VHF Band 1 and Band 3 frequencies
I am currently experimenting with a Band 1 modulator for 405 line tv, which I hope to be able to sell on as a kit, although early days yet. However whilst looking into it I needed to know what the various transmit frequencies were and having had no luck with internet searches, I found them in a Bush TV99 service manual. Here is the list all in Mhz which may be of help to other forum members.
Band 1 BBC;
Channel 1 Sound 41.5, Vision 45.00
Channel 2 Sound 48.25, Vision 51.75
Channel 3 Sound 53.25, Vision 56.75
Channel 4 Sound 58.25, Vision 61.75
Channel 5 Sound 63.25, Vision 66.75
Band 3 ITA;
Channel 6 Sound 176.25, Vision 179.75
Channel 7 Sound 181.25, Vision 184.75
Channel 8 Sound 186.25, Vision 189.75
Channel 9 Sound 191.25, Vision 194.75
Channel 10 Sound 196.25, Vision 199.75
Channel 11 Sound 201.25, Vision 204.75
Channel 12 Sound 206.25, Vision 209.75
Channel 13 Sound 211.25, Vision 214.75
There is a 3.5Mhz difference between sound and vision carriers with sound being the lower frequency in each channel.
Hope this might be helpful to others.
