Re: Anyone using FM mode on the Repeater Builder STM32 MMDVM board with an MSF5000?
开云体育
Richard
did you add dificulties connect it at your MSF5000?
do you think it would worked on a MSR2000 or a Tait TB7100 ?
thanks,merci

Re: Anyone here familiar with a Zetron model 42 controller?
开云体育Zetron did not use the standard pin out of db-9 connectors. Check in any of their manuals for the pin outs (don’t have a manual handy here now or I’d post it)Tom n7oep On Feb 24, 2021, at 10:09 AM, M M <wa6ilq@...> wrote:

Anyone here familiar with a Zetron model 42 controller?
Yes, it's a LTR controller, and not of much interest to hams...? but I'm helping a gentleman with an LTR system that uses the Zetron 42s....? and the manual sucks in the area of establishing serial communication with them. So a request.. if anyone here knows the magical incantation needed to make the front panel DB9 port work I'd be interested in chatting with you.? I have two systems each with several Zetron 42s and I need to drain the billing data. |

Hey Bob NO6B: if you want to suggest "removing Bomar from the crystal suppliers list" you need to contact the person listed at the top of that "suppliers" page. Clicking his name will bring you to a contact page.That's a rather bad advert for a company: buy our product, & maybe you'll get lucky & get one that works. I'll hold off on making a recommendation until I get my Krystaly order. If they work out I think it really would be best to replace the Bomar listing. Bob NO6B |
Re: COR Signal from HT1000 (or similar) for Remote Receiver
Eric Grabowski
Tony, while this may not work for you, I want to mention something our club did to maintain temperature stability at a remote site subject to wild ambient temperature swings. We mounted the remote receiver and link transmitter in a homemade wooden box slightly larger than necessary to house the equipment. Both the receiver and transmitter were crystal controlled and not in heated ovens. Then we placed a small incandescent bulb inside the box. This kept the equipment at a fairly constant temperature once it reached equilibrium. I don't recall if the bulb was one of the larger Christmas tree types or an oven lamp but either way it was not many watts. This was back in the 1970s. The radios were Midland ham grade mobiles. It was an inexpensive solution that worked for years until we had the money to upgrade to commercial radios with TCXOs. 73 and aloha, Eric KH6CQ

Re: True FM
We have to keep clarifying between the "tools" (modulator) and methods (how this tool is used).? I have a pretty good page about FM and other goodies (scroll down).

The problem was erratic behavior observed on the SA while tweaking the notch
capacitor on the cavity closest to the antenna TEE in the receive
branch. Touching the trimmer with an insulated tuning tool, as well as turning the capacitor, caused the
notch to jump around wildly. I pulled the loop and it all seemed to be intact. The solder joints looked shiny and solid, and there was no evidence of arcing. Several group members surmised the capacitor was faulty and recommended replacing it. Skipp and Jeff suggested trying to clean the capacitor first and then replace it if necessary. Jeff suggested removing the rotor and doing a visual inspection but I wasn't sure I would be able to put it back together successfully after cleaning it, so I tried Skipp's method. I figured if that didn't work, I could move on to Jeff's method and then if that didn't work I'd bite the bullet and have to replace the capacitor. Here's the procedure Skipp recommended: "Best to use a black sharpie marker to indicate the probe/loop position, remove it, then clean the disc edges with a real brass brush. Obtain some Caig Labs DeoxIT D5 (red can only), and flood the top of the piston capacitor. Then carefully exercise the capacitor throughout it's normal range of travel. Turn it upside down and use modest compressed air to "blow it out" then repeat the range exercise and blow out one or two more times. Return the probe to it's former location." That did the trick. I let the loop assembly dry for a few hours before re-installing it in the cavity. Then I adjusted the capacitor watching the notch on the SA. Nice smooth operation above and below the desired notch frequency. Notch depth was about -35 dB. The hardest part was obtaining the DeoxIT D5. While it's easy to buy on the mainland, no one would ship it to Hawaii. After a lot of fruitless searching I found an outfit that was doing stage rigging for a local production company and they had an extra can in stock. Since these capacitors are not easy to buy any more, I hope sharing my experience will help others in the future. Thanks to everyone who responded to my query. 73 and aloha, Eric KH6CQ |
Re: Sinclair Q202GC Duplexers.
The 4 connected directly to the cavities are 10.5" (cable end-end). The other 2 are 11.5". The cables to the Ant "T" are 13" & 14".
After trial and error I get the RX and TX down to 1.3dB ea. The Notches are HP 75dB and LP 87dB. Tuned to currently 146.84-146.24. The Tuning stubs in the notches are 5". I made new ones from brass and will silver plate them today. The old were copper tubing. -- Clif Holland KA5IPF www.avvid.com |
