common behavior. K3YZ
