Re: Ozark Patrol Tuning adjustment question

Jerome Wysocki
 

Hi Curt,

The most likely thing to do, I think, is to replace (change the value) of c11, a 560 pF capacitor, that is wired to the toggle switch, that is your band switch. I believe with the 560 pF capacitor switched in the circuit, to parallel it to c1 (the 365 pF variable tuning capacitor) you are on the higher frequency band, and when c11 is not in parallel with c1, you are tuning the lower frequency band. (I hope my logic isn't reversed here.)

I also found that increasing the battery voltage from 9 to 15 volts, the tuning ranges changed noticeably on both bands. That might be another option to experiment with. (15 volts also gives much higher audio to the speaker.)

How is your regeneration control doing? Mine was very unstable on both bands until I inserted a 10 ohm resistor in series with the one turn (feedback) loop that goes to the center of the torroid coil ring. (I've built a number of regenerative receivers before, so am familiar with good ones and unstable ones.) I connected the resistor to the one turn loop, on the side that was outside the center of the torroid coil. That vastly improved the stability of the regeneration control. Encouraged by this, I will fine tune the resistor value to see if I can get even smoother regeneration. (Greater that 10 ohms, and I lose all regeneration, but I might get better stability with, say 8 ohms. I will have to try this.)

How does the performance on the two bands of your receiver compare? Mine is now very stable and useable for cw and ssb on 80 meters, but no luck yet on the top band, for 40 meters.

Hope this helps you out.

... Jerry Wysocki, KC9JXE


qrparci reflector at groups.io

Jim Stafford W4QO
 

Still plenty of openings for the qrparci reflector.
450 members so far.  Lots of contest chit chat.
You may/should advertise your QRP contests
and/or activities on this club reflector.
 
For example, check out the posts to the recent SPRING
QSO PARTY event:  qrpcontest.org with over 60 entries.
 
Click on SPRING QSO PARTY…  
It all happened due to huge publicity on the qrparci
reflector: qrparci.groups.io  Take a look; the posts
or open to read and easily searchable.
 
You do not have to be a club member to join this reflector but
if you are a member of qrparci, this is your
club’s reflector.  Ask questions, get latest news, when
QQ ships, etc.
 
If your email address does not include your callsign…
the also send your callsign to cw at w4qo.com
 
qrparci.groups.io    Then hit the SUBSCRIBE button.
 
Have you checked out the RBN skimmer for
members of various CW clubs:
http://rbn.telegraphy.de/  Good way to spot
SKCC, CW OPS, QRPARCI, etc.  To see your
callsign, just call CQ or send TEST followed by
your callsign.  This assumes you belong to one
of the clubs listed.
 
NOTE: this is not trying to take traffic away
from QRP-L or any other reflector.  With so
many sitting inside these days, plenty of time to
read lots of ham radio news…. 
 
And check out the FL QSO PARTY this weekend:
QRP category!  Lots of stations on the air from FLA...
 
 
Take care.

Ozark Patrol Tuning adjustment question

Curt
 

Can anyone advise about adjusting the Ozark Patrol tuning range?  On the top band, mine covers 4.6-16.2 MHz, a range of 11.6.  The marked dial is 5-12 or a range of 7.
On the bottom band it covers 3.3 - 4.5 range of 1.2, marked range 3-5 range of 2  So the range is small on the lower band but wide on the upper band.

The radio functions fine as it stands, but would like to get it set closer to the dial.  I am wondering if adjusting the pad/trim trimmers on the variable capacitor would provide some improvement? 

Suggestions?

Curt KB5JO

Thanks for the info Charles.

Has the quality of the parts been improved?  I recall connectors that
had insulation that looked like Teflon but when soldered would melt like
cheap PVC.

Well
That didn't work too well? 
I heard sigs on 3875 about 8:30 and by 9:30 they were gone. 
Bert and I are about 40 miles apart and you could just hear something on 3.730, not enough to copy. 

We can try again late this evening, signals might be better?
Say around 8:00 pm CDST?

I am in New England and it seems that as the morning goes on, the signals get weaker and the noise gets louder.

Don’ know but......  I think I might do better if we try QRP AM in the PM.

Probably the 3.730 - 3.740 region would be a good area to try.

What do you all, (especially near me!) think would be a good time?

Got a barefoot Nouveau 75A running off 13.8v to an end fed half wave to a bush to a tree, not exactly straight to a couple of not too tall trees. Probably about 30G stranded wire picked up from a ham fest.
 I use WebSDR on line as a sort of pan adapter to spot AM carriers but the nearest station they have that I can listen to/watch is in Pennsylvania. Earlier this morning I could see my carrier really faintly (but hear nothing) and now at 9am can see nothing at all there, coming from my station.

We've a Radio Shack in our smaller town of Emporia, KS.  Opened fairly recently.  The proprietor told me that all of the RS now operating or opening are independent franchise stores.  He indicated that RS corporate would continue to supply inventory for a long time.

... hmmm, "not supplying their warehouses anymore"? If true, that's a bad sign for them, like going out of business, once and for all, end of enterprise. First, stores gone, then warehouses?

Try this link:

I have been buying things from RS on line for some months now. 

They sometimes have good deals, but they are still RS quality.

In addition, they are running out of stock and they are not replenishing their warehouse any more.

What is gone, is gone forever.

Stay healthy,

I had an immediate need, and with amazon slowing down shipment of non-essential items... I ended up going to eBay and paying a little more for shipping - BUT getting things here in a week vs 2-3 weeks.

Hello,
      You should be able to get a modest amount in a tube down at the local hardware, or home Depot/Lowe's type store for repairs to pipe. Much smaller container should be readily available, and cheap.

Have been unable to locate small squeeze tubes or small containers of this type on-line so far. Did find some suitable, but a $50.00 min order  OR canisters running in excess of $100.00.
