Re: REASONS WHY THE YAESU FT-60R IS MY EDC PORTABLE RADIO

 

One FT60R works just fine.? Print out this sheet of frequencies.


The FT60R allows you to program MEMORY BANKS.? Mine is programmed:
-- Bank 1:? Local 2 and 432 repeaters.
-- Bank 2:? All 2 mtr repeater pairs plus simplex
-- Bank 3:? All 432 repeater pairs plus simplex
-- Bank 5:? SO-50 programming from the page at the link
-- Bank 6:? Local public service freqs.

Program one of your memory banks to the AO-FO freqs.

Get an Arrow dual-band cross Yagi, handheld.
http://www.arrowantennas.com/arrowii/146-437.html

Watch one of the online sat tracking applications for when SO-50 is visible at your QTH.

When AO-50 is supposed to come into sight, point your antenna at the sky where the sat is supposed to be, FT60 on channel 501.? You will start to hear stations.? Call one . . . keep it brief.

Follow the sat across the sky with the antenna.? As the signal starts to fade, switch to channel 502.

Follow the sat, switching freqs as the Doppler effect causes signals to fade.

It sounds complicated but after a couple of sat passes, you'll have no problem with it.

Keep a tape recorder going (I use on OLD casette recorder) to ensure you get every call and contact.
Re: REASONS WHY THE YAESU FT-60R IS MY EDC PORTABLE RADIO

 

For years, the FT51R was my handheld.? Tried some others, none of them came up to the 51R -- reliable, bulletproof, good choice of accessories, easy to program, intuitive keypad.

I resisted the FT60R for the longest time then took the leap.? Took me a while before I replaced the 51R but the 60R is now my daily radio.? The old 51R is one the shelf; I pull it out from time to time for old times' sake.

Personally ?I think the FT 60 is one of the best radios ?ever made ...Well it has some shortcomings however the construction of this radio is unreal.?
I used to work on the Vertex Line of radios ?before motorola purchased vertex, the case material is the same on the Yaesu as there commercial line up they use black polycarbonate.. Not cheap plastic ...Awesome radio?
Re: Smart Search memories

 

You can force the scan to end rapidly by breaking squelch, either with the squelch button on the side of the HT, or by rotating the squelch control fully counter-clockwise.? This rapidly fills up the remaining search channels with noised will? once all channels are full.

Re: FT-60 audio a bit muffled just for m the radio no Speaker mic...

 

Thanks Chuck?

The membrane resides on the inside of the case of the radio ...It is not the rubber around the mic element itself ...Just tor clarify...To me it looks like a piece of Gortex material ...
Re: FT-60 audio a bit muffled just for m the radio no Speaker mic...

 

Well I did the mod and of course to me it sounds better and got rid of the Low Freq response.. Now I know it might be controversial however.."I did not remove the membrane on the Mic itself" Only the membrane on the inside of the case I folded it back on itself..

Yes that little worked I have much better frequency response now with less muffled audio... I am the owner of a Motorola APX 8000 radio and I have to say my Yaesu FT-60 sound almost as good now.

Re: FT-60 audio a bit muffled just for m the radio no Speaker mic...

 

The microphone inside the radio is an electret. The membrane to which I believe you
are referring too is a formed rubber dampener. The microphone is about 0.25 inch
in diameter and a cylinder about 0.25 inches high. Printed circuit board vibrations
on which the electret microphone is mounted are dampened by a rubber sheath
placed over the microphone. That sheath also has a lip that folds over and under
the microphone to mechanically isolate it from the printed circuit board. The gap
formed under the microphone by the rollover of the sheath is critical and the sheath
is in place when the microphone is soldered to the board.

The opening in the sheath for audio does little to alter the bass audio frequencies.
Rather I suspect the electret microphone simply is out of spec.? The diagram below
displays the covering cloth on a typical CUI design electret microphone. Notice they
show a 'non-woven fabric layer'. Also notice that is all that stands in the way of dust,
dirt, debris and spit encroaching on the inside of your microphone. You can remove
it, but you are inviting Murphy to throw a party down the road.

