LD5 transceiver

Scott WZØW
 

Hi all,
Does anyone else in the group have any experience with the LD5 xcvr from LNR Precision? I've had one for about three years, and I can't quite get the CW keyer to work well. It skips dits and dahs frequently and I have to work my paddles pretty hard to keep that behavior to a minimum. It also works a little better if I run it at full power, but then it reports a power output of about 8 watts, so a bit outside the QRP limits.

If anyone had used this rig and has any tips for making it work better on CW, I'd appreciate it. Aside from this issue, it's a handy little 5 band, all mode unit that could be great for portable operation.

5 Feb. 2020 would be better.
1600z. 7032.


After the Winter FD Ops at Ice Station Zebra,
Don, AA6GA, told me that i was not responding to some calls on 7032 kHz.
i checked my BC-221 and found that my transmit frequency was 400Hz lower than my receive frequency. So the only guys i worked were those who didn't zero beat me.
i was not 'transceiving', i was working 'split'.
The base transceiver i am using in my Re-Purposed BC-221 is the '1 Watter'.

i checked out the 1 Watter and found that the 10V regulator (U1, 78L10) on the VXO was not regulating well enough. i tried 3 different 78L10's but they were all inadequate to regulate the 10v line. My 12V battery was dropping down too close to the top requirement of the 10V regulator.
So i replaced U1 with a LM2940T-10, 1A, 10V, Low Drop Out regulator in a TO-220 package.
It also has a 22MF capacitor on the output.
The LDO regulator will keep working as my battery discharges.
(ps: My 'Tune' pot is 50K ohms).
Now  my RX freq is the same as my TX freq. My 10V line is steady now.
i will be back on the air with the BC-221 again testing it on   5 Feb.  2020, 1600z, 7032 kHz.
So if you called me and i didn't answer, here is your chance to get your special "Dino" QSL card.

PAUL,

That is a great looking project, love this part of the hobby maybe even more than piling up QSOs !  Having a problem and fixing it is almost as rewarding as the completed project.

I assume that you plan to be back on the air with the rig on FEBRUARY 5 ?

I ‘ll give a listen down here in Florida.

PERIODIC REMINDER

The 4SQRP Mailing List exists for several purposes:

  • To encourage the discussion of QRP activities and techniques, especially those that relate to 4SQRP events.
  • To provide support for 4SQRP kits and products on the main list or in one of the specialty subgroups.
  • To share your QRP operating experiences and techniques.
The 4SQRP Mailing list IS NOT for the purpose of supporting the products of other companies or clubs. If you have a question about their products or if you have a service issue with another vendor, this is not the place to discuss it. Contact them directly. We're sorry you had a problem but we aren't here to help everyone in the world.

If you choose to ignore our simple rules don't be surprised if you receive a note from a moderator, get yourself placed on permanent moderation, or get banned from the list. We are all reasonable people and are not vindictive. However, we can be provoked. The Moderators are volunteers. We get no pay, no free kits, etc.

One last comment; Sending a message outside the guidelines but marking it as "off topic" is sure fire way to get placed on moderation as you have clearly demonstrated that you don't believe the rules apply to you.

Although it is true that tuning a loop antenna while transmitting is bad for your help, it is also true that you may very well be able to tune the antenna in reception mode by listening to the noise coming from the speaker: the higher the noise level becomes the closer to the receiving frequency the antenna is.
I saw a modification for a loop antenna that used two pieces of garden hose set around the knobs that seemed to work despite of being cumbersome to setup.

Re: Portable Battery Recommendations

John Lonigro
 

Don:

Not designed as a QRP radio, your IC-706 draws as much current on receive as many QRP radios do on transmit.  Another important factor is the display backlight.  Measure the current with the backlight turned on and then turned off and you will see that a lot of battery life is consumed lighting the display, not operating the radio.

Based on what I'm seeing here about battery life it's time for me to get some new batteries.  I have only done 2 portable operations in the past few years with my Hilltopper 20 and Black and Decker battery.  When I did more portable work a 7.5 amp hour gel cell would only run my IC-706 set to its lowest power setting for about 90 minutes of typical operating. My 20 amp hour gel cell would go about 4 hours. 
Looks like it's time to go shopping for lithium batteries and maybe a more efficient radio.

For an Argonaut IV or KX2, a 30Ah battery will last a couple of weeks!  For an afternoon's operating, see what other folks who are running QRP on this thread have mentioned.  I have an old Hawker Cyclon cell (4Ah) and a couple of newish SLA (4.5Ah), and in my busiest SOTA operating day I have never drained them enough for the power to cut back on my KX3, running 5-10W.

The other consideration with large lithium batteries is that they're
potentially (!) a bomb. I'd be pretty careful about transporting and using
them so as not to damage them and cause an explosion/fire. Then there's
expense.
Because of this, I avoid lithium ion batteries. When I do use them, I
only charge them while I am around, and I have careful to avoid
mechanical damage. I would not want to use polymer cells without full
mechanical protection. I have heard many horror stories about lithium
ion batteries and fires.

Lithium iron phosphase (LiFePO4) is a different chemistry and is far
safer. I have not heard about these being implicated in
fires/explosions.

I have two Bioenno LiFePO4 batteries, and they have behaved well. They
have an internal controller for balancing and overcharge/overdischarge
protection.
