Rick's question about the availability of a clamshell battery holder for the FT-60R radio raises some potentially helpful points for the original poster. Yes, Yaesu makes a 6 cell AA battery holder for the FT-60R HT and it is highly recommended among many, if not most, ARES groups to have one for your radio. AA cells are used in a multitude of emergency HT radios when a major incident is ongoing and their availability is usually very high. I would recommend the original poster get the clamshell battery holder and carry a stash of AA cells too. Their shelf life is good for many years. OR, if one is absolutely fixed on the idea of being able to solar charge the communications battery, one could purchase NiMH rechargable AAs and use a readily available 12V charger circuit in conjunction with a solar panel to charge them. It would probably work somewhat better with the original poster's 3W solar panel than his initial idea, but still 3W solar is really far too little. Best to stick with AAs.

I would be very cautious about using padding of any sort on the bottom of a mag mount. Other than a very thin piece of plastic, it does not take much to significantly reduce the holding power of a mag mount, and even though HF antenna mag mounts are much stronger, so is the torque applied to that mount by HF antennas.

After reviewing the only pictures I could find of the original poster's car I see that his hatchback does NOT have a trunk of any sort, so the comments I made above would not apply unless he wants to use it on the hood lip....which would work well too. For an antenna mount for the hatch back rear I can only suggest that Diamond makes a very complete series of antenna mounts just for such vehicles and I am certain that one of the extensive model line mounts would work well for this car. Unfortunately he would need to do his own research as to which would work best. It would be best to have an actual product in hand to view as every hatchback has a bit different construction and design.

Your URL Link did not work for me but I went to the web for a picture of the rear of your car. It looked to me like it had a tiny trunk. If so, and assuming you are just looking for a basic 2M antenna, I'd highly recommend a small trunk lip mount such as available from Antenex, their model TM8 ( ~$30) or if you want black, the TMB8 ($38.) . It is very small profile....about as tiny a mount as you can get, is no holes mount on the lip of your trunk edge, and takes any NMO type antenna base. I'd also recommend you get a nice 2M whip made by St-co, their flexi-whip which is also about $30. It is ultra thin and flexible....low profile visibility and won't hurt anything if you bump into it as it is so flexible like the ones available for HTs too.

eHam Forums / Station Building / RE: Crimp Solder PL259 - Where do you buy your connectors?
|

I can find crimp crimp but I want crimp solder (center).... It seems tough to find any at a decent price (HRO is outrageous in pice compared to the manufacturer price).
What brand do you use and where do you buy them?
Thanks
You did not specify what type coax you want a connector for. Amphenol probably makes what you want. Their 83-58SP will work on RG-58 coax, their 83-59SP should work on RG-8X, and the 83-8SP-RFX is for RG-8 coax. Google the appropriate part you need for source and price. Mouser, for instance, has the RG-8 size at about $3.00 each for orders less than 10. Note: the Mouser sample picture does not show the actual part.... crimp base, solder center, that you want but the part numbers I gave above are accurate. Ed K7AAT

I want to concur with what WX7G said. Heed his words. The only additional comment I would make is that in my view your 40W iron is just a wee tad light on wattage for general good soldering like this. To ensure a good solder flow, once you see solder begin to melt..... cease adding solder for several seconds... just let the joint get hotter .... then begin to slowly add the solder again. You want to ensure good hot connection so the solder melts fully and flows before it begins to cool off. If you were working on a PC board I might offer different advice to protect overheat damage to the board and components, but in this case you have nothing to damage from heat.... you just want good solder flow. Good luck.

As others here tried to tell you, you'd have been better off replacing the 5/8 antenna on the roof with a 1/4 wave whip. Moving any antenna to a less effective ground plane is only going to give you inferior performance. If your budget allows, I'd also suggest a Sti-Co super-flexibile whip . You will not have to worry about obstruction damage to your antenna anymore; but even a non-flexibile 1/4 whip would be preferable to what you have done.

Ordered MixW SW from the link on their website. Credit Card charged immediately, and promised that the license key would be sent directly from the author (UT2UZ) within 48 hours. Never sent Chris K4CKB
I would suggest you contact your Credit Card company and report this. They may want to conduct their own investigation but I suspect they will reverse the charge for you. Ed K7AAT

Unless I missed it, not a single response has been seen so far that mentioned using a remote tuner. You could put up almost any kind of antenna you want; a low loop around the perimeter of your lot, a loop around the perimeter of your house, a short vertical on your roof, taller vertical on the ground in your back yard, and you have a variety of locations you could string a resonant or non-resonant dipole antenna. You do not need expensive verticals that only allow decent SWR in small portions of the HF bands, and you don't need fancy dipoles with traps or specially configured feed lines to make them operate on multiple bands. All you need is a remote tuner and your imagination to put up whatever type antenna suits you and works best for you.
