Re: FC-50 Tuner?

Have not used nor do I own it but from some reviews it has a limited range (one quoted 3:1) so if this is true anything far out of resonance will be a no go with this tuner.  Not necessarily a bad thing but just have to be aware of this.

FC-50 Tuner?

#324

Anyone use the FC-50 tuner yet? I have an FT-891 and the FC-50 tuner. I am still working on antennas and the the General class license, so I have not tested anything yet.

Just checking in to learn about the tuner. Thanks.

Will be very interesting. The fc40 does a good job if the antenna is complemented with a unun/balun.

Thanks Jerry. It looks like the fc20 and fc40 use different wiring too!
I think that the key information that I'm looking for is how the tuning command is initiated. It seems that the fc20 is the master and polls the ft100 to check for the TUNE button. Taking over, it sets the ft100 for tune power until it's happy with the swr. But I can't find confirmation of that.

Now looking at serial comms sniffing tools to find out what these two are saying to each other before and during the dance!

Probably of no help,? I have the FC40 ATU the schematic shows all the signal wires going directly to the main processor. The pins are tx inhibit, reset, sense, data in/out, gnd, tx gnd and 13.5 v.?

Interested in following this up. (I have asked the same question on the FT100 forum/s)

Short answer - I haven't found anyone.

Longer answer ….

Clearly, the antenna tune mechanism is fundamentally different to ATAS tuning, where the TRX (FT100 in my case) provides a dc control voltage for the antenna?and monitors SWR during tuning itself.
It seems that the FC20 is continuously checking the FT100 status using CAT and captures a TUNE command. It then takes control of the FT100, sending back tx mode, power and key commands to provide an appropriate rf level. It does this until the FC20 is happy with the SWR.
That description is guesswork, however, based on what I observe doesn't happen and on how I would use the available signalling.

So the problem is that FC20 is continuously keeping the CAT interface busy and that's probably why it's not easy to share the CAT port.

I believe, however, that nothing's impossible, it's just the degree of difficulty. I can see a solution where a PIC sits in the CAT interface monitoring the comms between the CAT program (say HRD?) and when the TUNE button is pressed, or HRD commands it, the PIC switches the CAT to the FC20, or even emulates the FT100 on a separate tuner data lead. It's only programming,?after all.

I looked into the bhi CAT-Mate. It uses a solution where a monitor switches the CAT lines between two CAT devices?but the manufacturers unambiguously state that this 'Y' unit won't support a tuner on one of the two CAT ports. So the technique is valid but the FC20/30/40 use a different protocol to other devices.

The LDG tuners (YT100 and Z817) also use the CAT interface to set the FT100 to generate an appropriate tuning signal.?As the TUNE command is issued from the button on the ATU, rather than the FT100,?it can switch the CAT control from the PC to the Tuner whilst tuning and then back when tuning is complete. There's no need to monitor the FT100 status for a button press. The LDG tuners have a CAT passthrough port which works in this way. Indeed, this is one solution for me - to replace the FC20 with a YT100 and then add in a PC driven switch contact to 'push' the YT100 Tune button using HRD.

If you find any detail on the FC20 protocol - that is, have I guessed correctly - then I'll happily work with someone to develop a solution. I have a perfectly good ATU (FC20) and don't want the expense of changing it just because I want to remote control the station using CAT!??

Re: FC-40 Flexibility

#319

Build a fan dipole (several parallel dipoles each for a specific band)

Then your internal tuner could tune that with ease

Autotuner like fc40, sgc (xxx), and some other can easy be used for tuning a
dipole, doublet or a loop.... but the tuner has to be "floating" rf wise

Means ... put a choke on the INPUT of the tuner and also choke(s) on the
power lines ... the tuner has to be isolated from ground if you wanna tune a
doublet or loop

I used my fc1000 that way (on fieldday setup etc) ... and a friend from me
uses an sgc tuner that way

I decided to go ahead and get the radio to see what could be accomplished
with the internal ATU.  I installed a 2 band dipole (10M and 20M) and the
radio will only autotune on those 2 bands so I'll still be searching.

If you have not bought the FC40 look at the SG230. A way better tuner. I have found the FC40 to be temperamental wrt wire lengths.

Re: FC-40 & Raingutter Antenna

Yeah - it stopped working again. I had disconnected it from my FT-897D and run a different antenna off a LDG-897Plus ATU for a week. Reconnecting, it fails to function. Full un-install, re-install, re-set DIPs, etc. And all bands HSWR - again.

I figured that, once it started working, that I'd hit on the magic combination of rubber chickens and wires that would stick. But no. I've never owned a more frustrating device.

Re: FC-40 & Raingutter Antenna

The FC40 is an odd duck tuner. POS comes to mind.  Mine now sits on my shelf reminding me how much I like my SGC 230.

       I switched to 107ft and 85ft random wires and still
 wasn't having any luck. I switched out to a new
 controller cables, added a lot of Mix 31 ferrite rods, and
 added a second ground rod wired to AC service entry ground,
 I added a few more counterpoise without success - no go. The
 FT-897D just went into tuning mode for a second and then
 displayed HSWR.

