Topband: DXE NCC-1 phasing box

[Rob Atkinson]

Hello,

I am trying to set up a DX Engineering receiving antenna phasing box
but there appears to be something wrong with it and I need to
troubleshoot it.  The manual I have does not have a schematic for it.
If anyone has one I'd appreciate getting a copy.  I'll cover postage
etc.

Thanks 73

Topband: Boring Report (from Hillsboro)

[Tree]

I am happy to report that after several years of not hearing a peep from
Europe - G4ERZ was coming through last night.  This is a very positive sign
that conditions on 160 meters are starting to to recover from the sunspot
peak.  His signal appeared to have long QSB - but was "arm chair" copy on
his best peaks.

Antenna system has changed as I am now at a new QTH.  Using a Hi-Z array
with 4 verticals spaced 80 feet apart.  Transmit antenna is a loaded tower
with about 25 radials.  Will probably go add another dozen radials soon
just to make things as good as possible.  In December - I will hopefully be
able to put up my Eastern beverage (1200 feet) again like I did last year
when the farmers are done working the field.

This morning - several JAs have been heard along with a QSO with V633ZH.

Topband: DXE NCC-1 phasing box

[Rob Atkinson]

update:  I just received an email, perhaps a canned response from DX
Engineering telling me they won't give me a schematic.  In addition,
rather than work with me to find the problem, they only offer their
repair service.   I am very disappointed in this after spending over
$1000 over the past two years on the Pro-1B loop antennas.  I guess
this means no one has a schematic so I'll just have to signal trace.
If this is a business decision, I think it is a poor one.
It certainly gives one pause about future purchases.

Rob,

I just looked at my NCC-1 manual.  No schematic.
It seems odd they wont provide one. I wonder what their
reason is ?  I would give them a call.
I may call them myself, I am contemplating the purchase of the
new model but would like a schematic

I just finished speaking with Tim K3LR on the land line with regard to
my problem  We had a cordial conversation and I must say in all the
years I have been a ham, I have never had the president of a company
immediately call me to address my concerns and problems with a
product.   I am confident whatever is plaguing my NCC-1 will get fixed
whether it's the unit, or operator head-space.

I also received a satisfactory explanation for the policy of not
providing a schematic for the NCC-1.   The repair service terms as
explained to me are quite reasonable but I hope I don't have to send
it in for repair.  I certainly appreciate this fast response.   Also,
I mischaracterized the service dept. email as "canned."  It did have
some personalized text in it which I overlooked and I apologize for
that.

Because it's considered propriety information. You paid for a black box that 
does what it says it will. You did not pay for the why or how it works. This 
is not unusual business practice. You bought a car with dozens of black 
boxes in it, do you have schematics to those?

[Jim Garland]

Tim is an outstanding ham and a super nice guy, but he unfortunately
inherited the "no schematic" DXE policy when he took his job. He does his
best to provide customer support, which I appreciate, but there's not much
he can do about changing the policy, which customers have complained about
for years. Fortunately, most of the DXE products are quite straightforward
and easy to reverse engineer. I did that myself, with my beverage switching
unit, which failed almost immediately. I took the cover off, found an
electrolytic capacitor installed backwards, and fixed the problem in five
minutes. On the plus side, I've found DXE products to be well-designed and
solidly built. To me, the lack of technical service information is
frustrating and misguided, but not a deal-breaker.

Re: Topband: DXE NCC-1 phasing box

[kolson]

I hope hams are not becoming strictly black box users. I also hope that there 
isn't a parallel being made between a licensed ham buying a piece of amateur 
equipment and some dude buying a Smartphone. 

In almost any technical environment, having info on how the product works and 
troubleshooting info isn't just some frivolous luxury. At my job, not being 
supplied tech info is a significant argument for not buying the product. For my 
ham activities , h aving info on what's in my radio  is actually something that 
I as the buyer expect. In either case, I find being told "you just have to send 
it back" whenever there is any problem unacceptable. 

Of course, the business in question can run their affairs however they want. 
But so can the customer. I had to laugh, when a customer (who was not 
particularly patient) brought in one vendor's vacuum tube preamplifier for 
repair, I asked the manufacturer for a schematic to make things easier. He was 
a real nice guy, but replied that the info was proprietary. I responded that 
there were only so many ways to hook up triodes! He still demurred, so I drew 
out the schematic from the circuit board and sent him a copy  just for fun! 

And actually, I drive a Prius and there are schematics and troubleshooting info 
available for it...

Re: Topband: DXE NCC-1 phasing box

[Herbert Schoenbohm]

I recently replace my MFJ RX antenna phasing units with a DX Engineering 
NCC-1 and find it well worth the money There is a vast improvement in 
the phasing controls instead of MFJ's tiny knobs. they give full 
rotation and a phase reversal switch on either antenna which can be 
employed instantly .  By using two Beverages that are either pointed in 
the same or opposite directions I can enhance the forward reception, 
null out IX fro a close by local station better, or improve the F/B in 
the desired direction.  I use BC stations in PR and down the Caribbean 
to demonstrate to myself that the the NCC-1 is a phasing properly.  
Nulls are deeper and I can move them around as desired.   The 
construction of the unit is excellent. Yes it would be nice to have a 
schematic but i can understand how this could be outsourced overseas 
quickly and to the determent of the designers  I like the fact that 
DX-Engineering is standing by their products  And that is good enough 
for me.


I remember and old indisputable adage"That which works 
bestworks."  Who can argue with that?

Re: Topband: DXE NCC-1 phasing box

Oh, a time ago I considered to buy the NCC-1. My final "NO" decision was caused 
by the "no schematic" policy or "Proprietary information" balast (also know as 
a Trade Secret). I will never buy such product although there are many. I 
believe that such "Trade Secret" can put both the seller and the designer (ie. 
the "secret" owner) into disreputation.

