I bought a package of 10 SO-239 chassis connectors on eBay at a great price. Â The connectors looked good, teflon insulation, gold plated pins. Â However it was not possible to thread a PL-259 male connector on more than 2 or 3 turns.
I then understood why the price was so low. Â I decided that the solution was to re-thread the connectors. Â I looked for a die at local tool stores but no luck – Â I was told that 5/8-24Â was a thread used in electrical connectors but not commonly used by machinists. Â Checking on Amazon it became clear that the proper die was available at reasonable cost as a “gunsmiths” die.
As soon as it arrived I tried it. Â I did not have a holder for this size die so I used a “Quick-clamp” with rubber pads. Â I used lots of cutting oil and took my time cutting the threads. Â The result was a bare brass thread which easily took the Amphenol PL-259 connector.
I don’t know if the manufacturer in China used a 16 mm die in place of 5/8″ or if they failed to take the thickness of the nickle plating into account when cutting threads. Â Whatever the reason now I have the tool to make it right!
The photos tell the story. Â 73 and keep on building. Â Earl VA6TJ

Remote tuners are offered by MFJ, LDG and others. Here is my brief review of the LDG RT-100 tuner.
I purchased the tuner new, at what I considered was a competitive price. As you can see from the photo I am using it to tune a horizontal loop antenna close to the feed-point.  The tuner is matching a short section of low loss open wire line and not a long section of coax.  The tuner requires 12V DC at low current so I powered it from a gel cell battery and a small solar trickle charger panel (CND$14). This remote solar power arrangement has been in operation for several months now without issue.
The tuner finds a match from 80 – 10 meters on the random length loop (~130m of #10 multi-strand insulated wire, 10m high).
I have found a few issues with tuning; i.e. failing to find a good match on a band or frequency. As per the instruction manual a tune can be “forced†by changing bands, re-tuning and then returning to the frequency you want to operate on.
The second issue noted is a de-tune with changing weather / moisture conditions. For example rain or heavy dew on the antenna may cause the antenna to re-tune. This does not often happen but it is inconvenient there is a re-tune cycle in the middle of a QSO.
I experimented with different baluns and found that a 4:1 air core balun worked best for me. This balun is very easy and inexpensive to make using parts from the hardware store.   The antenna is maintained at DC ground through the balun and tuner. (Yes, the ground wire should have been green…major fail !)
Using the remote tuner I was able to operate on SSB effectively on multiple bands with a single wire antenna using only 100 W. The loop antenna was found to be very quiet as a receive antenna. On 20m a signal barely audible on a dipole was perfectly Q5 on the loop antenna.
So if your opportunities for erecting antennas are restricted my experience shows that a multi band wire antenna with a remote tuner and one feedline can be an effective way to operate HF.

The 45th Anniversary Red Deer Picnic and Hamfest was a huge success. There were 112 people registered.  On Saturday morning Radio World and other flea market vendors enjoyed selling new and used radios and accessories under a beautiful and sunny sky. Greg and Karen and Karen’s parents began the process of roasting of the pig at 3:00 AM! Thanks for your generous donation of the pig and all your time!  Everyone enjoyed the roasted pork and the pot luck dinner Saturday evening.  Following the meal we watched the 45th anniversary video produced by Vance VA6VAN. Thank you Vance, for editing the pictures and videos sent from numerous hams. The weather was great Sunday morning for the pancake breakfast, egg toss and the  draw prizes.
There were many people who helped in various ways to make our 45th anniversary hamfest and picnic a resounding success. A special thank you to Phyllis and the ladies from the 160 gang from Camrose for organizing the fun craft again this year! Â Thank you everyone!
