Re: Loosening tight screws
Where can I find the size of the screws on the rig so that I can buy the right screwdriver? There are retailers in ?ire that sell a single screwdriver unit, which is far cheaper than buying a set. 72, Sandip EI7IJB

Re: Loosening tight screws
Amazon sells JIS screwdrivers.

Re: Loosening tight screws
Hermit,
JIS drivers are also available on Amazon.? JIS was introduced to circumvent the Phillips drivers patents.? The drivers are not as pointed and so penetrate deeper in the JIDS screw head.? The screws are also a type of binder head so locking hardware is not needed.

Re: Loosening tight screws
Mike and the group,
Thanks so much for link to McMaster, I definitely will be ordering from them, so much easier than directly from Japan.
Very best regards,

Joe N1KHB You might consider something like this: I have one and find it very well designed.? It has separately switchable 12V and 120VAC (600W) outputs, and a capacity of 250WH. It includes an input for a 12V solar panel for charging (standard XT60 connector) and also has a built in 120VAC charger that is VERY fast.? It can charge it from dead to full in about an hour or less. The front panel displays state of charge and also predicted run time at the current discharge rate.

Three 100W panels, special charging electronics and a suitable battery system. Car batteries are best value but heavy. Li batteries may take deep cycles well. NiMH less tricky, can be similar volume capacity to Li, but much heavier and expensive other than AA size. Lead Acid gel don't like repeated deep discharge.
Likely for a rig the duty cycle is 1:5 unless in a pile-up/contest.·

Re: Loosening tight screws
I agree on McMaster. They treat all customers the same no matter what size order, and delivery is FAST without special shipping charges. I used them for work and continue to use them for myself.

Re: Loosening tight screws
A small amount of heat. A heat gun or hairdryer will work. Assuming they have blue locktite on them, heat will soften the bond.?
I finally decided to attach the side rails that came with my Portable Zero Pack to my 817nd.? The two screws on either side are so tight I can only barely loosen one of them.? The other three are way to tight and I don't want to damage the Phillips head screw.? Does anyone know of a method of loosening screws that are so tight?? Appreciate any and all advice.

Hi All New firmware version V1.3 is already working in Maxicom CAT display for FT8xx transceivers A new IF for 28MHz transverter was added. This video shows Maxicom used in FT8 with FT857 and MET-4 4m transverter Of course you can also use it for digital modes in other bands not needing transverters like 432, 144, 50, 28, etc Kit price is EU200 plus shipment. ??m sending the main pcb already assembled and tested Anyone interested please contact directly luis (at) vigilant.es

I saw the same thing. Various manufacturers with dubious claims. I think it probably cost more, but I bought a small folding bioenno panel and haven’t regretted it.?
