High SWR, no receive on HF

 

I recently had a friend help me fix a cracked solder joint on the speaker jack of my FT100. The fix worked like a charm. When we finished, we went onto 20m and there was absolutely no sound on SSB, AM, or CW but lots of static on FM. This is universal, all bands. Also on transmit I get the high SWR warning even though the SWR is low (I was transmitting on a tuned Buddipole).

The radio has the 6m SWR mod and the fan mod. I've searched for articles that might apply and offer some troubleshooting, but none so far. To perform the repair to the audio jack, we of course had to remove one of the main boards. When we reassembled it, we traced everything back and it all appears to be fine, but I'm wondering if there's something cross-connected (traced back means we had the schematics out and followed each circuit).

Has anyone seen something like this before? Any recommendations on where to start fixing it? Or does this just sound like it needs a trip to the "FT100 Repair Shop" (Burghardts)?

I'll throw this out there - this radio will be on QRZ for sale shortly, repaired or not. The radio is complete - including separation kit, mounting bracket, manual and original box. It was a backup rig for the previous owner. It was my mobile unit, then my base station, and then just sat in the box for several years II've owned it for 4 years, used it for maybe 1 in total). I'm willing to discount it the cost of a thorough going-over from Bughardts (I understand that's a couple hundred dollars), so I'll take reasonable offers for the complete kit, if anyone is i nterested.

Why selling? I've remarried and moved, and merging two families along with my job means I have limited time for radio. I've gone completely portable, am learning CW, and really only operate from the back porch or the backcountry. No sense in this rig sitting unused, and I need to "fund" a few purchases. With 3 kids in college, that means I have to sell something to buy something!

Thanks and 73's
John K7JTO

My FT-100 draws 10 amp on RX

 

Hello all,
I hope someone here will be able to help me with my problem.
I was testing my FT100 on a dummy load (what an irony !!!) on the HF bands and suddenly the high SWR icon appeared.

I didn't realized at first what happened until I noticed my power supply ammeter showing about 10 amps on receive. The radio is getting very hot from the hf finals without transmiting !!!

As far as i can see (I disconnected it immediatelly form the supply) no smoke or burned components. Of course something must be burned but I cannot see it.

Can you help me where to start or does anyone know a good service center in Europe because I'm located in Greece ? 

Thanks in advance
Fanis, SV1BGM

    FT-100D - Perfect Condition - With Separation Kit

     

    Hello fellow FT-100 Group Members,

    I am the original owner of a Yaesu FT-100D in near perfect shape.

    Bought it brand new and the only time it has been open is when I sent it to the factory for updates when it was one year old. Factory recommended 6M false SWR indicator update & fan upgrade as well.

    No modifications or repairs have ever been done to it.  Works Great, Hate to part with it, love this rig, but it has to go.  I have rarely if ever run any of the power levels above 50%.

    It was mobile for a year, you can't tell, and used base since.  Rarely used, just too busy.
      The microphone and cord are perfect, I replaced the cord when taking it out of mobile service, so it is not stretched out or brittle at all, like most that are used mobile.

    Make sure to look up all of the extra options the "D" model came with if you do not know. Digital Signal Processing, filters and such.  The DSP and NB were invaluable when used mobile.

    The selling price is $650 with a YSK-100 Separation kit, which I bought used on Ebay.  That alone was $120, more than the retail value nowadays since they are so rare.  I have never taken the YS K-100 out of the box since I bought it used.

    I have the Owners manual and the non-documented features manual, as well as the original marketing flyer / spec sheet all 3 in PDF format which I will email you when you buy it.

    I have the original box, mobile mounting bracket & screws, as well as the schematics (paper copy).

    Worked awesome with Ham Radio deluxe with just 2 cables, no other hardware or adapters needed for most any digital mode or any of the transceiver control functions.  Like having a Software Defined Radio, with the FT-100D box as the transceiver deck.

    What else would you like to know ?

    How often will you find one of these that is in new perfect, like new condition, original owner (I am talking myself out of selling it), with a separation kit and at a reasonable price too ! ?

    SWR, no output

     

    Hi folks, hey... I dusted off my FT100 recently to get it ready to sell. Had to fix a cracked solder joint on the speaker jack. The fix worked like a charm.

    Does this sound familiar? Any recommendations on where to start fixing it?

    Question regarding DATA jack (audio-in) and SSB mode

     

    Hi guys,

    I have a question and I hope you are able to help me. Unfortunately I
    am currently not able to check it myself.

    Is the audio in of the data jack also active in SSB mode, e.g. could
    this input be used for a soundcard voicekeyer?

    The reason behind my question is the following paragraph in all
    Microham Interface manuals: "IMPORTANT: Many transceivers, including
    all Yaesu transceivers, MUST be switched to special digital mode (DIG,
    PKT, DATA, USB-D/LSB-D etc.) to enable the rear panel line input!"

    Is anybody using this FT-100 in combination with Microham hardware and
    uses the soundcard as a voicekeyer in USB/LSB?

    Thanks in advance.

    73
    Christian, DL6KAC/EA6 (currently of air due to ALC issues of the radio)

    Are you TRANSMITTING on a ham frequency? CHECK the displayed frequency WHILE ATTEMPTING TRANSMIT, if it CHANGES from what you had during receive, SPLIT mode  may be engaged! (If this frequency is outside the band, NO transmit is the result!-73, KC3VO,Bob Curry

    I have had the FT100 (not D) for several months in the car and had maybe a
    couple of qsos on it, it has otherwise simply been used for listening,
    mainly on 2m FM.

    When I went to transmit the other day I have no output on any band.  I have
    performed a re-initialisation but no luck.

    Any pointers please?  Is this the too high standing current issue I have
    read about before, and should have checked?!  There are so many references
    to this in the archive that I'm rather confused.

    tnx and 73,
