As you can clearly hear, the repeater has been taken down for repairs / mods and whatever it takes to make it sing the happy song we all expect again. Be patient, this is volunteer work! I’ll update here as things progress.

As told in last nights Tech Net, the repeater is DOWN until the new antenna is installed at the new tower. I’m told there is a possibility for the antenna to be installed today, but remember we are less than secondary in their priorities so be patient. Shortly after the antenna is confirmed installed, the repeater will be put in place and on the air.

Expect some differences in coverages and possibly some glitches until it’s settled in.

I’ll update here as news arrives. Until then, we can use the 147.015 repeater as long as we follow normal repeater protocol. Chill, we’ll be able to play ‘120 style’ when we get back on our own box. For now, just consider yourself a GUEST in someone else’s living room and behave yourself accordingly ;]

We may be off to a late start but we’ve managed to get the City of Montverde to allow us to use property they own at the TOP of the hill on (Lake co.) CR455 overlooking Lake Apopka. Here’s a link to a map, check it frequently as we make plans I’ll draw it on the map.

Please reference the WIKI to post equipment you can bring or any other plans / items you feel appropriate –

Of course the discussion can happen on the air on the repeater! I’d just appreciate if once planned, it gets noted on the WIKI so everyone can see what’s going on.

We’re making plans for a porta-pottie, but everything and I mean EVERYTHING else is up to you guys! I was thinking it would be great to have a cookout; we’re approved for an open pit fire. Covered dish? Cool beans! Maybe literally hihi.

Tents, tables, generators, water coolers, ice, just things to mention. If we want shade, we gotta make it. There’s usually a breeze up there but it gets quite still in the night and off the shore of the lake there will probably be lots of mosquitos, so some strong fans and deep woods off should be in the plans as well ;]

The whole city will probably stop by to see what’s up; everyone knows that’s city property and will know the event is publicly accesible so they will just stop in as they desire.

Put on your ambassador hat and come play at field day!

Go to the 147120_projects Yahoo group to discuss thebest time and day for the return of the central Florida Tech Party. Vern, KI4SDY proposes the return of the Tech Party to Longwood – Join in the discussion and lets get this party started!

Here are the bandcharts I always talk about. This is a collection of several different ones, including ARRL, Icom, W1CGS, and myself.

Hellraiser Transmitter Project - Photo by Hans Summers

Hello again. I would like to share another resource that will inspire, inform, and astound. Hans Summers, G0UPL, is an Electronic Wizard of the Twelfth Degree (see the International Brotherhood of Electronic Wizards Handbook for further information). He has built a website that abounds with inspiration. His projects are visual and functional. He likes to use tubes and will spurn convention to create a visually appealing project. This is art. The amount of information is sure to keep you busy and should be bookmarked for reference.  I am interested in his extensive information on Huff and Puff Oscillator stabilizers and identifying crystal parameters. He builds his own test equipment and documents so that we can follow in his path. Several QRSS projects are detailed. I have added QRSS to my list of future projects. Thank you Hans, for sharing a lifetime of experience at HansSummers.com. 73

G QRP Club

Resources abound on the Internet. The G-QRP Club located in England is one that I enjoy. If you “click” on their logo above it will take you to the site. They have data sheets with excellent  information for the beginner to the advanced builder. The Club magazine, SPRAT, is published quarterly and is full of inspiration. I just received the fall edition and found an article on Weak Signal Propagation Reporting, WSPR for short. There are plans for The SixBox, a very simple 6m AM transceiver. The G-QRP Club is devoted to low power communication. Membership is $15 a year and you will receive four issues of SPRAT.  73

NORCAL S9

NORCAL S9

When I started planning the Hendricks BitX20a Project there were several pieces of test equipment that I found would help. One of the needed items was a signal generator. NorCal QRP Club makes a fine kit with easy to follow directions for those such as I, i.e. directionally handicapped. It has four crystal controlled frequencies. I needed 11Mhz so a quick trip to Sky Craft (that was a joke) supplied a crystal that was exchanged for the supplied 10Mhz crystal.  The S9 kit is a mix of surface mount and through-hole construction. It also has an attenuator that drops the signal to an S1 level. I am guessing  this could be helpful when adjusting the receive end filters. Upon completion I found the signal to be very weak and when I switched in the attenuator the signal disappeared. I took it to my Elmer, K4DF, and he described the circuit to me as we hooked it into his HF rig. When he finished showing me the oscillator and attenuation circuits he suggested I check the solder joints in the oscillator section. A magnifying glass and some quick soldersmoking solved the problem. This kit will fit in a Altoids tin, but I do like looking at it. These kits are great fun and provide practice with an iron. Soldersmoking rules. 73

Bitx20A Alignment in Progess

Bitx20A Alignment in Progess

Hello, I have been graciously allowed to post some thoughts about my ongoing relationship with a Bitx20A.

Where to begin… my name is Robin and I am a homebrewer. It all began when I found out you could build your own and learn about how a radio really works. No more black boxes with multiple-multifunction knobs and buttons for me. I was completely innocent, without a clue of the power this would have over me. Before I knew it I was a frequent-flyer at SkyCraft. Late night sessions at the dining room table with smoke wafting about as I ponder the perplexities of mixed oscillator signals filtered through polycrystalline mineral wafers. I still remember the joy of hearing the audible oscillations of my first Colpitts, but I digress. Consider the consequences, it is not for the faint of heart. If this is the path you choose, know what lies ahead. Capacitors that disintegrate before your eyes, signals that disappear after just a small tweak, and the frustration of “dang, I followed the directions and it don’t work”. I warned you!

That said, I will post a few photos and discuss my Bitx20 from time to time. I want to thank Tracy for his inspiration on the Tech Net and David for his Web expertise that allows me to be here. 73

My first HAM radio project! There is nothing like something new. I don’t know what it is but it gets you excited. My first radio was just that. The brand new Yaesu VX-8. I bought it on valentines day at the Orlando HamCation. Bad timing… My valentine was laughing at me for taking my radio to bed with me!

Brand new HAM. Hello to all. Looking forward to many years of “new” in this hobby. I’m hard at work on my next project. Will post again soon. Please comment on the audio stream project…