As the old label on radios and telephones use to say, "There are no internal
consumer serviceable parts". The pictorial below shows the assembled micro-
phone stack up. You can see why the fabric layer is critical to leave alone.


In all probability if your reports indicate poor audio, the microphone audio
response was bad from the beginning or debris and/or moisture has ingressed
the microphone. The fix is to replace the microphone. Last time I purchased
an electret from Icom (not Yaesu but Icom for an Icom repair) the microphone
was $1.35 and the shipping was $11.50. So call Yaesu and ask for the replacement
microphone. Alternatively if you can indentify the manufacturer's label and
model number on the 'make you squint your eyes to read' printing on the
microphone case you may find it listed in Mouser, Digikey, or other distributors
catalog. I buy direct from the radio manufacturer when possible and also
purchase the rubber dampener at the same time. Being rubber they do break
down and nothing is more aggravating than trying to find a glue that does not
stick you to yourself while trying to coax the torn rubber of the dampener to
stick together.

Please do not use a Weller soldering gun or a soldering iron rated more than
30 watts to desolder the microphone. Do use 'Desoldering Wick' such as
Chemtronics or similar desoldering braid. A substitute is a scrap of coax braid
dipped in liquid flux intended for electronic use. Make sure to determine what
solvent is needed to clean the flux. Many modern fluxes are intended to be
cleaned in a water/saponfier solution and will resist cleaning with many
differing alcohols. If the flux cleans with alcohol buy a box of 'Alcohol Swabs'
like used to clean the skin before a hypodermic injection. You can buy a box
at the pharmacy or Sam's Club in the home medical supplies aisle for less than
about $2.50. Clean the board three or four times with the swabs if used. Don't
use toilet paper soaked in alcohol or paper towel soaked in alcohol. Been
there, done that and cussed for three hours while using tweezers under a
stereo zoom microscope picking out paper fibers that caught misc sharp
points on the tracks and protruding leads.

Displayed below is the typical electret microphone frequency response.
The audio circuitry in the FT-60 will add some pre-emphasis so the flat
curve of the microphone will be altered to produce a positive slope. The
audio chain schematic is shown below if you would like to observe the
audio passband processing used in the FT-60R. If the microphone is
not the problem than there is likely an issue with one of the audio
gain stages that amplifies and filters the microphone audio. My money
is on the microphone.

Whoever told you to remove a membrane should NOT be trusted ...

Check your deviation setting.?

Has your radio been subjected to moisture?

Also, wouldn't removing or puncturing that membrane make the microphone element more prone to plosives? (p-pops, breath noise, etc.)


I talk almost right against, but ACROSS the front of my HT's, and avoid most of that.

I don't think the FT-60 needs it. Where some Yaesu radios seem to have nothing but highs on analog FM, the FT-60 has just enough to be nice and clear.

Re: Restart on UHF PTT

 

I have exactly the same problem, on UHF only (even though radio shows 8.4V after charging). Connected the FT-60's battery contacts (on the radio) to an external DC PS and it worked fine on UHF.
Bought a new original FNB-83 battery, charged it 10 hrs (8.6V after) and installed it last night, radio's been working fine since.
Hope this helps...

Re: Restart on UHF PTT

 

If you have not tried a Full Reset, perhaps the problem radio's microprocessor?has become corrupted somehow.? Seems to happen to my radios from time to time.
Page 64 of the manual spells out the simple procedure.? Absent?that, probably time to consult with Yaesu Tech Support.

Re: Restart on UHF PTT

 

When I worked for a small company repairing test equipment for the telephone industry we got into the habit of automatically replacing batteries because we found out the hard way that the batteries may have plenty of voltage but not the current capacity. That sounds like your problem.

Does the LCD display blink out when you key up? Many newer radios monitor for
low battery voltage and shut down until the voltage comes back up.
