No travelogue but… SolderSmoke Almanac!

Memorial Day in U.S.

End of Ramadan so Eid Mubarak! 

#222 marks SIX YEARS of Julian-ismo.  He started on SS 161.  Thanks Pete. 

Thanks to all who sent good wishes on Billy's graduation.  He heads to Boston and the lab in a week or so.  Very proud.

PETE'S WORKBENCH

-- Antenna Ideas -- Don't Buy that $165 dollar dipole!  It is just wire!   

-- THE PHASING RIG. Does this point to a need for meditation?  Or at least some temporary disengagement? Tribal wisdom from Pete. 

-- DEAN KK4DAS's rig.  The Furlough 40.  Troubleshoot.  Tribal knowledge.

BILL's WORKBENCH

n  Shortwave dials and exotic locations.  Java!  

n  Galaxy V VFO Project. Series-tuned Colpitts.  

n  DRAKE 2-B.  Hayseed Recap. Put the skirt back on the old rig.  Reduction drives?   

SHOPPING BAG: 

I got a replacement for the Xtronics 4000 soldering station.  Yaogong worked!

Ordered screws and stuff from McMaster -- Came very fast! 

Working on a resistor kit from Mouser. 

MAILBAG: 

VK2BLQ's Phasing RX with an HRO dial.  Cool Retro.  

Adam N0ZIB -- Cool station.  TFT screen Aluminum welded box. FB. 

Karl G7AFT    BITX 40 doing USB and LSB by changing the VFO freq.  Pete's trick! 

Jerry KI4IO  out in nearby Warrenton.   Hope to be able to meet up soon. 

Keith N6ORS's Hot Mustard Phasing Board. 

Mike N5GTF'd FULLY INDOOR Quarantine Receiver.  Need a slogan for the antenna!

Nick M0NTV's Bread Bin 80 Quarantine rig

Bruce KC1FSZ   Quarantine 10 -- Brave man in solar minimum. But I hear 10 is opening.

Talking to Grayson Evans KJ7UM  TA2ZGE about Collins 9.9 MHz transformers.

Talking to Alan Wolke W2AEW about Drake 2-B stuff  Was there a reduction drive?

Paul VK3HN about Ceramic filter spurs.

Peter VK2EMU notes no animals were harmed in the making of my videos.  But many electrons were agitated. 

N6QW Phase Shift Success -- It aint over 'till the fat lady sings

I,Q, and HRO: VK2BLQ's Phasing Receiver with an HRO Dial

I had occasionally fantasized about connecting Armand's HRO dial to the rotary encoder of an Si5351, but I think this was more of a nightmare than a fantasy.   I don't think Stephen VK2BLQ went this far -- I suspect that his HRO dial was connected to an analog VFO.  But still, the combination of HRO with I&Q seems a bit edgy...  FB Stephen.  Please send us more info on this amazing receiver. 

  

Hi Bill,

Hope you are safe there with the bad weather.

Recently you  mentioned HRO dials and the need to build a radio around one and Pete has been discussing phasing SSB; attached photo is a phasing receiver on 80 and 40 m, a combination of both HRO and IQ that I built many years ago, and thanks to Pete I shall get it running again.

And Bill, like you I am from the IGY of 1958 and retired with more free time on my hands.

Best regards to you and your family, especially young Billy.

Stephen,

VK2BLQ

Replacing Electrolytic Caps in my Drake 2-B (Video)

Every dark cloud has a silver lining. Here is a very small silver lining for this terrible COVID-19 situation:  I had time to do a proper replacement of the electrolytic capacitors in my Drake 2-B. 

Three cheers for Hayseed Hamfest LLC for providing the replacement capacitor.  
Go to their website to find capacitors for many other old rigs:

SolderSmoke on Ham Radio Workbench Podcast

It was great fun talking to George and Jeremy of the Ham Radio Workbench Podcast last week.  You can listen to the episode here:

Thanks to George and Jeremy.  

Homebrew Az-El Satellite Antennas from the Philippines and Australia

https://nightskyinfocus.com/2020/05/18/diy-satellite-tracker/

DU1AU is way ahead of where I was when I was working with Low Earth Orbit satellites.   I just aimed the antenna about 45 degrees up from the horizon,  and spun it around with a TV rotator with me --not the computer -- as the controllers of the rotator.  In essence I did the AZ manually and completely ignored the EL.  This design moves the antenna in Azimuth and Elevation, and has the computer control the movements via an Arduino.  FB. 

DU1AU points to the work of VK3FOWL and VK3YSP.   Their site has very detailed info on how to build several versions of this kind of Az-El rotator: 

https://www.sarcnet.org/rotator-mk1.html

This Az-El project represents a great opportunity to move beyond hand-held satellite antennas,  and beyond my Az-only manual approach.   It also give us a way to bring some real homebrewing into a part of ham radio that has come to be dominated by commercial equipment. There are some Arduinos and some lines of code, some motors and some metal work.  Great stuff!