Topband: No Schematic Policy

[Tree]

This is a blatant attempt to keep this thread from getting too far out of
hand - and at the same time - interject my own personal view about the "no
schematic" policy.  :-)

I certainly can understand those who would be reluctant to purchase a piece
of equipment that did not include a schematic - so they could repair it
themselves - or even perhaps make modifications to better suit their own
needs.

However, I can also understand how a company - who might have paid a
consultant (someone like W8JI) something like $3,000 for that very same
schematic - might not be willing to put a copy of it in every unit they
sell.  DXE is running a business - trying to make a profit - and I see this
as a reasonable position to take in order to protect their investment.
Certainly - they recognize that some portion of the market will not accept
this decision - but they have decided to proceed in that direction.

You - as the consumer - can make the decision about which direction you
would like to go.  However, the likely reaction to poor sales for products
that are made for "topbanders" is that there will be fewer investments made
in future products that serve the same marketplace.

And now - for the attempt to put some ice on this thread - I think we have
hashed this out and both sides of the issue have had their say.  Time to
hopefully put this issue to bed and focus on the good conditions.  Thanks.

Re: Topband: DXE NCC-1 phasing box

[Herbert Schoenbohm]

Martin, its all about reputation and DX-Engineering has the best.  Back 
in the 80's some periodicals were marketing the MaxCom baluns which 
claimed that they would yield a 1.5 to 1 SWR from 1.8 to 30 Mhz but 
refused to provide the details in schematic form. Many hams bought into 
this scam and QST refused to run their ads. What HQ did was take an 
X-ray of the unit and found inside some toaster heater wires sealed with 
epoxy resin. All it turn out to be was a dummy load with wires attached 
to the balun.  Anyone with knowledge would have known that the MaxCom 
balun was junk even though the SWR response was, as they advertised, 
relatively flat across the spectrum.  So your point is well taken except 
that the reputation of DX-Engineering should remove all doubt that you 
are buying a good product from  them.

Topband: RESOLVED: Help needed with RTR-1A

[Mark Lunday]

Thanks to the 15 or so hams who contacted me offline to assist with this
issue.  The resolution:

 

1.   The RTR-1A units are working fine (no surprise there)

2.   It is NOT operator error (BIG surprise there)

 

After some more research on different message boards, and a great discussion
with Rod at DX Engineering, I learned that the TS480SAT 8-pin mini DIN
connector ground does NOT connect to chasis ground!  Therefore, the RTR-1A
won't function as I was trying to set it up.

 

Thanks to Dan, YO3IRM, I was able to get the unit hooked up and working
perfectly.   

 

For any other hams using a TS480SAT, see the attached GIF for how this was
resolved.

with my Flex 3000 before I sold that rig.  Now I am trying to use it with my
TS-480SAT.

I actually have TWO identical units.  Both are exhibiting the same behavior:
without even connecting the RCA ground plug, I cannot get the units to
switch between receive antenna and transmit antenna using the toggle on the
front of the unit.  (I think that's how I accidentally ordered the second
unit 6 years ago, I thought the first one had an issue after moving my
shack, but somehow I hooked everything up and it worked fine).

I can receive RF from the transmit antenna jack through the RTR-1A to the
TS480.  This is the default behavior with power off.  With the power on, I
see the same behavior for both units, and regardless of the toggle setting
on the right hand side (RX ANT or MAIN ON).

Topband: Delaware report

[Jon Zaimes]

Friday morning at 1041z, about 10 minutes before sunrise, JA9FHB called in
for our first JA QSO of the season. Another JA9 called right after but
unfortunately we did not complete that QSO.

 

Nice to hear the band alive!

Re: Topband: DXE NCC-1 phasing box

[Greg - ZL3IX]

Hi guys,

I hope you will forgive me for adding to a thread that the moderator has 
requested be shut down, but all the traffic on this happened around 2 AM 
while I was in bed.


My own view is that anyone intending to make a business in the field of 
amateur radio needs to understand the domain and the ethos. In our case 
part of our 'excuse' for having our licences is that we are carrying out 
self training in the field of communication. Refusing to supply a 
schematic for a piece of kit that is intended for ham radio use,  is 
contrary to ham spirit, in my opinion.


About a decade ago I designed my own 8-circle system. It was slightly 
different from the DXE version, in that only four of the elements were 
active at any one time. The four chosen were the ones giving a 
broadside-endfire configuration in the desired direction. I published my 
design in the national journal in NZ, and one of the guys in G-land with 
a website kindly put the article on his site for all to see (thanks 
John). In the event that anyone would have wanted to manufacture such a 
system for sale, I would have allowed this, but I would have insisted 
that they publish the schematic.


There are those who design and build their own kit, those for whom it is 
too complex and prefer to buy ready-made (this group is the main source 
of income for the equipment manufacturers), and those in the middle who 
will buy kit and modify it. Maybe someone in this last group will have a 
good idea for an improvement and advance the art by doing so. Power to 
their arm, and please give them the schematic to help them on their way.


I have an excellent amplifier from SPE in Italy, and I have had the same 
argument with SPE. Now, how many hams are going to copy the schematic 
and make their own SPE amp? Any other organisation wishing to copy the 
SPE design and reproduce it for profit, will reverse engineer it without 
the schematic being available. SPE needs to understand the domain in 
which they choose to engage in business and respect its ethos, and so 
does DXE.

Hello,

I am trying to set up a DX Engineering receiving antenna phasing box
but there appears to be something wrong with it and I need to
troubleshoot it.  The manual I have does not have a schematic for it.
If anyone has one I'd appreciate getting a copy.  I'll cover postage
etc.

Thanks 73
