I think the "Plus" for the TM-D700A is that it has the built-in TNC and APRS, which, to my knowledge, the "cheap" Chinese Dual Band mobiles do not have (yet).

I believe I sold mine to a friend for $100 a few years ago. It served me well and was 16 years old or so at the time so I got more than my money’s worth out of it.

But take a look at QRZ and QTH.com to see what recent ones has fetched.

In the appraisal business, that transaction would be an "out-lier" or less than "arms-length" transaction and would be disregarded in arriving at an estimate of value, but thanks for your reply.

I am checking on-line sources for comparisons.

Re: brief intro and a want

Mike Rees
 

Hi Eric,
Unfortunately, the control head for the D700 was never available as a separate unit. The newer D710 does have control heads available. They can be used to convert the V71 to a D710 as well replacement.

The voice module is installed in the main body of the 700 and 710s.  Good news, the volume/squelch control is available from PacParts

I am located in Sun City.  I have a D700 as a backup radio in my go kit.  I will be glad to lend you the control head.  The bad news is I am traveling until the last week in June.  When I return we will get your radio up to snuff.

My name is Eric. The call is n7zzt. I am a blind ham and active in local ham radio activities (or as much as I can do besides also being a blind athlete).

Now, for the want..
I am looking for a replacement control head for this radio, as the current unit has a fault in the VFO-A control. The volume either adjusts poorly, not at all or sometimes on it's own. It also has poor control of the squelch and sometimes won't respond when pressed to go into that VFO/memory bank. This is due to a cracked circuit board at the knob mounting point.

THe unit has a speech module, which I will transfer to the new control head (if I can ever find one) and since I am on a fixed income here, I am hoping to find one cheap (if that is possible).

Anyway, if any of you can help out, I would gladly appreciate the help.

thanks,

Re: brief intro and a want

Eric Oyen
 

well, as I stated, I am a blind ham. So, soldering would be problematic without sighted help. From what I read, the speech chip is supposedly located inside the control head.

I was not aware that the knobs were a "plug-in" sort of item. guess I learn something new (again). :)

anyway, thanks for the info. It should help out locating some of the parts.

THe unit has a speech module, which I will transfer to the new control head (if I can ever find one) and since I am on a fixed income here, I am hoping to find one cheap (if that is possible).

Anyway, if any of you can help out, I would gladly appreciate the help.

brief intro and a want

Eric Oyen
 

Hello all,
I just transitioned over from the ™-D700 yahoo group. It seems that messages are not getting to or from there for some time.

Anyway, a little about me…

My name is Eric. The call is n7zzt. I am a blind ham and active in local ham radio activities (or as much as I can do besides also being a blind athlete).

Now, for the want..
I am looking for a replacement control head for this radio, as the current unit has a fault in the VFO-A control. The volume either adjusts poorly, not at all or sometimes on it's own. It also has poor control of the squelch and sometimes won't respond when pressed to go into that VFO/memory bank. This is due to a cracked circuit board at the knob mounting point.

THe unit has a speech module, which I will transfer to the new control head (if I can ever find one) and since I am on a fixed income here, I am hoping to find one cheap (if that is possible).

Anyway, if any of you can help out, I would gladly appreciate the help.

thanks,

Sorry about the old messages. I saw they were pending approval and just approved them. Normally only new posters require moderation.

" When the filters go bad, they do not start working well again. I am in agreement with your thoughts on the issue being the bad cable."

So with my intermittent behavior, I'm wondering if it is not the filter.  Will mess with it some more, but appreciate other thoughts.

Charlie,

Thanks much for the response. The serial number from the box is B1100050. I'm not sure how to square this with the numerical range you sent.

More testing tonight shows the B side receiving going completely deaf and back intermittently. I switched to the A channel for drive time talking with the locals on the repeater and that works fine. I will do more testing from some of the test tricks I see folks suggesting (change from wide to narrow filter, etc.) and see what I learn.

Thanks again.

TM-D710A Side B goes deaf - requires power cycle

John Huggins
 

All,

A new problem exists in my many years old TM-D710A transceiver. Some information:
  • Band A (left) set to APRS - 144.390 MHz.
  • Band B (right) set to local repeater - 147.165+ with 167.9 Hz tone - memory channel 10.
  • Tone is set to transmit on B side transmit for repeater access.
  • CTCSS is on B side receive.
  • Squelch is down on B side as CTCSS works well.

Occasionally when listening to the repeater the B side simply stops receiving anything. I manually cycle the various tone options and nothing changes. I cycle through memory channels and nothing changes. There is signal shown on the S meter, yet no amount of fumbling yet has re-enabled receive. It seems to happen about once a day. Cycling power with the power button cures it and I don't seem to have a problem any more that day.

I'll add the battery in the display is dead as I have to set the clock manually when I care about it... which is almost never.

Anyone else seen this behavior?  If I cannot figure it out I will purchase a replacement and put this to other uses, but figure it cannot hurt to ask the brain trust here.

Thanks.

All,

Turns out the entire problem is with a bad cable on an external
speaker that was piping the B side to my ears.

One can only hope problems like this are as easily solved.

Thanks for all your ideas.

Thanks everyone. I've sent a message to Kenwood to see about repairs.

So let me ask you all something... Say I wanted to replace just the
transceiver portion and retain the control head. Is the TM-V71A usable with
my original D710 control head as some friends have suggested?