 I switch my
 FT-897D power supply from a FP-30B internal to a FP-1030A
 external, so I could go portable, and the FC-40 is now
 working from 6m - 40m. It takes a few seconds to tune, and
 only indicated HSWR on 80M and 160m, which is no
 surprise.Switching out between the FP-30B and FP-1030A
 again, I can confirm that the FC-40 works with the external
 but not the internal PS. Very odd...

Re: FC-40 & Raingutter Antenna

#313

Hmmm ... rf floating on coax braid towards the rig???

What antenna are you usin and what round system has the tuner to work
against?!?

Had similar trouble on filedday with my fc1000 (also an autotuner by yaesu)
... adding some (loner) radial wires at the tuner and all was fine

The tricky thing is the tuner has something to work against ... and
sometimes it is not only your round but also the coax and other wiring that
the tuner uses as the other half of the antenna

Next is length of the wire

If it is close to halfwave you have very high impedance and voltage at the
feedin point ... no good for the tuner

So ... sometimes a small chane in length does help for the tuner finding the
right match

I switched to 107ft and 85ft random wires and still wasn't having any
luck. I switched out to a new controller cables, added a lot of Mix 31
ferrite rods, and added a second ground rod wired to AC service entry
ground, I added a few more counterpoise without success - no go. The FT-
897D just went into tuning mode for a second and then displayed HSWR.

I switch my FT-897D power supply from a FP-30B internal to a FP-1030A
external, so I could go portable, and the FC-40 is now working from 6m -
40m. It takes a few seconds to tune, and only indicated HSWR on 80M and
160m, which is no surprise.Switching out between the FP-30B and FP-1030A
again, I can confirm that the FC-40 works with the external but not the
internal PS. Very odd...

FC-40 & Raingutter Antenna

[email protected]

#311

I was using raingutter antenna with my FT-897D and was able to pick up quite a lot of chatter on 20m, 40m and 80m. The gutter downspout was connected to my MFJ-898D tuner wire post and a set of 1/4 wavelength wires for 10m, 17m, 20m, 80m were connected to my tuner ground.

Today I connected the 12g insulated gutter wire to a new Yaesu FC-40 autotuner and ran a 12g insulated wire to a ground rod. The tuner cannot tune any band 6m-80m and I get HSWR on the FT-897D display.

At present, the FC-40 is mounted inside my garage and I am running the wires to the downspout and ground rod ?around the corner of the garage door together side-by-side. This was a quick-fix instead of drilling holes to the outside to bring the downspout wire and ground wire directly to the FC-40 posts. Both wires are side-by-side for about 4ft and the ground wire extend another 2ft to the ground rod.

I was surprised the FC-40 couldn't tune any band, as I was able to find numerous frequencies with SWR <3, between 2-3 and <2 with my MFJ-269 analyzer.

Any ideas?

Nice offer

Yepp ... fc1000 is a VERY good remote tuner (i also own one)

And you are correct ... can be used with nearly ANY 100w class trx

You only need ptt, agc and 12v

#307

Hello all.  My name is Jeff, callsign K4LMP.  I just joined the group, and wanted to say hello.  The moderator was interested in what type of gear I had, so I just figured I would start a post, and say hello, and list my gear.  I have an FT-897D, for which I have an FC-30, as well as an LDG AT-897.  I also have an FT-101EX, with the external VFO, digital display, dummyload/wattmeter, landliner phone patch, station monitor scope, external speaker, world clock, and 2m transverter.  All I lack having a complete 101 station is the FL-2100B amp and FTV-650 6m transverter.  I have an Alinco DX-70 mobile rig in my shack as well, with a LDG AT-100pro tuner.  My mobile setup is an FT-8800, with a Kantronics TNC for mobile packet, an FT-857D for HF/6m with an LDG AT-100 Pro II autotuner.  I run the K4LMP-R Echolink node, as well as the K4LMP-10 Winlink RMS Gateway.  I also run the MSYS BBS on our local packet node, so, as you can see, I have several dedicated servers running 24/7 devoted to ham radio.  I am in the process of putting up my 60 foot Rohn 45G tower.  I joined this group, because I have the FC-30 autotuner, that I orignally bought with my 897D, just sitting in the box.  It works great, as long as the SWR is not too awfully high.  I thought there might be some tips to use it more efficiently.  Glad to see this group, and hello to all.

73's es God Bless,
Jeff K4LMP

modifying the fc30

#306

hi ken here,has anyone tried to improve the 30 by adding extra capactors,their surface mounted and not a lot of surface ares to solder to,I built a unit with extra capacters which were switchable on the output of the 30 and it tuned a lot better with the extra caps,they only need to be paralelled up to the fitted ones,regarding the coils,they have to be in serias with the origanals,eg making the coil longer, if Ihad seen the spec of the ldg at 897 i would have gone for that one,the 30 is only 1/5 the spec of the lgd,say no more,regards ken,m3zkb,rafars 4680
