![]() One popular SSB generation scheme used by many manufacturers was to employ a 7.8 MHz Crystal Filter and the carrier frequency was generated at 7.8025 MHz which typically gives an Lower Sideband output when used in an additive mixer stage. Typical frequencies for the banks of crystals were in the 11 MHz range for the bank of six and in the 7 to 8 MHz range for the bank of four. Interestingly the first three crystals in the bank of four are separated by 10 kHz but the last channel is 20 kHz. Then the second crystal in the bank of six is mixed in succession with the four crystals to give channels 5 to 8. The bandswitch is arranged so that the first crystal in the bank of six is mixed with the four crystals in succession so that at initiation that would give channels 1 to 4. The typical crystal synthesizers uses two banks of crystals arranged in a bank of four and bank of six arrays. With crystals that raised the possibly to utilize commonly available inexpensive Computer Crystals to move the frequency to 10 Meters. After digesting those inputs I chose to look at the 23 Channel units since many of these radios use Crystal Synthesizers. I received many helpful inputs and suggestions. Thank you for your time.Untitled Document Conversion of SSB CB Radios to 10 Meter QRP OperationĮarly in 2009 I posted an inquiry on the QRP-L Reflector about any and all that may have converted SSB CB Radios to 10 Meters. I am having difficulty understanding how the lower crystal frequencies fit into the picture. channels as they were set up in 1976, and also my question likely has something to do with USB and LSB. Thank you for your time.I am going to continue trying to read about LSB and USB ![]() Am I looking at some kind of receiving filter situation? Does this older radio operate down into 11 and 7 MHz? So, I need to understand why the specifications in the online manual I found indicate the Pace Side Top 1000 B utilizes frequencies of 26.965 through 27.255, but the 'Crystal Frequency Chart' lists the crystals as operation at 11 and 7 mhz. I have no interest at all in transmitting, and won't be utilizing that function. Before that happens I have been trying to research the specifications to understand the radio and it's capabilities, before I lay my paws on it.įirst off, even though I have been scanning since the mid 1970's, I have never used anything like the Pace, or studied the bands it occupies. Someone has had a Pace Side Top 1000 B in storage for 30 years or more and is considering giving it to me. Commercial, Professional Radio and Personal Radio.We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. The benefit is you do not need multiple versions for each radio (unlike Motorola). ![]() The conventional package is more reasonable though is still several hundred dollars. The trunked package is in upwards of $2,500. One package is for conventional programming and the other for trunked programming. Often the Kenwood software is less than $100 so don't be a cheapskate just purchase it.įor M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. Typically each series or individual radio requires its own software package. Please use Google or some other search engine to find a dealer that sells the software. The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). To obtain Motorola software see the Sticky in the Motorola forum.
