Re: 7122 crystals
Hello Sam, It is a snow day here today.....Snow day Tuesday also.....It is giving me time to lay out a transmitter circuit board for 40 meters.....10 watts out with a power control.....In about a week or so, I am going to put up a shortened 40 meter dipole and get in some 7122 receive time.....I have bad propagated in RF noise, but, I am working on sound card audio filtering.....Through the noise, I have heard 31 countries, 200+ stations and 3 continents on PSK-31 on 20 meters in the last 2 months.....This tells me that narrowing up the audio will do the trick.....
For circuit board layout purposes, I would prefer the HC-49 case style, if I may.....

In return for this favor, I will extend my help and company to a brand new KF5 just across the State line down in Arkansas.....He doesn't have an antenna up yet due to our bad weather.....It may be that when I go to Arkansas to meet him over pizza, we may run out to his place and put up a quick and dirty dipole stuck up in the trees.....
Speaking about the State line, I am waiting on my last circuit boards for a pair of 10 GHZ transceivers, full duplex.....10 Milliwatts power output.....We have a lot of 10 mile,
20 mile and 45 mile line of sight hilltops around here with nice drive-ups and parking.....I will help the new KF5 get the 1000 Mile per Watt Award as soon as the weather gets back above freezing.....
If you are a county hunter, I am in Ozark County MO that has a ham population of 73 hams and as I remember, with the bulk of them on 2 meter FM and 432 FM.....I only know of 2 hams on HF and not on 40 meters, besides me.....
I have designed and built my own 1296 MHZ rig and I am working on a design for 2304 MHZ transverter.....I am trying to get Parts per Billion frequency stability on both bands and a total cost of $50.00 including a DIY antenna tripod using a freebie 18" dish.....The last power up on 2304 yielded a just barely detectable drift.....Almost not detectable.....Using an open circuit board exposed to room temperature.....
To keep my sanity with the 2304 MHZ transverter, I am programming the microprocessor for frequency steps of 100 KHZ.....Transmit on both bands is independent of any
2 meter transmit input as the transmit frequency is generated directly and the receiver is there only for an exact frequency receive on both bands.....
Well okay Sam, I appreciate the offer of a crystal and if there is anyway of repaying you for the favor, please tell me.....Thank you.....Gary...K5QNM.
